Needs CRM IntegrationThis is the only reliable non-VIOP based 2nd number I can find with an independent contact book, however it NEEDS integration with 3rd party services. As of now I have to change my contacts information in multiple places..A1M4THABUSHESVersion: 1.56
Five starsI heard about this app from my hair stylist and decided to give it a try for my own business. I like that I can save the phone numbers in the app but not on my phone, so it doesn’t mix my customers in my personal address book. It also has this window pop up at the end of a call asking if I want to take notes which I find very handy. The Appointments feature is fantastic once it’s set up. I am paying a lot more for a similar tool right now. Definitely will not renew that! There are still a lot of features I haven’t had a chance to set up yet, but I’m liking it so far!.HZJ031Version: 1.24.1
Compared to other #1I’ve tried several competitors and this has won. Sending out blast, text payment links, special text sound and keeping my personal number private was my 1st, goals. I’ve been around several years and it keeps getting g better. When I’ve had a problem, the response time is quick! Thanks for features I’ve not used yet too. Plus when you send group text, the response is directly to you, so others don’t see it! Another great feature and list goes on!!!!!😊.Finally Very Satisfied!Version: 1.61
Caller ID doesn’t workI’ve had this app for years… it used to be call sideline… this app was the best option at one time, then something happened and stopped displaying caller ID for incoming and outgoing calls… I’ve reached out to customer support numerous times and they tell me the same thing every time… delete the app and reinstall, maybe it’s you service provider etc. This is my tenth time deleting this app and reinstalling even though that never works… I hope they are seeing this comment and will help me solve this caller ID issue once and for all. If they fix the problem I’ll delete this review and rewrite another one..HhhhhhhjbbbbbbbVersion: 1.36
Would like to knowI Would like to know how did I get transferred to this app I had sideline and it was working fine then I got switch to this company and the app has bugs. I was told to update the sideline app and it updated me to this app. Then I was told that sideline was being bought out by this company, but my husband still has sideline. This app will get stuck and I would have to shut the app down and restart it to get it unstuck. Once I finish a call it will stay stuck with the last contact called and I can’t make another call unless I restart the app. I miss sideline. 😞.AE820Version: 1.44
Good for BusinessI have been using the Index app for several years. Overall, it has a lot of good features for business with the templates and auto responses. Very rare. I have had issues with being able to make phone calls or receive text via for Wi-Fi. Overall, it’s been a great side number to keep business and personal calls text separate..Realtor CBVersion: 1.56
Perfect for texting customersThis app let’s me respond to customer calls with texts. Saves the hassle of having to pick up the phone, especially when it’s spammers. My real customers get a text with my logo and we continue the conversation over text. All my customer communications are stored and I can put customers in categories so things are organized.Olaf972Version: 1.34
Great business numberThis is a great app. I have two lines from them when I ported out and the other one I still have. Use it as a 24 hour on-call number for our business. Cheaper than buying a second cell phone and I like the fact that it shows you that it’s a call from the app..MrsAriaTVersion: 1.54
Love the business features!Index has some great features to help run my small business. I really like using Appointments as it makes it easy to enable my clients to schedule an appointment with me automatically. Also, I’m able to request a business review and a payment by sending a link. So easy!.Allie_2018Version: 1.34
It’s like having a personal assistantI’m blown away. The auto response feature helps me a lot because it lets me reach customers that I would’ve lost because I missed their call when I was busy. It’s really nice to schedule appointments through texting once it’s all set up too..Slopasaurus RexamachismoVersion: 1.34
Makes life easierIndex is great, especially the auto reply feature which sends a text to my missed calls. Now, instead of “missing” conversations they’re sinply moved to text and I can get back to the person in a couple minutes when I’m free..Johnny2089Version: 1.34
Mass Messaging and Call ForwardingThese are the two best features of the app, in my opinion. I had to import my old business number from another application, which works great. Also, mass messaging (aka Broadcast) is great to reach my clientele all at once..Carlosll21Version: 1.34

Bugs (Phantom red alert notices)…The app itself is great, but I have 5 phantom red notices that say I have alerts, but when I open the app, they’re nowhere to be found. It started at 3, now it’s 5. Please fix..The dawg2131Version: 1.30

Easy to use. Amazing features for the money.I love this app for my small business.
I can make a set appointments while also requesting payments via pre built links.
What’s more is they keep adding features and I was able to use my old Sideline Pro (another application by the parent company Pinger) subscription for a reduced price.

Index: Business Phone Number Negative Reviews
Reminders brokenI’ve been a Sideline customer for 3+ years and I have to tell you that the update to Index is less than ideal. What was once an easy to use and relatively fluid user experience, the new system for booking appointments is cumbersome and inefficient, specifically in regards to the reminder system.
The ability for Sideline to communicate with my iCloud calendar and propagate customer appointments and phone numbers from the calendar and into Sideline made reminders straightforward and easy. Furthermore, the control and customization of the reminders made this feature vital for customer communication.
The new system which forces you to book appointments *only* through Index makes scheduling frustrating and laborious. There is no indication through Index’s calendar which times/slots are available until you attempt to book and then it only tells you if a spot is unavailable after attempting to confirm a booking. To solidify the frustration there is no indication within Index, unlike in Sideline, whether or not a text reminder has been sent to clients.
Please improve upon or reinstate the previous reminder functionality..Bryan!Version: 1.46
Will the REAL PHONE APP.. PLEASE STAND UP?!I am so confused. When I first bought this app, it was transferred over from Sideline. Another words I was told that it was a merger between Sideline and your app ““ index. However, upon having it for at least two to actually four years now you guys have circumvent changed the apparatus in there in which I am being charged way more than previously entertained or contracted. you guys up the pay on the contract or up the payment requirement on the contract without any notice on your behalf, or towards mine. Subsequently I had to let the app go which I’ve had for four years the same phone number because you guys decided to raise the price $10 from 1499 to 2499. Now, the fact remains that I did not sign up for 2499. In fact, I originally signed up for 999. I want to know why it is you guys want to charge 2499 and I have no access to my old line anymore will I get access to my old phone number if I continue my subscription I do not want to pay 2499 because that’s not what the agreement was. I will contact my lawyer if this issue is not Resolved within 24 hours and 99 seconds..AllStarHoodPlayaHataVersion: 1.61
It’s ok WHEN it works - inconsistent at bestI was also a former user of Sideline. I was terribly disappointed when the update, not only changed to Index, but charged more for services I received at a reasonable rate through Sideline. I was given a credit for the inconvenience, but I doubt I will keep the service.
I never know if my customers get my texts because a lot of times they don’t. It is completely unprofessional and embarrassing as a business owner. Also the auto-reply is hit or miss. This is not a cell service issue. I can have 5G and still have customers I follow up with who never received my text or who contact me again because they think I never responded to their inquiries. Completely unreliable.
The scheduling aspect is rudimentary and only works if you have one person on the schedule because it only links to one calendar. I hope they improve by leaps and bounds because I will jump ship as soon as something better comes along..Delnie MarieVersion: 1.44
Missing text messages from clientsI don’t know what’s going on lately but I have had multiple clients of mine saying they sent me text messages but I don’t have them. This is very frustrating as a small business owner who relies heavily on being able to send and receive text messages seamlessly. It really makes me wonder how many potential new clients have texted me but I haven’t received their messages. I had none of these issues with Sideline so it’s extremely frustrating that it’s happening now. And it’s also very inconvenient to be forced to keep the sideline app to keep the pricing sideline had us at. Phone storage is precious and it’s way weird to be told to keep a old app to keep your price the same.
At this point I will probably keep using the app for a little bit but I am saving some money to just buy a business cell phone because I can’t afford to lose thousands of dollars due to clients not receiving my texts or me not receiving theirs..Jenifer610Version: 1.52
Avoid at all costsWhen they were Sideline this company was reliable. Since the transition, this has become the worst service on the market. They transferred my number and it immediately stopped working. I reached out to customer service and they told me that I wouldn’t be able to get in touch with me again until after the weekend. There were still two hours of service time on the clock when I reached out and they informed me to “just wait until Monday.” I run my business on the weekend and informed them of that, and they had no interest in helping me until a later date even while continuing to text me. They charged me for services that were never provided and continued to be unhelpful all throughout my contact process. They charge more than Sideline, have non-functional features, the worst customer service, and no discernible interest in improving. Avoid at all cost!.Cam4O4Version: 1.59.1
Sideline was betterLike many other reviews, I’ve been a long time client of Sideline for my business to get a custom phone number and to be able to send mass texts. Back when it was Sideline, I haven’t had any issues.
However, since switching to Index, the biggest issue I have is with Broadcasts. I use Broadcasts to send mass texts to all my clients, and maybe 1 out of 20ish people will get the text, or sometimes not even 1 at all. If I try to add someone onto a Broadcast, numbers get removed. So I add them back on, and just removes them.
Then with incoming, some clients said they texted me, showed me on their phone, only to show them back that I never received it. It’s embarrassing.
For a business tool, those two issues are crippling enough. What kind of communication tool can call itself that when it can’t do the simple things I need?! And I’m paying a years worth subscription at a time for this. If I’m able to keep my business number, I’d switch out of this app and leave Index permanently..KungFuriousVersion: 1.37
Sideline was betterI had Sideline for 3 years before it switched to Index. Since then the quality has gone downhill. I often don’t get new text message alerts, calls drop after 1 ring, or sometimes the call never rings me at all and I see much later on that I missed call.
As of lately, I couldn’t pull down the complete text message to read it. It makes you click on the typing text message field and then it will move down. Ugh. It’s disappointing and disruptive to my business phone line.
I also don’t see very many updates from the app to the glitches several people have mentioned..Urbanite2017Version: 1.34
Don’t BotherI started using this service years ago when it was Sideline. Since being migrated to Index from Sideline I’ve had several issues - calls are silenced and now cannot make outgoing calls. I use this application for business, and these problems certainly have prevented clients from reaching me. Contacted support several times over the last several weeks, and nobody seems to be able to correct the problems. And support is only available via e-mail and chat. Consider another application. Just do not purchase this one. Once you need help, it will not be the best..Marsville617Version: 1.32
I HATE THIS APP!!!!I had this app since it was Sideline. It was good at the beginning, then they did the switch, no caller ID working, lagging all the time have to turn it off and on multiple times for it to work. I use this app for business and needed a reliable source of communication and so far nothing but just issues every day with the app. Not to mention the issue I have with my contact list that it’s all saved on the app. Contacted customer service several time seems like they can’t really get it fixed..RikagogoVersion: 1.45
Appointment Reminders feature!!!Fix the appointment reminders feature ASAP. My entire business runs through outlook and for some reason now I can only send appointment reminders to clients if I use google calendar…. This makes no sense, just a short time ago it didn’t matter what platform you used. Not only that but even to use the feature with google calendar it’s annoying since you can only book appointments through the index app. Very disappointed with the changes and am considering other apps if this doesn’t get fixed soon..Boss777101Version: 1.49
Horrible comms. Horrible dev. Horrible app (mostly)Only use them because they seems to be the least of the worst. That said, this app is junk. One example: customers that pay for the app don’t get some of the features that are in the free version. Like, the ability to have one sideline number on two phones. This would allow coworkers to share responsibility instead of defeating the purpose and having to share the phone. After 2+ years of battling they finally just created a new app and didn’t tell any of the paid customers….Sideline TRASHVersion: 1.44
Bugs and less functionalHave a issue where you don’t see contact names when somebody calls or messages even if they are saved. It’s been 4 weeks since issue is reported and followed up still no solution. App lags in continuous connectivity, at times you might not receive calls and get messages later. Need separate tabs/screen for calls and messages(this is so basic thing)..Pixel 1234Version: 1.49
Into the dumpsterI was already having issues when it was Sideline and I have even more issues now. Not only is the Auto Reply to Calls with Text Message very inconsistent, I’ve had caller ID fail, and, one of the worst things, text messaging malfunctioning. Clients and potential clients think I’m ignoring them. I am looking at different apps to hopefully port my number to. If not, my best bet is to buy another phone for business..DarksunscorpioVersion: 1.52.1
App has been having issues with callsIt’s been about three weeks where the app has been having issues with calling and receiving calls. For about three weeks the app has been unable to make or receive calls on average 4 days per week. Unacceptable for an app that describes itself for “business” will be switching to something more reliable after my subscription ends..Santi-SteveVersion: 1.37
$300 a year!?!?!?!They want a whopping $25 a month which is $300 a year or you can pay $200 up front for the year. Sorry, but this app has become too expensive now. I’ve been using sideline which is now index for around 8 years, I think it might be time to look for a new second line. There are so many cheaper options. ATTN: PINGER. Please make a discounted plan for veterans or loyal customers that use your app every year. Bummer.TeamjajooVersion: 1.37
CarefulI was using this app for product sales from my social media, using specifically txt, my account/# was abruptly suspended and hundreds of my txts with customer shipping addresses disappeared.
Reason: was told my account was a spam account from the amount of txt going in and out, I did not do a single automated message, every txt was literally typed by my thumbs lol, anyway if u use this app be aware that you can randomly lose all txt msgs.I luv these birdsVersion: 1.60.1
Click to see the most recent reviews, that tells the story.I never write reviews but this is crazy.
Index is horrible, sideline worked flawlessly, now, annoying issues all day….couple they with the fact that they raised prices.
My incoming calls have a delay and sometimes won’t even ring, just pop up a missed call.
I always end up soliciting a review when trying to send a text because the UI is horrible and all the buttons are jammed together.
The caller id doesn’t work in real time, it looks like everybody is calling from the same number.
It’s clunky, and buggy…. I’m about to start looking for better options..No cappington 🧢Version: 1.49
Sideline was betterI can’t scroll all the way to the bottom to see the message. Maybe it’s because of the buttons at the bottom. I have to press and hold it long enough for me to read it and goes back down. I’ve had this ONE new message indicator on the app and there is no new texts or voicemails. Please fix the problems with the app..Meo9Version: 1.32
LISTEN TO THE BAD REVIEWSListen to the bad reviews on here !!! They have terrible customer service. They will just quit replying to you before your problem is resolved and don’t care do not get this app. Whatever you do especially if you have to port a number because then you have to pay to port the number out to a better app that’s not index..Doglvr23Version: 1.51
Used to be great.I have to find another app to use because this is causing major issues for my business. I relied on the automatic replies big time. I am unable to answer the phone when working. When someone calls there if no longer an automatic message sent and they can’t even leave voicemails anymore..EsmargoVersion: 1.39
Highly Disappointed!I’m highly disappointed!
I LOVED Sideline before it changed to Index.
It had caller ID & was overall a better “bang for your buck!”
Same with the previous review… I’m really upset about no Caller ID!
As a female small business owner, I like to know who is reaching out to me! Safety, in today’s world, is a priority for me!
I do enjoy the same call quality for the most part but once you had something (caller ID, you really miss it once it’s gone!
PLEASE Index… get your caller ID back!
Nothing really separates them from the rest without the Caller ID.
Sadly.Olive21!Version: 1.51
Do not pay for this garbageApp doesn’t work. You don’t know whose calling. All call ssay “incoming sideline call”. You don’t get notified for text messages as well. They’re constantly banning me for “spam” when I’m texting and calling clients. Sideline pro perfect. Index is a dumpster fire. Save you’re $15 a month and use on on an app that actually works..Jj25a7xVersion: 1.49
