Beaconing in iOS 26

Solid product and never had a problem in the past. Recently drug out my Mobilinkd and YAESU to get on the airwave again. Beaconing seems to be working in the app, radio transmits, app shows my coordinates.. but when I try to send a msg for weather or any other service that requires location it tells me to beacon.. I do beacon again and no luck. Everything else seems fine.

YobuddiVersion: 2.7.3
Great, but I have one big issue

I love how easy this app is to use, but my big gripe is that I can’t use this app with vox on my radio. As soon as I launch the app, the radio just starts transmitting, and doesn’t stop. I have tried the PulseModem app, and it works great with vox, I don’t know what the difference is in how the apps handle the audio, but it would be great if something could be changed to make this work, because the layout of this app is easier to use in my opinion.

Ender436Version: 2.4.1
APRS app that keeps getting better

All apps have issues and bugs. This one seems to keep improving without causing big changes that would make users hate the change. Excellent program. I hope they continue on the same path of improvement and integration with new things like the new external bluetooth APRS devices on the market. -KX4MQ

TechGuyTyVersion: 1.8.1
Excellent!

Perfect cheap way to get started with APRS. This plus a btech APRS cable (or make your own) and you’re up and running. I used an old iPhone without a SIM card, this app, and an old HT and it’s working wonders. Yes, there’s an additional fee for the built in TNC/modem and other features, but it’s well worth it - especially if you compare it to purchasing a physical TNC.

Natedog266Version: 2.3.0
Needs Offline Maps!

Overall this is a great app! Happy that it now supports the Mobilinkd TNC. I’ll upgrade to a subscription when offline maps are supported. Until then, APRSdroid will be my “go to” app for off-roading with APRS. When offline maps are supported (preferably using OSM maps), please make it possible to download large areas (e.g., states) in detail instead of the tiny areas that many map apps provide.

Great app!

I’ve used this app for almost 5 years. I think I had one issue over that time and the developer had that fixed in less than 24 hours and he is the one that found the problem. I have no complaints as this is a great app! de KA5MTE

Trains4oneVersion: 2.4.1
Not for remote use

Love it but…why do need to be connected to the internet to send an APRS message? This goes counter to the advantage Amateur Radio gives, and emergency communications. Fortunately you can see local radio stations without wifi. The message restriction is for me a huge issue which has been intentionally not included. Why?

AD7ANVersion: 2.4.1
Actually works!!

I was having issues with other apps but this one works for me. I got the app for $7 and for $7 a year I get all functionality in the app, not a bad price. Definitely recommend to get into APRS. I’m using a baofeng BF-F8HP connected to my VHF/UHF Ed-fong J-pole on the roof and it’s working well. Aswell as the B-Tech cable.

An Essential iOS App for Hams

If you have a MobiLink TNC and an iPhone, this app is a no brainer. I’ve used it on road trips, SOTA activations, and even to check into Winlink Wednesday when I couldn’t hit a Winlink gateway. Would love to see offline maps in a future update.

Link to Kenwood TH-D74

App works as advertised. I’m new to the iPad/iOS world. The install went smoothly and the graphics look great. My question: If I purchase the additional package will I be able to connect to my Kenwood TH-D74 handheld via Bluetooth. If it can will all the app features work. Messages, beaconing, etc.? 73, KB5FSG

Works very well

I really enjoy working with all aspects of APRS. I really wish that there would be a away of being able to delete messages in bulk instead of one at a time.

MillscoveVersion: 2.4.1
Looks good make an apple watch mini-port pls

I am just beginning my experimentation with APRS, and this app looks at least as good as any of the rest but if you could add an apple watch app, or mini-app, companion for the phone, that would be cool.

BadDomino5Version: 2.5.3
Promising APRS App

As far as I know, this is the only iOS app for APRS that supports an external TNC. The only TNC it supports to my knowledge is the latest Mobilinkd Bluetooth TNC. As the only such app, it’s great and I’m happy somebody’s developing a good APRS app for iOS. My only complaint is how limited it is - no messaging, no object, nothing APRS supports beyond position reporting. Hopefully this is made part of the app in future editions.

Does The Job

Meets my needs. Keeps on getting better. No app is perfect. I’m always pleased when developers put time and effort in applications that serve a relatively small community compared to the general population. Gary AA1UE

AssetprotectionVersion: 2.5.3
Great app

I do like this app, I realize that it doesn’t transmit to the IS servers but that’s coming in a future update. I do like to use it to see where other hams are at. Will be nice when messaging comes.

The best

Hands down one of the best APRS apps on the market. Easiest to use and has every feature you could want or need. Was hesitant to pay with all the other free options out there but I’m glad I took the plunge.

Police3534Version: 1.6.6
Pretty good, but a little expensive

The app does what it’s supposed to do, but not sure the luxury of a dedicated app versus the website is worth a full $7…just my thoughts. Aside from that, I love it…works great

Solid app

Solid interface. Very intuitive. Provides lots of information that is easily accessible.

Wasn’t sure it was working

Usually it works well, but today it said that the service could not be reached even though I was told that it was beaconing.

APRS app

Great app with Mobilinkd TNC and works on my iPhone. There are some small features they should improve for ease of function but I’m otherwise very happy.

Love It

Now my radio is sending correctly (Yaesu FTM-400) I show up on the map. I want my 98 year old Dad to be able to track me when on the road. Works great.

Jad742Version: 1.9.3
Please add

I’m using the app with a Mobilinkd TNC3. I’m finding the interface to be easy to use and straight forward. I would like to see the ability to send and receive APRS messages as well as straight packet.

Huge improvement for use on my UV-Pro using the BLE TNC. Huge improvement over the BTech APRS functionality in the app.

App works great, Developer is always doing updates.

App works great, and the developer is always working to update the app. When iOS 13 came out on beta it broke the system with google maps. I emailed the developer and he responded pretty much right away saying he is working towards a fix. Two weeks later a new update and its working. Great job with the application. And it works with Darkmode. Pretty great app, worth the purchase price. VE7PMD

RF Only

I was able to post my position and exchange messages while not having any internet access. I was in a group that helicoptered into a remote location were there was no cell service. I was able to receive APRS signals from my location, make a contact, and exchange messages. Tried to establish voice, but was unable. My phone worked well as a monitor for displaying the data etc from my handheld radio.

Aprs.fi Negative Reviews and Ratings

Good APRS app with some caveats

For iOS, this is the APRS app to get. It's surprisingly full featured and has been stable for me so far. It's not without fault. One biggie is that for some reason the app tries to connect to a TCP/IP KISS TNC on my local network, but has no option to tell it directly where my network TNC is. The more prevalent way to connect to, say, Direwolf or APRX is to enter the IP address and port number of those apps. The other issue is general UI. In APRSDroid, one can have a view where only raw packets can be seen on a list instead of a map. Here, the same can be done but only per user via "Track". Perhaps the feature is buried somewhere but I can't find it. It would help if there were a single place to get all settings, instead of having them strewn in m. For instance, the beacon button has its own settings... Additionally, each time I run the app my filter settings default back to "network" being on. To the developer: please save state? There are also three settings for beaconing, one of which is "beacon my position" ... which enables beaconing when the button is pressed. Maybe just grey out the beacon button if it doesn't function? Also what does "RX iGate" under the other settings menu do? It's not in the help. Much is missing from the help in general. Another tip, there are yet MORE settings under Apples prescribed Settings for the app, but not those for beaconing. This is a great little piece of software, and with a UI design and help file update it's five stars.

AeroDVersion: 2.3.0
Beacon Settings Needs to Be Better

Update: Not much change. I really want to like this app and give it 5 stars but I can’t. I use it but only with reservations and some disappointment over its operation on beacon timing and lack of a working filter. Original Comment At first glance, the app looks pretty good. Really liked it. After time and considerable usage, not so good. I started using app because radio beacons are unreliable in my area. I needed a more consistent result. This app is not it. The controls for beaconing is fixed set to a min beacon of every 5 minutes as the fasted rate you can get. Any faster is up to the app with no insight to how it chooses to beacon. It could be 30 seconds or it could be 5 minutes. I found it taking 4 to 5 minutes between beacons. At 40 MPH, this means the beacons are as far as 2 to 3 miles off. Not useful for me. I need last known position to be accurate to hundreds of feet while traveling. Not miles. I went back to radio where I control the beacon rate which makes sense for speed and accuracy. Unable to get filtering to work. I want to filter on a single station. Entering the call sign doesn’t do it. Enter call sign with wildcard asterisk doesn’t work either. No guide on how to use filtering.

KB0SISVersion: 2.5.3
Can’t use it

On the surface this app seems like it would be great. The drawback is if you actually wanna send a message or anything it’s a subscription. I’m OK with that generally. The problem I have is there’s no way to go online and subscribe you have to do it through the app. The app has no provision for adding a payment method. The one and singularly option. Is to use the exact same card you’re using for Apple Pay. That does not work for me as the card that is being used for Apple Pay is for that alone.. I don’t want to use that card to make in app purchases on other apps. No option to change payment method.

JimjrflVersion: 2.6.1
Paid subscription needed for TNC use

This looked like the perfect way to use the new Mobilinkd TNC for iOS. However to send or receive messages you have to pay a subscription. That’s right, after already paying $9.99 for the app they want another monthly or yearly subscription for what is a basic feature of APRS. Without this the Mobilinkd TNC can’t be used to send or receive messages. The screenshots on this app on the store make it appear to have this messaging functionality. You don’t discover the additional subscription until you download. Quite frustrating, it almost seems like false advertising.

UmiDevVersion: 2.0.4
Three stars! Yep three…

Why though, we’ll because I just paid $6.99 for this app and upon opening it, I find out that the features I needed are behind a subscription wall. Really? The whole planet is going to this? We don’t buy our products or software and own them anymore? We only get a mutilated parred back version. I’m sick of this predatory behavior by every company on earth. This is sickening. Unless your tech is so cutting edge and updated so often that it requires a subscription to pay a team of engineers or you are just digging in our pockets because you can. This is what is eroding our ethics and economy, this money hunting. It’s constant and from all angles. I hope one day it stops. Other than that the app works. Three stars.

MightyBohabVersion: 2.4.1
Like it but……

I’ve had this app for about a year now. Paid for the extra features to message. Can send a message and I receive it in my radio, but it never says that it was sent. It will time out and say not sent when it sent a message every time it tried to send. And when I reply on the radio it sends from the radio and I don’t receive it on the app. What am I doing wrong?

Tpaugh1975Version: 2.6.1
Not what I consider APRS

Wasted my money on an app calling itself aprs.... that does not talk to any aprs not using aprs-fi. Packets are NOT transmitted into the aprs network so you can not be heard by hams monitoring. This fact is buried derp in the about section of the app. It should be stated plainly on the app store page. Would never had purchased it if this fact was known. Lake of this ability completely destroys all the features it has. ( like a Cadillac without wheels... all the plush in the world but the deal breaker is it cannot move)

MrWzrd2Version: 1.9.3
Background location is a battery killer

With location access always on, the app my iPhone battery extremely quickly as seen in Settings/Battery. I reported this to the developer three weeks ago with no response.

The Original RoyskiVersion: 2.4.1
Overall way too limited for 7 dollars

This app is far too limited for the upfront price. To unlock much of the functionality, you’ll be prompted to pay a subscription. Most frustrating, why can I only see 3 hours of tracks in a paid app without a sub. Just use the website. Too much paywall nickle and dime here.

DeependstudiosVersion: 2.5.3
Bait and Switch?

Very disappointed, paid to purchase only to find out after doing so you need to pay an additional subscription to be able to use the app and some of its most basic functions. Seems a bit inappropriate to not clearly make this aware to purchasers. Leaves one with the feeling they’ve been duped.

73TriumphVersion: 2.4.0
Double dipping

Amateur radio, where everyone everywhere tries to squeeze every cent out of you that they can. This app not only has a purchase price, but that only buys you the privilege of paying them more money with an annual subscription. Yay!

Midnight MDVersion: 2.6.1
No messaging without subscription

Messaging should be basic functionality. Charging a subscription after purchase for basic functionality is not appropriate. Make it clear in screen shot (not just in text) that it’s not included unless paid for as part of subscription.

N3PPDVersion: 2.3.0
READ ONLY

Although this has the best user interface for iPhone APRS apps, it’s functionality is critically limited. What you find only AFTER purchasing is that the app ONLY reads data from the APRS internet database. It will NOT broadcast your position. It also lacks interface capabilities for Ham Radio. It’s fine if you want to track others, but there’s no way to interact with others.

BriEyesVersion: 1.6.6
Don’t buy

I am thoroughly disappointed and feel like I’ve been ripped off. You spend seven dollars for the app and then only to find out that 90% of the features that you will use, you have to buy a subscription.

Chris1165Version: 2.3.2
Please add messaging

The app works flawlessly! However, not being able to send messages when using a Mobilinkd TNC is very frustrating. I would give it 5 stars but without messaging built in the app I can only give it 3.

Doug RehderVersion: 1.9.3
Not as expected

Very disappointed with this app…it is a paid-for app and i fully expected that for the fee i would receive a fully functioning app but instead i found out that i have to subscribe for a monthly or yearly fee to get the features you need to operate that wasn’t clear from the description in the app store

VE3PLUVersion: 2.7.3
Too commercial for me

APRS-IS

Global ReachVersion: 2.3.1
Just Ok

Using with a Mobilinkd TNC and it’s just ok. Able to send position data, but no messaging. APRSdroid still has this app beat for features. No messaging. Can’t really recommend this app yet, as the free .fi website is more useful.

It's a cool app .., if it wasn't so buggy, freezing between screens , app closes for whatever reason, locked on settings screen and couldn't get out no matter what I did , had to delete and download again, and all for 6$ ! Not worth it , don't do it ... Take your 6$ and buy a coffee or 2 and a snack ..better deal ..
