An archery toolbox for calculating proper arrow spine.
In-App purchases unlock Premium Features.
The app uses a configuration created from the user's bow definition and desired arrow parameters.
It is the only handheld app available for shaft selection that is based on bow performance. It has the same features and flexibility as the desktop app available from Pinwheel Software.
You can search by shaft manufacturer, shaft construction (aluminum, carbon, aluminum/carbon), and shaft usage (target, hunting, both).
You can search the database for a specific weight range for a completed arrow (with your components), a shaft diameter range, or a specific percent FOC range. Choose to include or omit discontinued shafts.
Flexible, Accurate, Unique.
OT2Go Spine Positive Reviews
Same as On Computer and way cheaperI have no idea where these negative reviews are coming from. This app is the same info as the one I have on my computer. My suggestion would be learn how to use the program before you start saying negative things about it. Sure there’s a bit of a learning curve but nothing an average person can’t figure out. Took me an hour or so of playing around with it the first time I used it on my computer and I was all set. I down loaded this app and it basically took me 5 min. I input the same info I had on my computer at home and got the exact same result. I paid $30 for the one on my computer and this only costed me $5. I have 3 different arrows that shoot lights out. Very happy with this purchase. Good job with this app! BTW I don’t work for or know the owner of this software This is my none biased opinion..Tmorg50Version: 1.6
Valuable tool for the serious archerI’ve been using this app for 3 months, and I find it to be a must for tinkering with arrow setups.
When I first started using the program, I didn’t understand how to change the parameters correctly, or search for arrows, and this led to some frustration. But after taking the time to learn the program, I am so appreciative of the work put in by the developers! I’m happy that the database is very up to date, and even included arrows that hasn’t been released yet... only announced! I bought the new Victory VAP SS based on the info I was able to glean from this app.
There is nothing else like it, and people who are giving this app negative reviews need to take the time to learn the program and input the correct information to get the desired results..AZArcher1111Version: 1.6
Spot onUsed this program to build my heavy arrow setup for elk and it was spot on. After all data was entered the fps came out within 1fps of crony. The learning curve could be slow for computer challenged people but for the price this program is money. To compute insert weight I entered all the fixed data such as specs of bow and my draw length and weight, arrow length, fletching ect. I then played with insert weight until I got optimum spine. I used adjustable inserts from Ethics Archery and started heavy and tested 1 fletched arrow compared to bare shaft. The first setup was 15 grains heavier than the program suggested and bare shaft didn’t group with fletched. I trimmed the insert weight to match the program and both fletched and bare shaft grouped and shot bullet holes in paper. I now never shoot broad heads and field tips at same spot..PopsbrothersVersion: 1.6
Customer service top notch!Got this app to help make some decisions on some new arrow set ups for the upcoming season. A couple bucks (for upgraded feature) to help make a decision that will cost a couple hundred is a no brainer. Had a few questions and they got back to me right away with above and beyond help. Really cool to see/experience top level customer service!.Jglv48Version: 1.6
Excellent appYou have to purchase the premium options to get any use from the app, but it’s still only around $5 total. The initial app purchase is useless without these options.
The app is easy to navigate and will help to choose the perfect arrow configuration without having to try all of them in the field. I would definitely purchase again..Just PimpingVersion: 1.6
Needs improvementI have the windows version of this and love it. I contacted the developer about some improvements. Hopefully I’ll get a response and I’ll update review accordingly.
Update: developer emailed me within the hour. Everything I wanted was already there I simply had to flick the screen up..TraviswdaltonVersion: 1.5
Poor ratings? You don’t know what you’re doingThose giving it poor ratings you don’t know what your doing. Not entering complete and accurate data. Not buy the complete package to work best..Rabbit1957Version: 1.6
Wish I would of found it soonerThis is a great app it’s spot on for everything I’ve plugged in. Really helps if you are building high FOC arrows and gives you peace of mind when shooting 200+ grain points..Mike70007Version: 1.6
Good ProgramI like that I now have a spine program I can compare arrows when I don’t have my computer with me. It’s great to have on the road. It gives you a good reference to pick your arrows and play with different setups..TN3DJackVersion: 1.6
Not all arrows presentLike the app as a whole. However, I would like to see all arrows present. For example, I wanted to check into the Sirius Orion’s, but they’re not included in this app..Bryan w 32Version: 1.6
DecentI like this app but it needs updated. Two years is a long time and new stuff has come out..O119510Version: 1.6
Incomplete app IMOI’ve been at it for the better part of 24 hours now. I can live with the xtra in app purchases. It’s in fashion now a days. Works well. Seems to crank out numbers that are very close to reality.
Giving a 3 star rating because I can’t customize the rear end of my arrows. I shoot with nockturnal nocks. And shoot a few custom arrows for specific applications ie.: turkey hunting. So for a 5 star rating the app would need customizable vain, nock and nock collar weights..The-little-oneVersion: 1.6

Doesn’t seem to function rightEven after purchasing the “premium” features, this app does not do anything useful. It will not load a database of arrows to choose from as described. A google search seems to show people have been having issues with this app since 2019 and it has remained here with the same problems. Please fix this app, it’s practically a scam to leave this non-functioning version on here for years on end..Dave0317Version: 1.6
UselessControls are clunky when sliding the pointer to desired value. Your arrow selections are also limited. When you configure your arrow and set up, you have a list of 5 arrows of which I’ve never even heard of to experiment with. Where are the Easton/gold tip/carbon express arrows? I would’ve thought you would at least get those as an option. You also pay for the app, but still have to pay more for the “premium functions”..Tus HlubVersion: 1.5
Don’t waste your time and money!The .99 version pretty much does absolutely nothing except tell you that you need premium to be useful. Absolute waste of time and money.
No manufacturer search available and all useful features disappear after 5 uses.
Normally I would move on but this one I think I’ll file a complaint just to get my $1 back..LscammeyVersion: 1.6
Pay to download pay to useNot useful for much of anything. Paid to download thinking it would have the arrow database included. Just 1 for a no name series of arrow. Pay $3.99 more. Want to save pay more. All said and done be looking at $10 plus to have a functional app that probably won’t be functional. No idea how apple allowed this to be in their store..ShorteraarVersion: 1.6
Don’t waste your money on the mobile appThis version doesn’t even open up in my device anymore after purchasing the premium features. I’ve deleted the app and restored my purchases, only to be kicked out of the app and unable to re-open it. Junk..Knockout96Version: 1.6
Biggest Scam for .99 centsThis app is a complete scam! Don’t buy it. I paid .99 to try and see my FOC and it doesn’t work period. You pay .99 just to download the app. Once in the app, if you want to use anything it costs money to buy premium features. It doesn’t even give you a database. Complete garbage!.Mulletman925Version: 1.6
Worthless without in-app purchasesWithout purchasing premium features you can’t save your setup, so you have to input your specs every time you use the app. There is also no access to the arrow database, so you’re stuck with worthless data about arrows you’ve never heard of..WhizwheelVersion: 1.6
$.99 version doesn’t match photos or description.You have to pay extra for the arrow database and only get 5 chances to use the quick change page before having to upgrade to premium to continue use. Sneaky slimy..StevebobkarenjoeVersion: 1.6
Bad resultsI was skeptical of the app because it did not match the arrow manufacturers recommended spine. Sure enough the two shafts I purchased based on the app results where under spined and not tunable. Not only did I waste $5 making this app usable I wasted $24 on under spined arrows. Save your money and just use the arrow manufacturers recommended spine chart..Jon.dingoVersion: 1.6
App crashes after downloading 2022 database.Just like others who experienced the app crash after paying $3.99 for the in-app purchase of the 2022 database. I should have listened to those other 1 star reviews. I have an idea for the developer…fix the issue!.Airwolfe1Version: 1.6
WorthlessAbsolutely horrible UI, the app the totally worthless without paying for for in-app features to make it usable. Cannot select from arrow database for any arrows anyone has actually ever used, the app purchase is basically a scam bc you can’t do anything with it.JT19821266Version: 1.6
Not worth the $.99I would have given 0 stars but that’s not an option. Doesn’t come with instructions for use and is not intuitive. Seems like an app that has only one function, and that is to tell you nothing works until you pay more money..EPLC45Version: 1.6
Dirty trick WARNING!!! Do not delete User RecordI feel I was taken advantage of!!!
Why not warn the customer?
I really liked the app and I purchased all the premium features thinking that I had access to everything I needed. However I soon realized that if one deletes a configured user record it’s gone forever and one has to pay to have more user records.
I am glad to pay for services I received as I did but this feels like a dirty trick.
To the developer
Please remove the “delete UR”, from the app so no one else makes this mistake..Theotherone71Version: 1.6
Scam!!!!! Do not download app!The app is useless!!! You have to pay for premium service after you download app and still doesn’t show current manufactured arrows. This app is outdated and needs removed from the App Store. I want my money back!.HoosierbuckhunterVersion: 1.6
No access to previous purchasesRequires you to purchase user records after every uninstall.
Also does not give you access to previously purchased databases.Prove me wronfVersion: 1.6
Limited functionalityIt costs money to install this app which only calculates a few basic arrow attributes many of which may already be available online for free.
There is a bit of a nickel and dime system for adding more useful features bit by bit.
However, from what is seen in this paid demo and other user reviews it may not be worth it.
Also, it is a little misleading. This app should be labeled as a demo not a full app..::::::V::::::Version: 1.6
MisleadingThe app is pretty misleading when it says .99 cents. It really means 99cents for generic arrow setups. You cannot access manufacturer specs or anything without spending more money. Should have went with Archers Advantage because you get what you pay for..TBow130Version: 1.6
Don’t waste your moneyThis program may work, if you buy all of the optional add-ons. They’re trying to nickel and dine you to death. Pass on this one.Zipper197942Version: 1.6

Limited in optionsNo selection for specific bows. Must manually type in all specs of it which is a pain. To make the app even remotely worth while you need the in app purchases which is a joke. Why not just charge a flat rate for a quality app up front. I’d hands down pay 20$ for an app up front and get all the settings in. Also not very well laid out. Save the cash and just buy the desktop version and avoid the headaches.Craig/kraigVersion: 1.6
