I have had excellent results with the ballistic app. I use it for 22lr and once you have all your information input it is spot on. I have also helped several folks set theirs up at the range that didn’t have anything and it was a great quick way to get them some help for ballistic s so they had an enjoyable day.

Hi there, thank you, and thanks for helping other shooters at the range! Version 1.1.1, now on the App Store, adds automatic chronograph connection, a new Live screen and more reliable session backup. Please update to get the latest improvements.
Was ok until it wasn’t
I had a lot of data and range sessions in the app. One day it just crashed and wouldn’t open again. I restarted the app, my phone, etc. Didn’t matter. I finally had to delete the app to reinstall it, hoping data would still be in there. NOPE. All of that data—POOF! What a piece of trash totally frustrating DISGRACE

Hi Andy, we're very sorry you lost your sessions. Version 1.1.1, now on the App Store, fixes many crashes and backs every session up to your account, so a reinstall no longer wipes them. Sessions on your chronograph (it keeps the last 50) sync again after you sign in and connect. Please update; if anything is missing, email contact@athlonoptics.com.
Was working well, sync is broken
Update: well I gave up and ordered the Garmin Xero C2. The Athlon hardware and pricing is excellent but this app needs major work. I can’t get data to sync reliably and the app only shows a fraction of the sessions on the chronograph itself. It’s too bad as the device is great. Deleting, re-pairing, syncing, nothing gets all my data from device to phone. Really frustrating. Please have the dev team fix syncing if you want this to succeed.
Original:
I was initially impressed with the chronograph and app and everything worked well. Lately when I
Connect to the chrono it shows none of my history and only a bit of my current session. When I get home some of my history appears in the app but much is missing and sync button doesnt change anything. Deleting and readding the chrono from the app worked once but gets to be annoying. Might have to look at the Garmin if this doesn’t improve.

Hi Taran, sorry syncing let you down. Syncing was our biggest problem, and version 1.1.1, now on the App Store rebuilds it: the app reconnects by itself, pulls in every session the chronograph holds and backs them up to your account. If you still have the Rangecraft, please update and try again. Questions: contact@athlonoptics.com.
Crashing
When trying to select rifle and bullet combo app crashes and doesn’t allow login. Tried uninstalling reinstalling same thing happens. Total POS app very disappointed.
NON Functional
This version 1.0.42 DOES NOT work with APPLE DEVICES!!!!. The original version I had after purchase last year did work, but since there is a newer version I upgraded and it is No Longer available on the Apple Store! Appears this version is broken since I am unable to login using the created account. I have done troubleshooting and even deleted the App from all devices and reinstalled. I also RESET my Password (without Special Characters-just Letters and Numbers), since it keeps saying ‘incorrect Password or Email’. The account does send me a link for a Password reset to my Email. The device will still store all captured sessions until the memory is full, but not transfer them until the app lets me login to use and register the device. Maybe someone with a YouTube Channel should do a video for others to be aware? I will have to search for such posting! Thus far support has no solution!

Frustrating to add information
After a day at the range, I’m trying to add notes to my chronograph data. If you leave the text field and come back, it deletes everything you’ve added in so you need to re-enter it. This also happens when entering titles for the different chronograph data samples. Very frustrating to the point I’m going to write things down on paper and not use the app. Horribly designed user interface.

Completely useless
This is what happens when a company wants to be "app enabled" but doesn't care to spend money creating something worthwhile. The app doesn't stay connected, gets hung up on firmware updates, and refuses to sync any data. It's also incredibly poorly designed from a UI standpoint.
The keyboard frequently covers the fields you need to access. The data structure and options would have been outdated in 1985. I spent the time to enter my rifles and all my available ammo profiles, only to realize it binds ammo entries to an individual rifle with no way to duplicate or move an entry. The included database is so embarrassingly small and outdated, I don't know why they bother.
The hardware itself is solid, but I'm returning this for a Garmin C1 Xero entirely because this app is an insult to anyone paying money for this product. Do better, Athlon.

Hi there, thank you for the detailed feedback. Version 1.1.1, now on the App Store, rebuilds the chronograph connection and sync, makes firmware updates more reliable and redesigns many screens. Sharing a bullet across rifles and more bullet data are on our list for upcoming updates. If you try it again, we'd like to hear: contact@athlonoptics.com.
Turn Bluetooth “ON” error UPDATE.
Well, I was finally able to get my Rangecraft Velocity Pro connected. It seemed I tried everything, but I think it was a setting on my phone. I was making so many setting changes and doing hard reboots.
After I was successful connecting the rest was rather easy. Updated firmware, created more gun and ammo profiles, etc. I also watched a good YouTube video from Athlon showing additional features and how to make app changes.
I am very happy with the chrono and app at this time. I only wish they had a Vortex Crossfire scope BDC reticle listed, but it is a low cost scope. Sooo, 1star to 5stars.

Third time back to update this review. I was just trying to export my data into a spreadsheet when the app on my phone crashed. When I reopened it all my chronograph data for the day except for one entry was gone. Thankfully, I hadn’t formatted the memory on the chronograph yet so no problem right? Think again. The app and the chronograph will not sync the data that was lost. $200 of ammo used for velocity data and I have nothing to show for it at the end of the day. Thanks for nothing Athlon. The more I use this app, the more I wish I got a Garmin.

Complexed and buggy
I thought getting a higher priced Chronograph was supposed to mean less hassle getting the data when it matters. All I have found is app crashes when accessing it
If you want to get the best out of your chronograph and your an airgun user, be prepared to research the hell out of each pellet to get ballistic Coefficient then figure out the length plus the fps of said pellet before you have shot it through your rifle. The G1 and G7 profiles are not suitable for airguns. For a sub £400 Chrono I expected more. Disappointing does not cover it

Sucks
Terrible ap, made by a 13 year old. Can’t even create an account
Won’t open
Still won’t open
Awesome Chrono
The Chrono is great, getting it connected takes a little effort but seems to be working well!
Character limits
Please remove the character limits on rifle and bullet profiles, it’s currently very short and cumbersome to come up with abbreviations.
Please also add an option to view the sound barrier on the dope chart.

Not consistent
So I have been to range a few times and this app does not pull all of your shots from the device itself. Athlon does not put any effort into fixing this issue it seems. They need to look at the Caldwell app and take some notes that thing is flawless. For that I would not recommend buying a range craft to anyone.

Hi there, sorry the app missed shots and sessions. We rebuilt the session sync in version 1.1.1, now on the App Store: it pulls in every session the chronograph holds and backs them up to your account. Please update and try again. If anything is still missing, email contact@athlonoptics.com.
Great update
Great ballistics solution! While the app did have issues with pairing to devices, these seem to be resolved!
Will not sync sessions
The hardware works fine for the most part, but the app will not sync any sessions to my phone making it useless
May 2026: certified disaster
First the hardware seems solid. The app seemed to track all the shots accurately as i could determine and despite the quirks (annoying but live-able), exporting data out is where it fails. I can only see 4 of 6 sessions on iPhone (was showing all of them earlier). So when I export to excel I don’t have two sessions.
I synced to ipad, saw all six sessions, but once exported, all had same session name, cartridge, projectile grain weight and other variables!
To figure out, I was fortunate as i was also plotting the grouping separately on graph paper and wrote session start time on each load so i could reconcile. I looked at session time and shot count, then and figured it out. All the session names, the notes section were reverted. Even syncing with iPad it was not there. Added hours to post shooting reconciliation. I didn’t appreciate if i had not been taking paper notes, that i may had had to reshoot $250 in ammo if I couldn’t disentangle this mess

Hi there, sorry for the extra hours this cost you. Version 1.1.1, now on the App Store, rebuilds session sync and backup, so every session comes over and keeps its own name, notes and details on each device. Please update and check again. If an export still looks wrong, email contact@athlonoptics.com so we can reproduce it.
Weak
The Athlon ballistic light app is very weak. I could not get my phone to receive the data from the chronograph, even though it was paired on both devices.
Update as of 11May26: it paired with the phone and updated the firmware with no issues. Will try it out soon.
