Worked previously, but I was hoping to get some use out of the app since I’ll be shooting out to 1,000yds this weekend. Oh well. Edit: I uninstalled then reinstalled the app, and it seems to be working as expected for the moment. ### 4/5 — App won’t open anymore *2026-02-13* I love this app very much but it won’t open for me anymore. It does the initial loading screen and then just closes. Tried deleting and reinstalling, it open the first time but after that it won’t open. I’m on version 5.8 if that’s helpful in any way. Other than this problem I’ve loved the app, just a bummer. ### 3/5 — Constant crashes *2025-12-18, version 5.8* I really enjoy this app but it often crashes and won’t open. Especially in times of need. Please fix this. ### 1/5 — Glitchy *2025-11-03, version 5.8* Kept crashing and wouldn’t open when it counted. Also didn’t have my ammo (federal ascent 155 gr) or my scope. Not a great app imo ### 1/5 — Just crashes *2025-10-23, version 5.8* The app won’t open. Just crashes over again. Had to delete and reinstall but will not work consistently ### 2/5 — Closes randomly *2025-10-22, version 5.8* The app is cool when it works. But it often won’t open when all my other apps will. I have to delete the app and reinstall it from the App Store, Then I have to enter all the info and billets again. I have sent help requests with no answer. ### 1/5 — Nicht mehr nutzbar *2025-10-18* Stürzt beim Start immer ab. ### 1/5 — Missing G7 coefficient *2025-10-14* Two major problems with this app. It crashes on open unless you purchase the subscription. But the bigger problem is that it’s missing the G7 coefficient and only has G1. This app otherwise is probably the best out there in terms of layout and intuitiveness. However, without having G7 and other coefficients to choose this unfortunately renders it useless. I’ll rate 5 stars if these are fixed. ### 1/5 — Needs upgrades *2025-10-14, version 5.8* App works at first open, then crashes after wanting to use again. Needs to be upgraded ### 2/5 — The app quits *2025-10-13, version 5.8* The app works great once initially downloaded, I try to reopen the app and it force quits. I’d have to redownload and re-input data to use the app again. Hopefully there is a fix for this ### 2/5 — Start-Up crash *2025-10-12, version 5.8* Great app. I want to come back and give it 5 starts. Unfortunately, I have to delete and redownload the app every time which causes me to have to redo all the ammo and rifle selections. ### 1/5 — SBC Not completely functional. *2025-10-09* Purchased the app with excitement. Set it up using my specific set up. Worked great and was right on the money where hold or clicks was concerned. When I opened the app later I realized that it wouldn’t open at all. I had to delete it, and then reinstall it. It did not save any of my rifle, scope, or load data. This was a total letdown as I now had to go through inputting all the info again. I reached out to support for help and received nothing. All I can say is don’t waste your time. It’s not functional. Totally bummed. Alan S. ### 1/5 — Constant crashes *2025-09-17, version 5.8* Was a great app, but now it constantly crashes, forcing me to delete and reinstall which makes me lose my saved data. ### 2/5 — Crash *2025-09-15, version 5.8* App is great but after using it a few times I am forced to delete it and download again. The light version does not have this issue and has caused me to get other companies ballistic apps. ## Most critical reviews (10 lowest-rated) ### 1/5 — WTF *2026-05-28, version 5.8* So I pay to get the app only to discover MY scope is “in development “ and not available. Maybe they could have MENTIONED THAT . Pi$$ed off . They better reared it me card. ### 1/5 — Won’t open anymore. *2026-05-16, version 5.8* App is terrific but it doesn’t open anymore. ### 1/5 — App Doesn’t Work *2026-05-06, version 5.8* This app doesn’t not run on the iPhone 17 Pro Max. It quits every time as it is loading up. ### 1/5 — no work to iphone 15 pro max *2026-03-06, version 5.8* no work to iphone 15 pro max ### 1/5 — Crash when you filled all required info *2026-01-23* It won’t open again when everything is filled ### 1/5 — Not working *2025-12-16, version 5.8* The app keeps crashing ### 1/5 — Unusable after the recent iOS versions *2025-12-08* I’ve been using SBC Ballistic Calculator for a long time and it used to work great. Unfortunately, ever since the last couple of iOS updates, the app has become completely unusable. It crashes instantly — it either closes abruptly during use or doesn’t even open at all. With hunting season right around the corner, this has been incredibly frustrating. I tried deleting and reinstalling the app multiple times but the issue still persists. No updates or fixes from the developer in weeks, so I finally had to switch to another ballistic app. Really disappointed to see a once-reliable tool go downhill like this. ### 1/5 — Won’t open *2025-11-21* This appears to be a very good app however, once I set up the rifles and save them, and the app is closed such as when the phone restarts when I go to open the app, it won’t open the icon pops on the screen spins around once and I’m returning to the home screen support has yet to respond to my request for assistance. I have to remove the app from my home screen from the phone and then I have to re-download it but when doing so it tells me I will lose all my data when I re-download the app after deleting it. The app opens, but my data is gone. Also, there is no way to save different rifles with different ammunition types if I save and set up a rifle in 308 and then I create another rifle in 65 Creedmoor the rifle that was set up in 308 is now showing 65 Creedmoor. Is this app supported any longer? ### 1/5 — Was great but crashes on startup *2025-11-19, version 5.8* Have to delete the app and reinstall every week just to use and of course none of the data is saved. ### 1/5 — Sc *2025-11-08, version 5.8* App never works, always have issues trying to open it up ## Most praised reviews (10 highest-rated) ### 5/5 — SBC Ballistics App *2026-08-01* This app is brilliant and so easy to use. If you have bullet data and your scope is listed in the app this will become your favourite shooting app. It shows you what you’ll see through your scope and where to place the target on the reticle image…..ive tested it and it works perfectly. 10 out of 10 👍 ### 5/5 — Spot on *2026-04-04, version 5.8* I got this app while I was at the range. Forgot my IPad with my information on it. Fired two shots with the chronograph. Entered the info and it was spot on the target at 500 yards. Can’t complain for that. Will be keeping it. ### 5/5 — Pretty dang close *2026-01-11, version 5.8* It’s pretty dang close out to a grand. You just kinda have to play with the app some to figure it out then it works nicely. ### 5/5 — Love this app! There isn’t another like it. *2025-11-30, version 5.8* However, it doesn’t open on my new iPhone. Hoping an update comes soon. ### 5/5 — Been great for me *2025-09-24, version 5.8* Iv been using this app for the last year now and it’s been 95% right on for me with all of the information I put in it’d dead on for me ### 5/5 — It’s so useful *2025-09-16, version 5.8* I love this app ### 5/5 — Great *2025-09-09* Had the SBC lite for a long time downloaded this one now I use both to compare back and forth and love being able to have data quick and store hand loads and all the other features been using these two apps for years ### 5/5 — App crashing iOS 18.6.2 *2025-09-05, version 5.8* Love the app but App is failing to open on iOS iOS 18.6.2 ### 5/5 — Super app mit tollen funktionen *2025-07-24* Ich bin Anhänger und für mich ist dir app optimal ### 5/5 — Excellent Dope App *2025-04-14, version 5.8* I am new to long range shooting what I have seen and used with the app it’s great!🤙 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
