User Reviews

AB Quantum is a powerful ballistic app with advanced modeling and real-time analysis, and strong hardware integration (Kestrel, Garmin, wearables) that makes it especially useful for professionals and long-range shooters. However, it faces stability and reliability issues (crashes, freezes, wind data glitches) and usability complaints about a steep learning curve and a less friendly new interface. Repeatedly cited gaps include Apple Watch HUD, remote waypoint support, vortex scope profiles, and some licensing/paywall changes, along with mixed support experiences.

Pros

Powerful, feature-rich ballistic solver with advanced models (Monte Carlo WEZ, radar-verified drag) and real-time expert analysis (Spotter).
Strong hardware integration: load/sync profiles from Kestrel, sync with Garmin watches, and display firing solutions on wearables.
Pro-level usefulness for instructors and long-range shooters; accurate at extreme distances and across calibers; widely applicable.
Clean, modern interface and strong overall capabilities that many users compare favorably to competitors.

Cons

Stability and reliability issues: crashes after iOS updates, random freezes, and intermittent comms/wind data problems with Kestrel.
Usability concerns: steep learning curve and some users finding the new interface less friendly than the old version.

Recent reviews

The app itself is very good. In fact, my only challenge is that it doesn’t seem to have any Minox reticules in the library. I also know the Nikon scopes are older, but all of those in my extended family are still in use. I did the paid upgrade and will renew if AB Quantum get all the major scope manufacturer’s reticules in the library

I just purchased the Pro mode bcz I have both Kestrel WEZ and calypso, and app was constantly switching between the pro and ultralite modes. Every time it switched my targets would get messed up to default. After using pro version for a while, the app started crashing. Now it just stays on the AB Quantum startup screen with the black background and never loads any further. I have already tried rebooting my iPad, but it did not help. At this point, the only thing I can think of is deleting and reinstalling the app. However, I am concerned that if I delete the app, I may lose all of my data, including profiles, targets, sectors, and other information I have already entered. Could you please advise what I should do? Is there a way to recover the app without losing my data?
