Coriolis on iPhone

The beta, and how to get on it

The short version

Coriolis Precision is being built for iPhone and iPad. It is the same app as the Android one - the same solver, the same catalogue, the same record - not a cut-down copy. It is not open yet. Tell us you want in and you will get the invitation the day it opens.

How TestFlight works

  1. Install TestFlight from the App Store. It is Apple's own app for testing.
  2. Open the invitation. TestFlight installs Coriolis alongside anything else on your phone.
  3. Shoot with it. Updates arrive the same way, and you can leave at any time by deleting it.

You need iOS 15 or newer. Anything from an iPhone 6s onwards will run it.

Coming with the next builds

The iPhone build carries the whole app: the ballistic solution, the armoury and certificate record, ammunition and load development, sessions, printable targets and every report. The camera is in - scanning a target, a barcode or a handover code, and capturing the firing point from the phone's own compass, tilt and position. So is moving your record between phones by backup, and attaching photographs and paperwork. Arriving as the beta runs:

  • Subscriptions, which is why the beta asks you for nothing.
  • Bluetooth kit, and the Garmin watch link.

Each is being finished to the same standard as the rest rather than rushed in, and every screen says where it is up to rather than failing quietly.

What we want from you

Tell us what breaks, what reads wrong, and what you expected to happen instead. There is a Feedback option inside the app, and everything anybody sends is answered on You said, we did.

No analytics, no tracking, no online account needed. Your firearms and your record stay on your phone - the beta changes nothing about that. See the privacy policy.

The reward programme

Every box you scan feeds the shared ammunition catalogue: the barcode, the load, the maker's own figures. It is anonymous, and it earns you a point for every barcode nobody has sent before - points that come off next year's subscription. The odd ones, the imports and the shop brands are where the gaps are, and beta testers are first in line for them. How the reward programme works →

Scanning needs the camera, so on iPhone it arrives with the camera work. On Android it is there today - and a barcode scanned on either phone counts the same.
