Download for Android
A calibrated G7 ballistic solver paired with a per-rifle data system — installed straight from us, no app store required.
Download APK (v0.03.32)Free 31-day trial — nothing is charged up front.
Built for the field — Android only
These run on the phone’s camera, Bluetooth, and sensors, so they live in the native Android app — not the web version.
Kestrel weather meter
Pair a Kestrel over Bluetooth and pull live wind, temperature, pressure, and density altitude straight into your solve — no hand-typing conditions.
Camera group measurement
Photograph your target and the app measures the group for you — extreme spread or mean radius in MOA — and saves it to the session.
Live azimuth & incline
Use the camera and the phone’s sensors to capture look angle and incline for steep uphill and downhill shots.
Automatic position
Latitude and altitude come straight from the phone, so Coriolis drift and air density are dialed in without typing a thing.
Works fully offline
Everything runs with no signal at the range. Your firearms, loads, and sessions sync back to your account the moment you’re online again.
Installing the app
Because Apex installs directly (not through the Play Store), Android asks you to confirm the install once. It takes about a minute:
- Tap Download APK above. Your browser may warn that this type of file “can harm your device” — that’s the standard message Android shows for any app installed from outside the Play Store. Tap Download anyway (or OK).
- Open the downloaded file — tap the download notification, or find apex-ballistics-v0.03.32.apk in your Downloads / Files app and tap it.
- If Android says installing from this source isn’t allowed yet, tap Settings, turn on Allow from this source, then press Back.
- Tap Install, then Open. Sign in with your Apex account — or start your free 31-day trial.
Installed an earlier test build from Google Play? Uninstall it first, then install this one. The direct-download version is signed by us rather than by Google, so it won’t update over a Play-installed copy. Your firearms, loads, and sessions are safe in your account and re-sync the moment you sign back in.
Subscriptions
Apex subscriptions are handled securely through PayPal — pay by card or PayPal balance, no Google account required. When you subscribe, a checkout page opens in your browser; finish there and return to the app. The same subscription works across the Android app, the web app, and the mobile web app.
On iPhone or a computer?
There’s no iOS app yet, but the full platform runs in your browser — same account, same data, nothing to install. Open app.apexballistics.com and sign in.
Updating later
When a new version is out, come back to this page and download it again — installing over your current app keeps everything, since your data lives in your account, not the app file. We’ll note the latest version number right on the download button above.
