Common questions

Do I need an account? No. The app works without sign-up.

Where are my records kept? On our server, in a private space for your phone. The privacy policy has the whole picture.

Is there an Android version? Yes. Download it from the app page. We've submitted it to Google Play and we're still waiting to hear back.

Something looks wrong in a calculation. Tell us. Precision is the whole point. Email the details and we'll look into it.

Can I request a feature? Absolutely. A lot of the app came from shooter feedback.
