The Web App

The web app is the same calculator as the phone app, signed in to the same account. Two things about it are deliberately different, and both are worth knowing before you set anything up in a browser.

The ballistics are solved on our servers

Nothing is computed in the browser. Each solve is sent to our server, which is why the web app needs an account even in free mode, and why the number of requests you can make is limited. The trajectory you get back is identical to the one the phone app produces.

The kit libraries stay on the server

The projectile, scope and reticle libraries are our own compiled reference data. In a browser they are never handed over in bulk, on any plan. What a picker in the web app lists is:

• The generic entries. Four generic scopes and three generic reticles, written from scratch by us. They are enough to configure a real optic by hand: set the magnification range, focal plane and click values to match your own scope and the maths is the same.
• Anything you have added yourself. Your own bullets, scopes and drag curves work in full in the browser, exactly as they do on a phone.
• Anything your own saved data already uses. If a profile, scope or load of yours names a library entry, that one entry is fetched for you.

There is no generic bullet, because a projectile is its manufacturer’s measured numbers: there is nothing brand-neutral to offer. So the bullet picker in a browser holds your own entries and the ones your saved profiles and loads already use.

Kit you set up on a phone comes with you

This is the part that matters in practice. A rifle built in the phone app arrives in the browser complete:

• The bullet is stored on the profile itself, with its weight, calibre, BC and drag model, so it solves in a browser whether or not the library is reachable.
• A saved scope carries all of its own settings, so magnification, focal plane, click values and tracking corrections all come across.
• The reticle is fetched for you when you open the profile, because your own scope names it.

So the way to use a library bullet or a catalogue scope on the web is to pick it once in the phone app. It syncs with your profile and it is there when you sign in.

For this to happen your data has to reach the browser, which means cloud sync: see Backup, Sync & Account.

Fair use of the libraries

The libraries are licensed for your own shooting inside the app. That does not license a copy to pass on: please don’t bulk-download, scrape, republish or redistribute them, or use them to populate another product.
