FAQ

What is a credit?

Opening a new problem uses one credit. Reopening a problem you saved doesn't use another one.

What happens after the first 5 exercises?

You sign up with no credit card and get your first 5 exercises free. If you want to keep going, you choose a plan inside the app.

Just the answer, or the method too?

The whole method — every equation and every step is written out, not just the result.

Can I solve it myself and get checked?

Yes. You enter every value yourself, and BST confirms or corrects you as you go.

Does it work on a phone?

Yes — in the browser, nothing to install.
