Not sure? Start with the browser version — zero setup. You can switch to the desktop app anytime. Same account, same questions.

What if something restarts during the test?

Your remaining questions are safe. Every purchase comes with a short redeem code (shown on your confirmation page, in your email, and on your phone after activation). If the desktop app or phone restarts mid-test, just open a fresh phone page, tap "Have a redeem code?", and paste — your remaining questions follow the code, not the session. On the same phone, this re-attach usually happens automatically with no typing.
