Frequently asked
Does the app cost anything?
No. All questions, the mock exam and every worked solution are free. There is no advertising either.
Does it work offline?
Partly. The first topic of every subject is included in the app and works offline. The rest of the question bank is served from our server and needs an account and a connection.
Do I have to create an account?
Not for the first topics. An account is needed for the rest of the question bank, XP, the daily streak and the mock exams. You can sign up with a login and password or with an Apple ID; your progress then follows you to a new phone.
I changed my phone and lost my progress
Progress only moves between devices if an account was linked. If the old phone had no account connected, the data stayed there. On the new phone, sign in with the same Apple ID or Telegram account and your progress will come back.
Why is «Official structure» shown only for Mathematics?
Because the official specification document is currently available only for Mathematics. For the other subjects the structure is general, and the app says so openly. Presenting a guessed structure as «official» would mislead you — so it is not done.
I found a mistake in a question
Please write to us — send the question text or a screenshot. The question bank passes three review gates, but a mistake can still slip through. Confirmed errors are fixed in the next release.
Why is the leaderboard empty?
Because there are not enough users yet. It would have been easy to fill it with invented names — that was deliberately not done.
I want my data deleted
Deleting the app from your phone removes everything stored on the device. To erase the account and the cloud record as well, use Profile → Delete account inside the app — one step, immediate. Details: privacy policy.
