Questions & answers

Does ErrorBank need an internet connection or an account?

No. ErrorBank works fully offline and has no accounts. Your questions, drawings and statistics are stored only on your device.

Which exams is it for?

ErrorBank is built for students preparing for exams such as the Turkish YKS and LGS, and it works for any subject you study.

How does the review schedule work?

Each question has a mastery target of 1 to 10 correct reviews. Review intervals depend on difficulty, and a missed attempt brings the question back the next day.

Are there subscriptions or in-app purchases?

No. ErrorBank is a one-time purchase on the App Store, with no ads and no in-app purchases.

What happens to my data if I delete the app?

Deleting the app removes all of its data from your device. Export important questions to PDF first if you want to keep them.
