What does it cost?
The app is free and the first 10 questions of every qualification are free. Full questions and mock exams are a one-time in-app purchase per qualification, not a subscription. See the purchase screen for prices.
Is there an Android version?
Yes. It is on Google Play (since October 22, 2026) with the same 49 exams across 34 qualifications. There is no account, so purchases do not carry over between iPhone and Android.
Do I need an account?
No.
Does it need a connection?
Most questions download when you open a qualification. The first 10 work offline.
Is it an official app?
No. It is not an official app of any exam body and does not guarantee a pass.
