Practice

Reading an answer and giving one are different skills. Practice here means saying the answer, getting it scored, and then taking the follow-up.

iOS and Android: Interview Runtime

Interview Runtime is one book per platform plus a practice dashboard. It starts with a brief and a baseline, builds a 7, 14 or 30-day route, and includes 12 simulations. Each answer is scored against a written rubric and followed by the question an interviewer would ask next. $59 for one platform, $89 for both.

Flutter and React Native

There is no interactive practice for these platforms yet. The question banks (Flutter, React Native) are the honest starting point: read the question, answer it out loud before you read the answer, then compare.

Live coding without a partner

Record yourself solving a small problem with the screen shared to nobody, narrating as if someone were watching. Watch it back once and count the silences longer than ten seconds. That count is the number to reduce. The live coding guide explains what to say during those silences.
