Every topic taught out loud, coded together, tested until it sticks.

Recomposed is a working tutor for Android interviews: lessons read aloud word by word with a voice tutor on call, pair-programming tasks with a coach reading your Kotlin, code-review drills graded by a tech lead, and tests that bring back whatever you miss.

One topic, four passes.

Reading about ANRs doesn't survive a follow-up question. Each topic runs the same loop until it does.

01 Hear it — A guided lesson read aloud word by word, with a voice tutor one tap away.
02 Build it — Pair tasks in real Kotlin, with a coach that watches your screen and your tests.
03 Review it — You review flawed, realistic code — a tech lead grades what you caught.
04 Prove it — Timed tests per topic. Anything you miss returns on a spaced schedule.

Lessons read aloud, word by word.

Every topic has a guided lesson narrated word by word, the spoken word highlighted as it goes — reasoning at speaking pace, the pace you'll have to produce it at in an interview.

Follow the highlighted word as it's read — or mute it and just read.
Grounded in the official docs — every lesson cites its sources.
Stuck? “Talk to tutor” opens a voice call about the exact chunk on screen.

Write real Kotlin with a coach on the call.

Each topic ships hands-on tasks with real tests. Share your screen and the coach sees your code as you type — it nudges, it doesn't dictate.

Tasks graded by real test suites, not vibes.
The coach teaches the concept, then makes you defend the fix.
Voice or typed — the session works either way.

You do the reviewing.

Review drills hand you flawed, realistic Android code and you pin comments to lines, like a real PR. Then the tech lead grades your review — what you caught, what you missed, and why it matters.

Real smells: races, leaked scopes, main-thread I/O, lifecycle traps.
Graded per issue — found, partial, or missed — with a score for the review.

Miss it once, see it again. On schedule.

Timed tests close every topic — 14 questions each, fresh random draw per attempt. Every miss lands in a Leitner queue and comes back right before you'd forget it.

Every answer explained — including the wrong ones.
A readiness score per topic that only moves when you prove it.

Then get grilled.

A voice mock interviewer that asks real follow-ups, presses on hand-waving, and scores you on six dimensions afterward — with the gaps routed back into your review queue.
