Built for daily practice

Everything PrepGraph does, made for your phone

A tutor you talk to

Voice-first sessions that explain, ask, and adapt — like a call with a patient tutor who never runs out of time.

A whiteboard that draws along

Diagrams and worked steps appear in sync with the explanation, so you see each idea — not just hear it.

Practice aimed at your gaps

Every session starts from what you are missing. PrepGraph diagnoses weak spots and fixes them one by one.

Synced with the web

One account everywhere. Start on your phone, review on your laptop — progress, streaks, and reports carry over.

  2. Open the downloaded file

    Open it from your browser’s downloads bar, your notifications, or the Files app.

Questions, answered

Is it safe to install an APK from your website?

Yes. Every build is signed with PrepGraph’s release key, and the SHA-256 checksum published above lets you verify your download byte-for-byte. To stay safe, only ever download PrepGraph from prepgraph.com.

Why is the app not on Google Play yet?

The Google Play listing is in the works. Until it goes live, we publish the same signed release build here for direct download.

Does the app cost anything?

No — the download is free and works with the same free plan as the web, no credit card needed. Paid plans unlock more, exactly as they do on the web.

Which devices are supported?

Any phone or tablet running Android 8.0 or later.

How do I update the app?

Come back to this page and install the newest version straight over the old one. Your account, progress, and streaks are untouched.

Is there an iPhone app?

Not yet — iOS is in development. In the meantime, PrepGraph works in the browser on iPhone and iPad.

Ready when you are.

Free to download. Free plan to start. Sign in and your tutor picks up right where you left off.
