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.

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 install PrepGraph from Google Play or from prepgraph.com.

Is PrepGraph on Google Play?

Yes. Install it from Google Play, which keeps it updated for you. Google Play currently serves version 1.9.4; the newest build, version 1.12.0, is also published here as a signed APK until the Play listing catches up.

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?

Google Play updates it for you. If you installed the APK instead, 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.
