Installation & access
PrepAI runs in any modern browser with nothing to install, and can optionally be added to your home screen as a Progressive Web App (PWA) or installed as a native Android app. There is no paid download — the free tier is available the moment you sign in.
1. Use it in a browser (fastest)
Open interviewpai.aoneahsan.com in Chrome, Edge, Firefox, Safari, or any current browser. The full app — practice drills, mock interviews, peer reviews, dashboard, and tools — works directly in the tab. The 50+ developer tools are usable without even signing in; signing in unlocks progress tracking, mock interviews, and reviews.
Recommended browsers: the latest version of Chrome, Edge, Firefox, or Safari on desktop, or Chrome/Safari on mobile. PrepAI is responsive from 320px phones up to wide desktops.
2. Install it as a Progressive Web App
Installing the PWA gives you an app icon, a standalone window (no browser chrome), and offline access to already-loaded content.
- Desktop Chrome/Edge: click the install icon in the address bar, or open the browser menu and choose Install PrepAI.
- Android Chrome: open the menu (⋮) and tap Add to Home screen / Install app.
- iOS Safari: tap the Share button, then Add to Home Screen.
See the dedicated guide: Install PrepAI as a PWA.
3. Get the Android app
The native Android build is available on Google Play:
Get PrepAI on Google Play — package id
com.aoneahsan.interviewpai.
The Android app is built with Capacitor and wraps the same web experience with native niceties (splash screen, status-bar theming, haptics, native share sheet, and in-app review prompts).
4. iOS
PrepAI is built cross-platform with Capacitor, so an iOS build is technically supported. As of this writing the iOS app is not yet published to the App Store — iPhone and iPad users should use the web app or add it to the Home Screen from Safari (step 2 above), which gives a near-native experience.
