Premium Test Series App

I want to launch a modern, minimalist mobile app on both iOS and Android that lets me sell and manage test-series for students while also sharing study material such as PDFs. The core flow is straightforward: learners sign up with phone-number + OTP, pick a test, and start practicing.

Two distinct test modes are essential.
• Practice Mode – students can retake these tests as many times as they like.
• Live Mode – the paper opens for everyone at the same scheduled time and each student gets only one attempt.

Each account must work on a maximum of two devices to discourage sharing. The overall interface should look premium, load fast, and remain completely glitch-free. After the first release I will need ongoing support for updates, bug fixes, and minor feature refinements.

Key deliverables:
1. iOS and Android apps built around the two test modes, study-material section (PDF viewer / downloader), and 2-device restriction logic.
2. Clean, minimalist UI/UX consistent across both platforms.
3. Secure phone-number + OTP authentication with an eye toward scalability.
4. Post-launch maintenance plan.

If you have experience delivering smooth cross-platform education apps and can back it up with reliable after-care, let’s talk.
