I built an Android study timer with spaced repetition – looking for alpha testers

#android #kotlin #productivity #showdev

The Problem

I was studying for certifications and had two recurring frustrations:

Phone distractions: Every focus app I tried was easy to bypass. Force-quit, PiP mode, or just dismiss the notification.
Forgetting everything: I'd study for hours, then forget the material a week later. Manual review scheduling never stuck.

Iterio – an Android app that combines aggressive focus enforcement with automatic spaced repetition.

App Restriction: Block selected apps during sessions
Normal Lock: Prevent phone unlocking entirely
Complete Lock: Full lockdown including PiP blocking. Your phone becomes a timer and nothing else.

Based on the Ebbinghaus forgetting curve. When you finish studying a topic, Iterio auto-generates review tasks at optimal intervals:

No manual scheduling. The app tells you what to review and when.

Kotlin, Jetpack Compose, Room, Hilt, Material 3, Glance widgets, Google Play Billing

I need people who are actively studying for something—exams, certifications, new skills—and would use a focus timer regularly.

What you get:

Requirements: Android 8.0+

How to join: Send your Gmail address to support-iterio@ks-apps.org — I'll add you to the Google Play alpha test within 24 hours.

Would love feedback from fellow devs!
