Do One Thing. Earn Your Screen Time.

Most screen time apps just block your phone. OneThing is different — it makes you earn it.

Pick one meaningful habit. Prove you did it. Your apps unlock when you're done. It's that simple.

OneThing is the focus app built around one powerful idea: replace mindless scrolling with one real-world activity every day. Over 21 days, you'll build the habit of putting your phone down and doing what actually matters.

How It Works

Choose your One Thing — gym, reading, deep work, meditation, or anything that matters to you
Snap a photo to prove you're doing it (verified by AI)
Stay focused while your distraction apps are locked
Finish your session and earn your screen time back
It's not about willpower. It's about building a system that rewards real action.

Key Features

AI Photo Verification Snap a photo of your activity and our AI confirms you're actually doing it. No more lying to yourself. Stay honest, stay accountable.

Earn Your Screen Time Your distraction apps stay locked until you complete your daily habit. Do the work first, scroll later.

Smart Schedules Set recurring focus windows for work, study, bedtime, or family time. Build a daily routine that sticks.

Focus Modes Create custom blocking profiles for different parts of your day — deep work, study, wind-down — each with their own app lists and durations.

Daily App Limits Set time caps on social media, games, or any app. When you hit your limit, the apps are blocked until tomorrow.

Streaks & Progress Build your streak day by day. Track your focus hours, screen time trends, pickups, and habit completions on a visual dashboard.

Emergency Unlock Life happens. You get 3 emergency unlocks per week if you really need access — but you'll think twice before using one.

Screen Time Tracking See exactly where your time goes. Track daily usage by app, monitor pickups, and watch your screen time drop week over week.

The 21-Day Challenge

The average person spends over 5 hours a day on their phone. Research shows it takes around 21 days to reshape a habit. OneThing gives you a structured, science-backed path to cut your screen time in half — by replacing it with something you actually care about.

Private and Secure

Your data stays on your device. We don't track what you do in your apps — only usage time. No accounts, no cloud sync, no data collection. Your habits are your business.

About AccessibilityService API Permission

On devices running Android 14 and above, OneThing uses the AccessibilityService API to detect when blocked apps are opened during focus sessions, enabling a blocking screen to help you stay on track and limit your screen time.
