Description
Stop multitasking. Start finishing.
OneThing is a beautiful focus timer and app blocker that helps you give one task your whole attention — for ten minutes or two hours, undivided.
★ Custom focus timer (10 min – 2 hours) ★ App blocker that silences distractions mid-session ★ Do Not Disturb automation ★ Streaks, heatmap, and a weekly review ★ 100% offline — no account, no cloud, no ads, no subscription
WHY OneThing
Most productivity apps add noise. Notifications, leaderboards, streaks designed to shame you, dark patterns. OneThing strips all of that out.
You open the app. You name the one thing you're going to do. You pick a duration. OneThing silences the rest of your phone for that window — and then it gets out of your way.
FEATURES
▶ Focus Timer Custom durations from 10 minutes to 2 hours. A gentle chime when you finish.
▶ App Blocker Pick the apps that steal your time. If you wander off during a session, OneThing pulls you back to the timer.
▶ Do Not Disturb Notifications go silent for the length of your session, then restore automatically. No more "just checking" the screen at the wrong moment.
▶ Streaks That Don't Punish You Build a daily focus streak based on consistent practice, not perfection. Miss a day? Pick up where you left off.
▶ Year-At-A-Glance Heatmap A GitHub-style grid of every focused minute. Beautiful, motivating, and 100% private to your device.
▶ Weekly Review See exactly what you focused on this week — by category, by day, by streak. No spreadsheets, no charts you can't read.
▶ Five Time-of-Day Themes Dawn. Morning. Afternoon. Evening. Night. OneThing shifts gently with your day, so the app at 6 AM looks nothing like the app at 11 PM.
▶ Distraction Tracking See which apps eat your hours and how that's changing week over week. Awareness is the first move.
