Just One rests on a simple idea: each day, you choose ONE thing that truly deserves your attention. Not twenty-five tasks, not a list that keeps growing, not guilt at bedtime. One priority, one decision, one outcome.

HOW IT WORKS

In the morning, you write down your priority for the day. In the evening, you mark it: done, or not today. That's it. The app tracks your streak of successful days and shows how consistent you have been over time.

Until you mark it, your priority stays editable. Once marked, it locks: the day is closed, and tomorrow you start from a blank page.

WHAT YOU GET

• Today — your priority for the day, front and center, and nothing else
• History — a monthly calendar where every day carries its outcome
• Stats — current streak, personal best, success rate, activity over the last 7 or 30 days
• Daily reminder — one notification a day, at the time you choose
• Light and dark themes that follow your phone automatically
• English and French

YOUR DATA STAYS WITH YOU

Just One asks for no account, no sign-up, no email address. Everything is stored on your phone and nothing is sent online. No ads, no trackers, no behavioral analytics.

You can export all of your data as JSON whenever you want, and delete everything in two taps.

WHO IT IS FOR

For anyone who has tried task managers and drowned in them. For anyone who wants to move forward without a dashboard. For anyone who would rather finish one thing than start ten.

Consistency matters more than intensity. ## Rankings - #3,268,069 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.READ_APP_BADGE` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.SYSTEM_ALERT_WINDOW` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `com.anddoes.launcher.permission.UPDATE_COUNT` - `com.android.vending.CHECK_LICENSE` - `com.google.android.c2dm.permission.RECEIVE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.htc.launcher.permission.READ_SETTINGS` - `com.htc.launcher.permission.UPDATE_SHORTCUT` - `com.huawei.android.launcher.permission.CHANGE_BADGE` - `com.huawei.android.launcher.permission.READ_SETTINGS` - `com.huawei.android.launcher.permission.WRITE_SETTINGS` - `com.majeur.launcher.permission.UPDATE_BADGE` - `com.oppo.launcher.permission.READ_SETTINGS` - `com.oppo.launcher.permission.WRITE_SETTINGS` - `com.sec.android.provider.badge.permission.READ` - `com.sec.android.provider.badge.permission.WRITE` - `com.sonyericsson.home.permission.BROADCAST_BADGE` - `com.sonymobile.home.permission.PROVIDER_INSERT_BADGE` - `io.nefa.justone.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `me.everything.badger.permission.BADGE_COUNT_READ` - `me.everything.badger.permission.BADGE_COUNT_WRITE` ## Similar extensions and apps - [One Thing - Daily Focus](https://chrome-stats.com/d/com.purplebus.onething) — 654 users - [One Thing Today](https://chrome-stats.com/d/com.elaine.onethingtoday) — 6 users - [One Thing: Daily Focus Timer](https://chrome-stats.com/d/com.flyinfinity.onething) — 14 users - [FocusOne: Daily Goal Planner](https://chrome-stats.com/d/com.appmaven.focusone) — 30 users - [Onely: One Thing Done Daily](https://chrome-stats.com/d/space.manus.onely) — 18 users - [One Goal](https://chrome-stats.com/d/com.onegoal.app) — 2 users - [Today: One List, This Day Only](https://chrome-stats.com/d/com.naveensingh.today) — 51 users - [One Done - Daily Focus App](https://chrome-stats.com/d/com.onething.done) — 804 users - [Wonday: Focus & One Goal a Day](https://chrome-stats.com/d/one.wonday.android) — 36 users - [OneThingy](https://chrome-stats.com/d/app.replit.onething) — 3 users - [One Priority - Founder Focus](https://chrome-stats.com/d/dev.apptube.the.one.thing) — 9 users - [Today One - One Goal Per Day](https://chrome-stats.com/d/io.mayjune.todayone) — 25 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/io.nefa.justone)
