Tasks you actually finish

Lock In brings tasks, projects, a calendar and focus mode into one app. Write the way you think — “call mom tomorrow at 6pm” — and the date and time fill themselves in. Everything syncs between your phone and computer.

Free for 7 days · works offline · syncs across devices

Everything to get things done

Nothing extra: write it down, plan it, focus — and check it off.

Write the way you think

call mom tomorrow at 6pm #family — the date, time and tag are picked up on their own. Works in English and Russian.

Your day and week at a glance

Today, Upcoming and the calendar. Drag a task to another day, and anything without a date waits in Someday.

One-task mode

Only the current task and a timer on screen: by estimate, for 25 minutes or a stopwatch. Subtasks always at hand.

Reminders on time

At the due time or ahead — 5 minutes, an hour or a day before. They arrive even when the app is closed.

Widget and Share

Your next task on the Android home screen — check it off with one tap. A link from any app becomes a task instantly.

The same everywhere

Phone, computer and browser sync automatically. Everything works offline, and changes catch up later.

Passcode

Optionally lock the app with a four-digit code. The code is stored only on your device.

Search and bulk actions

Ctrl+K finds any task or note. Select several tasks and move or complete them all at once.

Questions

How much does it cost?

Every new user gets 7 days free, then it’s 100 ₽ a month. Subscribe now and this price stays yours for as long as you use the app.

Where are my tasks stored?

On your device, so everything works offline, and on our server in Russia, to sync between devices. We don’t sell or share your data. See the privacy policy for details.

How do I move my tasks to a new device?

Install Lock In and sign in to the same account — your tasks, projects and notes come along by themselves.

Why do Windows or Android show a warning when installing?

That’s how the system treats new apps that aren’t in app stores yet and don’t have a paid publisher signature. The files are downloaded only from this site.

How do I contact you?

Write to lock-in@lock-in-plan.ru or on Telegram @nks_help — we’ll answer.

Installing on Windows

  1. Click “Download” on the Windows card — you get Lock In_…_x64-setup.exe.
  2. If the browser says the file is not commonly downloaded, open downloads, click “…” → “Keep” → “Keep anyway”.
  3. Open the file. If a blue window says “Windows protected your PC”, that is SmartScreen: click “More info”, then “Run anyway”.
  4. Go through the installer — it takes under a minute. Lock In opens by itself.
  5. Sign in. The app lives in the tray next to the clock and offers updates on its own.

SmartScreen warns about every new program with few installs yet. It does not mean anything is wrong with the file: the installer only comes from lock-in-plan.ru.

Installing on Android

  1. Open this page on your phone and tap “Download APK”.
  2. If the browser warns the file may be harmful, tap “Download anyway”.
  3. Open the file from the notification or the Downloads folder.
  4. If the phone says installs from this source are blocked, tap “Settings”, turn on “Allow from this source” and go back.
  5. If Play Protect shows a check (“App not verified” or “Unsafe app”), tap “More details” → “Install anyway”. You can skip sending the app for a scan.
  6. Tap “Install”, then “Open” and sign in. The app offers new versions on its own.

The check appears because Lock In is not on Google Play yet. Xiaomi, Huawei and other phones have a similar security check of their own — you can skip it too.

Installing on iPhone and iPad

  1. Open lock-in-plan.ru/app in Safari. On iOS 16.4 and newer, Chrome or Edge work too.
  2. Tap the Share button — the square with an arrow up (at the bottom or next to the address).
  3. Scroll the menu and choose “Add to Home Screen”.
  4. Tap “Add”. The Lock In icon appears on the screen.
  5. Open Lock In from that icon and sign in.
  6. To get reminders, allow notifications on the first tap (needs iOS 16.4 or newer).

There is no App Store app yet: on iPhone Lock In runs as a web app, with its own icon and window, without the address bar.

Open the web app

Web app

  1. Open lock-in-plan.ru/app in Chrome, Edge, Yandex Browser or Firefox.
  2. Sign in with the same account as on your phone and computer — the same tasks.
  3. Want it in its own window, like a program? In Chrome and Edge click the Install icon at the end of the address bar, or choose ⋮ → “Install Lock In”.
  4. Allow notifications to get reminders.

Nothing to download: the web app is always the latest version.
