Cozi — Habit Tracker & Planner

Cozi is a calm day planner: tasks with a focus timer, habits that fit themselves into your day, a calendar with reminders, and notes that work like a chat with yourself. Everything works without the internet and without an account, and your data stays on your phone. Tasks with a focus timer
A simple list of what matters today. Break a task into subtasks, give it a type such as Work or Study, and start the focus timer with one tap. Cozi remembers how much time each task really took. Forgot to start the timer? Add the session afterwards.

Day Rhythm
In the morning, mark when you woke up and when you plan to go to bed, and Cozi spreads your habits across the day: water, exercise, vitamins, a walk, reading. Anchor a habit to the clock or to your wake-up time and choose its days of the week. If the day goes off plan, Cozi rebalances the remaining habits into free gaps and moves what doesn't fit to tomorrow. Reminders arrive as notifications, and you can tap Done or Postpone right from the notification shade. Half an hour before bedtime, Cozi reminds you it's time to wind down.

Calendar
A month view plus today's and upcoming events. An event can span several days at once, like a vacation. A reminder one day before is added automatically, and you can add more: 5 minutes, an hour, or any time you choose. Reminders arrive even when the app is closed.

Notes that work like a chat
A conversation with yourself, just like in a familiar messenger: quoted replies, pinned messages, editing, multi-select and search across your entire history with a jump to the right note. Attach photos, videos and files, and record voice notes. Keep separate note profiles for work and personal.

Statistics
See where your time goes: focus time by task type for 7, 14 or 30 days, plus a history of sessions and completed tasks.

Together with your computer
Cozi is also available for Windows in the Microsoft Store under the same name. Plan your week and keep notes on the big screen at your desk, while your phone stays with you to remind you of habits, show the day's plan and capture a thought or a photo on the go.
Sync runs directly over Wi-Fi, with no internet and no cloud. On the computer, open Sync → Show code, then enter the 6-digit code or scan the QR code on your phone. Data merges both ways: new items are added, changes are updated, nothing is lost. If something goes wrong, you can undo a sync within 5 minutes.

Private by design
• No sign-up and no account.
• No ads, analytics or trackers.
• Your data stays on your device — Cozi has no servers for it to pass through.
• PIN lock and fingerprint or face unlock.
• Back up your tasks, habits, events and notes to a file and restore them on this or another device.
