The all-in-one calendar
Calengaroo is a minimal calendar with a live timer built in. Your tasks, notes and money sit right next to your events. It looks and works the same on your phone and your computer, even offline.
Free. No account needed.
How the timer works
- 1
Type what you are doing
Like “Design review” or “Take out the trash”.
- 2
Press start
A live event appears on your calendar and grows while you work.
- 3
Press stop
It stays as a normal event, so your calendar shows what really happened.
Made for ADHD minds, and anyone who hates extra steps
I have ADHD, and that is why I built Calengaroo: everything in one place, as few taps as possible, and nothing in the way. A minimal app that stays quiet until you need it.
Saves by itself
No Save button. Every change is kept as you type.
Delete in one tap
No “Are you sure?” box. Changed your mind? Press Undo.
Drag and drop everywhere
Move events on the calendar, tasks in your lists and notes into folders.
All in one place
Calendar, timer, tasks, notes and money together, so nothing gets lost between apps.
Minimal by design
A clean, quiet screen with only what you need, and no clutter.
One tap to start
Start the timer from anywhere, then get back to what you were doing.
Every view you need
Day, three days, week, year and list. Drag an event to move it, pull an edge to change its length, pinch to zoom the day. It works the same with a finger or a mouse.
Tasks that know your calendar
Lists, subtasks, stars, dates and deadlines. Give a task a date and it shows up on your calendar too.
See where your money goes
Write down what each event cost, in as many wallets as you like (cash, card, savings), each with its own currency. Calengaroo shows what you spent, what it should have cost, and the difference.
A Notion-style editor in every event, task and note
Every event, task and note has a full rich-text description. Type / and add what you need, for example:
- Checklists
- Numbered and bullet lists
- Headings and quotes
- Tables
- Photos and images
- Videos
- Voice recordings
- Timestamps
- Expenses and income
- Links to other items
And more: dividers, find and replace, a full-screen mode, voice commands while you dictate, and a camera built in.
Money you write in the text is real: it shows up in your budget.
Notes in folders
Put notes in folders inside folders, give each one a color, and drag them where you want. Every photo you add also lands in one gallery.
And a lot more
Works offline
After your first visit, it works with no internet at all. Everything is saved on your device first, so there is no waiting.
Fast on any phone
Made to stay smooth on old and cheap phones, even with thousands of events.
Same app everywhere
Your phone, tablet and computer show the same app, with the same buttons and the same gestures. Learn it once.
Never locked in
Export to .ics for Google Calendar, Outlook or Apple Calendar, or save a full backup as a .zip file.
Find anything
Search every event, task, note and expense at once, even with a typo.
English and French
The whole app speaks both, and each wallet can use its own currency.
