A private priority instrument. Choose what deserves today, give it real time, and close the day.
decideone.app · Free, for everyone, with nothing held back · Open source under the MIT licence
- One page, three methods. Top 3 (three things and no fourth), Ivy Lee (six in strict order, each locked until the previous is done) and the Urgent/Important Matrix (classify before writing).
- Time is what you actually spent. Each priority has a stopwatch that counts up from
00:00. The right-hand page shows where the time went, and turning the page closes the day. - Weekly, monthly and yearly views of the same work.
- Your writing stays in this browser. Entries live in local storage. There is no account, no cloud sync and no server copy.
- Live storage is not encrypted. Anyone with access to your unlocked device and browser profile can read it.
- Exports can be.
.vaultfiles use WebCrypto AES-GCM-256 with PBKDF2 key derivation and an HMAC-SHA256 signature, under a passphrase you choose. - The privacy shutter hides the page from the room. It is a screen, not a security boundary, and it says so.
- Anonymous analytics are off. They are compiled out unless a build enables them, and even then nothing is sent until you say yes in Settings.
- Support involves no payment code. Paying happens in your UPI app or on GitHub; the instrument never sees it.
Requires Node 22 or later.

Decide One is free and nothing unlocks by paying. If it has been worth something to you, Menu → Support Decide One offers UPI in India and GitHub Sponsors everywhere else.
Support links appear only when the VITE_SUPPORT_* variables in .env.example are set, so a fork never shows someone else's payment details.
