One honest day.

Most people don't need another productivity system. They need one day of telling themselves the truth — and then something small to keep them pointed the right way.

One Day walks you through the protocol from Dan Koe's letter How to fix your entire life in 1 day, then keeps the result alive.

The day

Morning excavation

14 guided questions across three parts: face where you actually are, build your anti-vision, draft your vision.

Pattern interrupts

Six timed notifications through the day. One honest question each, answered in about thirty seconds — from the notification itself if you like.

Evening synthesis

Eight questions that distill the day into a one-page game you edit and lock in: the stakes, how you win, the year's mission, this month's boss fight, your daily quests, your rules.

Every day after

Your writing stays yours

There are no accounts and no servers of ours. Everything lives on your iPhone and syncs through your iCloud, in Apple's private database that we cannot read. No analytics, no ads, no tracking. See the privacy policy — it is short because there is little to say.

Price

Free for your first week — the whole protocol and the practice, nothing held back. After that, a single purchase unlocks it forever. No subscription. Reading and exporting what you've already written is never locked, whether you buy or not.

iPhone, iOS 17 or later. English and 简体中文.
