A focus app for iPhone and Android

One thing a day.
Done well.

Too many priorities? Dayflint asks one question each evening: if you only got one thing done tomorrow, what would it be? Then it helps you actually do it.

How it works

A day with Dayflint

  1. 9:00 PM · The night before

    Pick tomorrow's one thing.

    One question, once a day. Choosing the night before means you wake up already knowing, with no list to wade through and no guilt about the rest.

    Dayflint's weekly plan, with one task for each day

  2. 9:00 AM · Morning

    Wake up knowing.

    A gentle nudge reminds you what today is for. The one thing sits front and centre, and anything extra waits quietly below it.

  3. 10:15 AM · Focus

    Hold to start. Phone face down.

    Press and hold to begin a 25, 50 or 90 minute session. Add soft brown noise or rain if it helps you settle in. Dayflint keeps time, and Flinty keeps you company.

  4. 11:05 AM · Done

    That's today's one thing.

    A quiet chime, a happy flame, and a dot on your week. Note how it felt, line up tomorrow, and get on with your day.

Streaks

Streaks that rest,
not reset.

Life happens. Miss a day and your streak rests instead of starting over. One rest day a week is on us, so a single slip never wipes out your progress.

Dayflint after a missed day: Yesterday slipped. It happens. Your streak is resting, not reset.

Everything it does

Small on purpose.
Thoughtful everywhere.

FAQ

Good questions.

Something else? Get in touch.

Why only one thing?

Because a long list makes everything feel equally urgent, and nothing gets finished. One clear priority is easier to start, easier to protect, and far more satisfying to finish. If you have time left over, Plus lets you add a few extras below it.

What happens if I miss a day?

Your streak rests instead of resetting. One rest day a week is built in, and the thing you missed carries over so you can relight it or pick something new.

Do I need an account?

No. There's nothing to sign up for. Open the app and pick your one thing.

Does Dayflint work offline?

Yes. Everything is stored on your phone, so it works anywhere. On iPhone, changes sync through iCloud when you're back online.

Is there a trial or intro offer?

On iPhone, monthly Plus is $1.99 for your first month, then $5.99 a month. Annual is $29.99 a year with no trial. On Android, annual and monthly start with 7 days free. Either way, the app reminds you 2 days before the full price starts, and you can cancel in your Apple ID settings or Google Play before then. Lifetime is $49.99 once and does not renew.

Is it on Android or iPad?

Dayflint is on iPhone (iOS 17 or later) and Android (8.0 or later). There's no dedicated iPad version. Your days don't sync between iPhone and Android.

Tomorrow's one thing
