The problem
Knowledge workers average 2.9 deep work sessions a week. Meetings eat 4.2 hours a day. 61% of your calendar is reactive — Slack, email, syncs with no agenda.
Most days have only 30–60 minutes of real focus — buried in noise.
The solution
Apple Watch, Pixel Watch and Galaxy Watch tell us when you have energy. Your calendar tells us when you're free. We tell you when to do the hard thing.
25/5 was invented in 1980. Flow's sessions adapt to your biometrics in real-time — extending when you're locked in, pausing when your body says rest.
Most apps want you to add. Flow tells you what to delete — which meeting to cancel, which task to drop, what's not worth your peak hours.
How it works
Two taps. Done. Grant Flow access to HealthKit (or Health Connect) and your calendar. Nothing leaves your device unless you ask for a plan.
Wake up. Flow has 2–3 deep work blocks already scheduled, based on your sleep, HRV, and calendar.
Tap Start. Focus mode kicks in. The timer adapts to your biology — extends when you're in flow, breaks when HRV drops.
Free email course
A free email course. One email a day. Real exercises, no fluff. No pixels tracking you.

Questions
No. Pomodoro is a fixed 25/5 timer invented in 1980 with a kitchen timer. Flow reads your HRV and sleep, then adapts each session's length to your real-time biology. When you're locked in at minute 47, Flow extends. When your heart-rate variability drops, Flow nudges you to rest before you burn out.
Motion and Reclaim are calendar-scheduling tools — they tell you when to do tasks. Flow tells you when to focus based on your energy. They schedule. We coach.
Flow works without a watch — we use your calendar, manual check-ins, and pattern history. With a watch (Apple, Pixel, Galaxy, Fitbit), the plan gets sharper week-over-week.
Yes. HRV and sleep data live on your device through Apple HealthKit and Android Health Connect. Aggregated, anonymized signals (peak window, recovery score) are sent to our server only when you trigger a plan. We don't sell data, we don't run third-party ad trackers, and you can delete your account — and every byte of data with it — from inside the app.
Q3 2026. The waitlist gets 7-day early access before public launch, and 30% off lifetime locked for early subscribers. We build in public — you'll see the milestones in your inbox along the way.
Both. Flow is built cross-platform from day one. Google Play ships first, Apple App Store follows within a few weeks. Apple Watch, Pixel Watch, and Galaxy Watch 6+ are all supported for HRV signal — if you don't wear a watch, Flow falls back to a calendar-only plan with slightly less precision.
2–3 deep work blocks every morning. Built for indie knowledge workers like you.
