Why Circle
Built for the ring. Not the pill.
Generic reminder apps think in days. The ring works in weeks — 21 in, 7 out, or your own schedule, including continuous use. Every reminder, countdown, and insight in Circle is built around that rhythm.
One cycle, exactly as the ring works
Day 12 · Ring week · 9 days to removal
Features
Everything the ring needs. Nothing it doesn't.
Circle does one job exceptionally well: keeping you on schedule and informed, without turning your birth control into a project.
Reminders that break through
Precise notifications for insertion, removal, and the end of your break week — with optional critical alerts that get past silent mode and Focus.
A live countdown, always
Open the app and see exactly how many days until your next ring event. No calendar math, no counting on your fingers.
Know you're protected
Clear protection status at a glance — including honest guidance if your ring was out longer than it should have been.
Your whole cycle, mapped
Ring weeks, break weeks, and every logged event on one calendar. Look back at any cycle, any time.
Check in, in seconds
Log bleeding, symptoms, and mood with a couple of taps — then watch your patterns emerge across cycles.
Private by design
No account, no sign-up, no ads. Your cycle data stays on your device — it's nobody's business but yours.
A look inside
Calm on the surface. Precise underneath.
A clean, quiet interface that tells you exactly what you need to know — and nothing you don't.
Today at a glance
A live countdown and your protection status, front and center.
Your whole cycle
Ring weeks, break weeks, and every event on one calendar.
Yours to shape
Your schedule, your reminder times — and no account, ever.
Peace of mind
The quiet confidence of never wondering.
Circle isn't an app you spend time in. It's an app that gives you time back — and the certainty that nothing slips.
One less thing to carry
The ring's schedule lives in Circle, not in the back of your mind. Set it once and let it go.
Reminders you can trust
Notifications survive time-zone changes, daylight-saving shifts, and silent mode. When Circle says it will remind you, it does.
No 3 a.m. doubt
“Am I still protected?” has a clear answer, day or night — right on the Today screen.
Effortless to keep up
Confirming an event takes one tap. Checking in takes a few seconds. There's nothing to maintain.
How it works
Four steps. Then it just runs.
Circle asks very little of you — that's the point.
