Invite-only beta · Android · 18+
Track your cycle.
Tune your mind.
CycleAffirm is a period tracker and an affirmation app in one. It knows which phase you're in, asks how you're actually feeling, and gives you one line a day that fits both. Like a bestie who gets it.
Luteal · today's line
Extra sensitive is just feelings in 4K. Nothing's wrong with you.

- Curiosity is your cheat code this week.
- Comparison is a thief. Don't give it your password.

- Cozy, quiet, and slow is a perfectly elite plan.
How it works
Four phases, four moods. One line a day that gets it.
-
Log your period
Tap “Period started?” when it does. CycleAffirm works out your phase and day and shows them on a ring.
-
See what's coming
“Period in about 6 days.” Every prediction is labelled an estimate, and it learns your real cycle length as you log.
-
Get a line for the phase
Each morning there's an affirmation written for where you are, in the voice of a friend who's funny about it and kind about it.
-
Menstrual around days 1–5
Often feels like: a time to rest and turn inward.
Low battery mode is a feature, not a bug.
-
Follicular around days 6–12
Often feels like: energy is building, fresh starts feel easier.
New era unlocked. Start the thing.
-
Ovulatory around days 13–16
Often feels like: peak energy and confidence.
Take the compliment. Do not argue with it.
-
Luteal around days 17–28
Often feels like: slowing down, feelings run deeper.
Protect your peace like it's your phone at 2%.
Days shown for a 28-day cycle. CycleAffirm fits the phases to your own cycle, and every prediction is an estimate. Not birth control or medical advice.
Try a check-in
How are you, really?
In the app, a check-in takes seconds. Tell it how you actually feel and today's line changes to match you, not just the day of your cycle. Try the mood part here.
- A few sliders, a few words. Energy, mood, sleep, calm, body and self-worth, the moods that fit, and a note if you want one.
- A line that fits. You get a balance score and the best line for your phase and mood. Add a note, or have a really low day, and the AI writes you a fresh one, if you've said yes to AI.
- It learns what helps. Check in a few times and, when a phase ends, it remembers what worked, so that phase's lines fit better next cycle.
Optional · for your person
Let your person in on it. You pick what they see.
Invite your partner and they get a heads-up on your phase, gentle ideas for showing up, and a nudge to tell you something nice. Nothing is shared until you make the invite.
-
01
You make the invite
Create an 8-character code and pick what they see: your phase and when your period's due, plus, only if you switch them on, how each phase usually feels and your daily moods. Never your notes.
-
Supporting her
Luteal · Slowing down. Feelings run deeper.
She's feeling insecure today. Reply a bit faster than usual and keep it warm.
02
They get gentle tips
Plain, practical ideas for the phase you're in, as often as they like: every morning, in the evening, only on turning-point days, weekly, or not at all. Lock-screen wording never mentions your cycle.
-
7:30 pm
CycleAffirm
A note for her?
Write her a few words that make her feel good about herself. One line is plenty.
03
A 7:30 pm nudge to write you a note
With ideas to start from if they're stuck. They can move the time or switch it off.
-
04
It lands on your home screen
Their note shows on your Today screen, and on your home-screen widget if you've added it. Hide it, report it, or remove and block them anytime.
Family and friends can join too. They see your phase, never when your period's due. Remove anyone and they lose access straight away.
Pinky promises
Your cycle is not our business model.
Period data is personal. Here's the short version. The privacy policy has every detail.
-
Stored with Firebase
Your data lives in Google's Firebase, behind rules that let only you read it. People you invite see only what you chose to share.
-
AI only after “I agree”
Affirmations are written with help from Anthropic's AI. Nothing goes to it until you tap “I agree”, your email and account ID never do, and you can switch it off in Settings.
-
Never sold. No ads.
No ads, no ad SDKs, and no tracking you across other apps. This website has no trackers either.
-
Delete it all, anytime
One tap in the app deletes your account and data. No app any more? Ask us on the web.
