Features
What's actually in the app
Tracking that stays on your phone. That's the whole idea.
Know your cycle
Log your period, flow, and symptoms. After a few cycles, Bleed starts predicting your next one. No guesswork — just your own data doing the math.
We can’t see your health data
Your cycle data lives on your phone. We store your email for sign-in and that’s it. If someone subpoenaed us for your period data, we’d have nothing to hand over.
Cramps have patterns
Log what hurts and what changed. Over time you start seeing connections — like that headache that shows up two days before your period every single month.
Your hormones aren’t random
Track mood and energy alongside your cycle. Most people are surprised how predictable it all is once you actually see it mapped out.
Heads up, it’s coming
Get a notification before your period is due. Set reminders for birth control, doctor’s appointments, or whatever else you don’t want to forget.
None of their business
Lock the app behind Face ID or a passcode. If someone borrows your phone, they’re not getting into your cycle data.
Privacy
I built this so I couldn't see your data. Even if I tried.
We store your email for sign-in. That’s the only personal data on our server.
All health data stays on your device. Period data, symptoms, mood — none of it leaves your phone.
No analytics, no ad SDKs, no third-party trackers buried in the code.
We publish exactly what’s in the app. Check for yourself.
Your health data never touches a server. Your email is the only thing we store, and it's only used for sign-in.
How it works
Three taps and you're done
Sign in once, then the app works offline.
Download it
Free on the App Store and Google Play. Sign in with Apple, Google, or email. That’s the only thing we store on our end.
Log your period
Tap when it starts, tap when it stops. Add symptoms if you want. The whole thing takes a few seconds.
That’s it
Bleed figures out your cycle and starts predicting. Everything runs on your phone. There is no step four.
Reviews
Don't take my word for it
“I deleted Flo the week that privacy thing came out. Bleed only has my email and everything else stays on my phone. Why aren’t more apps like this.”
“Three months in and it predicted my period to the day. I don’t know how it does it with just the data on my phone but I’m not questioning it.”
“My last period app had a screen that said ‘your flower is blooming.’ Bleed just says ‘period started.’ Thank god.”
