A pregnancy tracker that keeps everything on your phone. No account, no cloud, and it works offline. Your data is encrypted on your device, and only you hold the key.
It's called Birth Control because that's the point: your pregnancy, under your control.
Not your carrier's. Not an ad network's. Not a subpoena away on somebody's server. Pregnancy data is some of the most sensitive data there is, and the only copy of yours lives encrypted on your phone.
Week-by-week progress and the tools you actually reach for,
running on your phone, not in someone else's data center.
Your week, trimester, and a size-comparison milestone for every week of the journey.
A progress ring from positive test to due date, with days remaining at a glance.
Tap to count movements. Sessions are timed and saved so you can spot changes.
One button times each contraction and the interval between, with a simple pattern readout.
Keep visits and a running list of questions for your provider, with optional discreet reminders.
Log how you feel and track weight over time on a simple chart. All of it stays local.

No subscription. No upsells. No ads.
In an encrypted database on your phone, and nowhere else. There is no account and no server. The app works fully in airplane mode.
The app locks behind your PIN or Face ID and auto-locks on its own. If you are ever forced to open it, a decoy PIN opens a separate, empty vault.
No, and that's the point. Your PIN unlocks the encryption key, which never leaves your device. Keep an encrypted backup with a passphrase you remember.
No. Due dates, week counts, and milestones are informational estimates, not medical advice. Always rely on your healthcare provider.
