Track your menstrual cycle and fertility in complete privacy. PearPetal keeps your data on your own phone - no account, no server, no cloud. Not even we can see it. Your cycle blooms on a living petal dial: a flower that furls and opens as you move through your cycle, so a glance tells you your phase, your fertile window, and when your next period is due. KEY FEATURES - Private by design: your full cycle log lives only on your own devices, never on a server - The petal dial: a signature flower that tracks your phase across the cycle, plus a month calendar view - On-device predictions: next period, fertile window, and ovulation are computed on your phone from your own history - never sent anywhere - Log what matters: period start and flow, symptoms, mood, notes, and basal body temperature (BBT) - Goals that change the tone: general tracking, trying to conceive, avoiding, or a dedicated pregnancy mode - Cycle-aware for your body: enter conditions (like PCOS, endometriosis, thyroid) or birth control and predictions adjust - Share with a partner, on your terms: give a partner a scoped, read-only view - cycle phase only, your fertile window, or your full cycle - and end it any time - Gentle reminders: optional local notifications for your period or fertile days, with a discreet mode that hides the wording on your lock screen - Backups you control: export an encrypted, password-protected backup file to move to a new phone; nothing is ever uploaded - No accounts: your identity is a cryptographic key pair generated on your device - No data collection: PeerLoom, Apple, and no third party ever sees your cycle HOW IT WORKS PearPetal uses peer-to-peer technology powered by Hypercore Protocol. Your own devices - and a partner you have shared with - find each other and sync directly, device to device, with no middleman. All sync traffic is encrypted end to end, and every entry is cryptographically signed by the device that wrote it. The privacy boundary is structural, not a promise. Your full private log and anything you share with a partner live in two separate, separately-encrypted stores. The private log replicates only across your own devices. A partner share carries only the slice you consent to, written by you and read-only for your partner. Predictions are computed on your device and never cross the wire. Ending a share stops it going forward. PRIVACY - No accounts or sign-up required - No analytics, tracking, or telemetry - No third-party SDKs - All sync traffic is end-to-end encrypted - Your cycle data stays on your own devices, never uploaded anywhere - A partner only ever sees the scope you choose, and can never edit or re-share it IMPORTANT PearPetal is for personal tracking. Its predictions are estimates, not medical advice, not a diagnosis, and not a contraceptive method. Do not rely on them to prevent or achieve pregnancy. For medical questions, talk to a qualified healthcare professional. Open source. No vendor lock-in. Built by PeerLoom. ## Version history (last 3 releases) ### 1.0.4 — 2026-08-19 This one covers two releases. PearPetal can now bring your history in from another app, it keeps your cycle log out of anyone else's cloud, and it can reach your other devices even on networks that will not let two phones talk directly. New - Bring your history from another app. If you tracked somewhere else, you can now import your basal temperatures and period days from a file you export from that app. PearPetal reads Apple Health exports and the spreadsheet exports from apps like Samsung Health, Fitbit and Oura. The file is read on your phone and goes nowhere else, and anything you typed yourself is left alone. - Import straight from the Health app. You can pull your basal body temperature and period days directly out of Apple Health, with no file to export first. PearPetal asks only for permission to read. It has no permission to write anything back into Health. - A daily flower note. Switch it on and PearPetal sends one short line a day, written in the voice of the garden and matched to where you are in your cycle and to the flower you picked. It is off unless you turn it on, and Discreet mode softens it like every other reminder. - Connect anywhere. Some networks will not let two phones connect straight to each other, which could leave pairing or syncing hanging with no explanation. PearPetal can now pass the connection through a PeerLoom helper server, but only after a direct connection has already failed. Your cycle data stays scrambled the whole way and the helper cannot read any of it. It can only see that two devices are talking. This is on by default and you can switch it off under Settings, Connect anywhere. - Connection details. Under Connect anywhere you can see how your phone is really connecting: how many connections it made directly and whether the helper was ever needed. Privacy - Your cycle log is no longer part of your phone's automatic iCloud backup. It used to be eligible to be copied there. It no longer is, so your logged days, flow, symptoms, notes and temperatures stay on your own devices. Your settings still back up as before. - Settings now says so plainly. Under Backup & restore, PearPetal explains that the phone's own backup does not include your cycle log, and points you at the app's own password-protected backup, which is how to keep a copy you can restore from. Improved - A tidier Settings screen. Settings used to be several screens of scrolling with no clear order, and some things sat permanently open while more important ones were hidden. Everything is now grouped under Your cycle, How it looks, Alerts and connection, then Your data, and each group opens when you tap it. Your name and photo stay at the top. Fixed - Setting up no longer overfills your log. Telling PearPetal that your last period started a while back used to mark every single day since then as a bleeding day. It now fills in a normal period length instead. - The daily note and the dial no longer disagree. If you logged a flow for today, the note speaks from that rather than from the prediction. - On smaller phones, the Dial and Month switcher no longer covers the flower button and the information button at the top of the cycle card. Everything you track still stays on your own devices. ### 1.0.1 — 2026-07-16 The big one this release: PearPetal now works across more than one of your devices. Scan a QR code from your phone to link a tablet or a second phone, and your cycle log, your profile and your settings follow you there — still with no account, no server and no cloud. Everything syncs directly between your own devices, encrypted end to end. New - Link your devices with a QR code. Open Cycle settings Your devices to generate a code, scan it from the other device, and you're paired. New devices can link right from the welcome screen. You can see everything you've linked, and remove a device whenever you like. - A recovery phrase. PearPetal can now show you a twelve-word phrase that restores your identity and lets you re-link your devices if you lose one. It doesn't restore your cycle log on its own — that's what an encrypted backup is for, so keep making those. - Your settings travel with you. Name, avatar, cycle lengths, goal, flower, conditions and birth control now match on every device you've linked, and update as soon as they sync. Improved - A calmer Cycle view. The whole view fits on one screen now. Logging a day opens in a sheet that slides up over the dial instead of taking you somewhere else, the dial hints at today, and moving between months cross-slides rather than jumping. Fixed - The About screen shows the right version. It was stuck reading 0.1.0 no matter what you had installed. Existing logs carry over automatically the first time you open this version. Nothing you've tracked leaves your device. ### 1.0 — 2026-07-16 No release notes. ## More apps by Timothy Hudgins - [SatScream](https://appshunter.io/ios/app/satscream/id6759922209) - [PearCal: P2P Calendar](https://appshunter.io/ios/app/pearcal-p2p-calendar/id6760743056) - [PearGuard](https://appshunter.io/ios/app/pearguard/id6762235405) - [PearCircle](https://appshunter.io/ios/app/pearcircle/id6768703537) - [PearList](https://appshunter.io/ios/app/pearlist/id6787974942) All apps by Timothy Hudgins: https://appshunter.io/developer/1879898342 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
