ourRegla is a calm period tracker where your health data lives only on your phone. Invite your partner with a code and they get a gentle heads-up instead of guessing — plus stickers and cheeky invitation cards for when "I'm on fire, come put it out" is easier to send as a cartoon than to say out loud. Everything shared is end-to-end encrypted. No ads, no trackers, 21 languages, Android, iPhone and Apple Watch.
