Pick the modes you need:

📅 Parental Custody
Build a clear custody / parenting-time schedule between two parents. Set weekly or bi-weekly rotations, add schedule changes and one-off exceptions (holidays, swaps), and see at a glance who has the children on any day. Rondo records and visualises an arrangement you have already agreed. It is not legal advice or a court order.

🔄 Co-ownership
Share anything that rotates between people: a pet, a car, a holiday home. Add one to ten owners, set the rotation, and everyone can see whose turn it is.

🩸 Period Tracker
Track your cycle, symptoms, mood and notes, with cycle and fertile-window predictions and an optional pregnancy mode. Your period data never leaves your phone and can never be shared. Rondo is not a medical device and must not be used for contraception, fertility planning, or diagnosis. Always consult a qualified healthcare professional.

🏃 Stay Active
Turn your daily steps, distance and active energy into a simple activity score, follow your progress on a colour-coded calendar, and, if you choose, climb a global leaderboard. Your raw health data stays on your device.

Private by design
• Everything works offline. Your data lives on your phone unless you choose otherwise.
• No account needed to use Rondo or to share a schedule.
• A phone number sign-in is optional. It adds two things: a backup of your Parental Custody and Co-ownership schedules that you can restore on a new phone, and the leaderboard, which shares your score, nickname and country publicly. Period Tracker and your raw health data never leave your phone.
• What does sync is encrypted on your phone first. We store schedules, names and logs we cannot read.

Sharing
Share a Parental Custody or Co-ownership schedule with another Rondo user, view-only. You read out an eight-character code, they type it in, done. No phone numbers, no links, no group chats.

Free and premium
The full scheduler and all trackers are free. Premium (by watching a rewarded ad for one week, or a yearly subscription where available) unlocks sharing and joining the leaderboard.
