Free to organize your co-parenting. One subscription to connect.
Encrypted end to end. Only the two of you can read it.
Co-oper8 is the private way for separated parents to run a shared custody schedule. Set your parenting split once, and both calendars stay in step — each parent sees the schedule from their own perspective.
ORGANIZE - FREE, FOREVER
• Your custody calendar with your parenting split (7-7, 9-5, whatever works)
• Change your start date up to 3 times free; adjust the split anytime
• Pick individual days by hand (5 included)
• Your schedule history - look back at past arrangements, shown faded on the calendar as a "ghost" of what was
CONNECT - ONE SUBSCRIPTION PER FAMILY
• Propose your schedule to your co-parent; it applies only when they accept
• Agreed pick-up and drop-off times - partial days show as half-circles, so a school-pickup Wednesday looks different from an all-day Wednesday
• Your co-parent pairs, messages, accepts and exports for free
PRIVATE BY DESIGN
• Messages and schedules are end-to-end encrypted on your devices - no one else can read them. Not even us.
• Verified pairing: Settings shows "Paired" once both devices provably share the same secure key
• Messages can't be edited or deleted once sent - the conversation stays a reliable record for both of you
• Export matching PDF transcripts and schedule-history reports anytime, free
AND WHEN YOU NEED A HUMAN
• Book time with a mediator directly from the app - some things need a conversation, not an algorithm
Co-oper8 subscriptions are auto-renewable (monthly, quarterly, half-yearly or yearly). Payment is charged to your Apple Account at confirmation of purchase; the subscription renews unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in Apple Account settings. Terms & privacy: https://www.connected-health-insights.com

• Handover times — agreed pick-up and drop-off times, with partial days shown as half-circles on the calendar
• Schedule history — scroll back in time and see past arrangements as a faded "ghost"; export the full change history as a PDF
• New Help & Tutorials section, a fresh app icon and look
• Fairer free tier — pairing and messaging are free, plus 3 free start date changes
