Make room for the habits that matter to you. RhythmKeep brings your daily routines, occasional responsibilities and one-time reminders into one clear view. TRACK PROGRESS YOUR WAY Check off a habit, count repetitions, record an amount, run a timer or work through a checklist. Keep partial progress, set flexible weekly targets or limits, and choose goals that fit your day. PLAN A REALISTIC ROUTINE Set repeating schedules and one-time reminders. See what is due in Today and plan ahead in Calendar. Search your personal habits from Today, including paused and archived entries. Give checklist steps their own reminder times when a routine happens throughout the day. Notifications require permission. SHARE WITH FRIENDS AND FAMILY Send someone a copy to track independently, or invite them to track a shared habit. Choose individual check-ins or let one completion count for the group. Share check-ins, amounts, minutes and checklist progress. An iCloud account and internet are needed to invite people and transfer updates; offline changes wait on your device until iCloud confirms them. Personal notes and past private history stay private. START WITH AN IDEA Explore 130 presets across 13 categories, including focus, reading, journaling, household routines and more. Filter ideas by category or tracking style. Save a preset idea for later without creating a habit, then review and customize its schedule and goal when you are ready. SEE YOUR EFFORT OVER TIME Review your recent progress and completion history. Correct an accidental log or record progress you missed. RhythmKeep Pro adds detailed Rhythm reports, period comparisons and longer-term insights to help you notice patterns in your recorded activity. FREE AND PRO The free plan includes up to five current habits, the last seven days of Rhythm progress and data export. RhythmKeep Pro adds unlimited current habits, detailed Rhythm reviews and backup import. Paused habits count toward the free allowance; archived habits do not. Prices and available subscription plans are shown in the app before purchase. Subscriptions renew automatically unless canceled in your account settings. RhythmKeep helps you organize and reflect; it does not promise a specific habit-formation outcome.
