About this app

Calmdo is a to-do list that stays on your phone and reminds you on time.

No account. No ads. No tracking. No cloud. The app has no server to send your tasks to — everything lives on your device, and one tap exports all of it to a single file you own. Built for busy, distracted, real-life brains.

TYPE IT THE WAY YOU'D SAY IT
"call mum in 2 hours every week" becomes a task with a date, a time and a weekly repeat. Dates, times, repeats, #tags, @lists and !priority are read as you type. Before you save, editable chips show exactly what the app understood — fix anything with one tap.

REMINDERS BUILT TO SURVIVE YOUR PHONE
Most to-do apps go quiet because Android shuts them down in the background. Calmdo uses exact alarms, re-schedules every reminder after a reboot, and runs a periodic check that catches reminders your phone silently dropped. If your phone doesn't allow an exact alarm, the task is marked "Approximate" instead of pretending it will fire on time. The Today screen always shows your next alarm and whether it's armed.

SEE THE PROOF, NOT A PROMISE
The Reminder Health Check screen logs what actually happened to every real reminder — scheduled, fired, snoozed, or rescheduled — so you can see it, not just trust it. Test an alarm right from onboarding, before you commit to anything.

ONE TASK AT A TIME
• Today view — only what matters now
• Focus mode: one task, fullscreen, with a countdown ring
• Break a big task into small steps with starter templates (taxes, packing, cleaning, "start a scary task")
• Auto-rollover: unfinished everyday tasks move quietly to Today — no red pile of overdue guilt
• Snooze right from the notification: Done or Snooze 10 min, always free
• Gentle streaks, and a done-check that feels good

THE REST OF THE LIST
• Due dates and times, reminders before the task
• Repeats that behave: daily, weekly, monthly, last day of the month, and "X days after completion"
• Subtasks, tags, lists, priorities, time estimates
• Dark and light theme

YOUR DATA STAYS YOURS
The app cannot leak what it never collects. A full backup exports everything to one file. Import it anywhere, anytime. No lock-in, ever.

WHERE THE FREE VERSION ENDS
The free version is a real app, not a demo: reminders, natural language, repeats, focus mode and backup, with up to 15 active tasks and 3 lists. Past that, a single lifetime unlock removes the limits, adds a choice of snooze lengths and your full reminder history, and includes every future update. Reminders, repeats and backups are never behind it.

Made by a tiny independent studio. No investors to please — only you.
