TBH Reminder

Personal Reminder is a simple, fast timer and reminder app that works completely offline. No account, no ads, no tracking — your data never leaves your device.

THREE WAYS TO SET A TIMER
• Countdown — count down from any time span, from seconds to years
• Count until — count down to a specific date and time
• From → to — a fixed time window; the start can even be in the past, and the alarm rings at the end

QUICK TO CREATE
• One-tap timer creation from the Quick Settings tile or by long-pressing the app icon
• Numpad quick input: type 202 and get 2 minutes 02 seconds — digits fill from the right, just like a kitchen timer
• Optional auto-start when a timer is created or updated

ALARMS THAT GET YOUR ATTENTION
• Full-screen alarm with sound and vibration, even when the screen is locked
• Gradually increasing volume — start soft and grow louder (configurable)
• Snooze with your own duration, repeat on a custom interval
• Use the built-in tone or pick any sound file on your device
• Test the alarm while you configure it

STAY IN CONTROL
• Run many timers at once — every timer is a reminder
• Pause a countdown and resume later from the same point
• Keep finished timers to reuse, or let them delete themselves when done
• Dark mode: follow the system or choose light/dark

YOUR DATA IS YOURS
• Everything is stored locally on your device
• Export and import all timers as a CSV file
• No permissions beyond what alarms need

Personal Reminder is built for people who want a reliable, no-nonsense timer app: set it, forget it, and let it ring.
