WhenNote: Countdown & Days

Handstar Apps

About this app

WhenNote is a countdown and anniversary tracker with a built-in date calculator. Count the days until birthdays, anniversaries, exams and deadlines, see how much time has passed, and calculate the number of days between any two dates — all offline, with no account required.

Features:

- Countdown to any date and count the days since past events
- Organize dates into separate notebooks
- Record names, descriptions, start dates, and end dates
- See elapsed, upcoming, and remaining time at a glance
- Date calculator: total intervals and add or subtract days, hours, and minutes
- Optional reminders for important dates
- Reorder notebooks and entries to match your workflow
- Optionally back up and restore through your private Google Drive app-data area
- Choose an appearance style — Classic, Forest, or Dark
- Use the app in English, Traditional Chinese, or Japanese

Your notes are stored on your device by default. When Google Drive backup is enabled, WhenNote requests access only to its own hidden app-data area—not your other Drive files.

No ads. No tracking. No unnecessary account required.
