About
"How many days has it been?"
Day Memo quietly counts the days since the moments that matter to you.
The day your child was born. Your wedding day. The day you quit smoking. The day you bought your car.
Add the date once, and let the count grow.
■ Three ways to count
- Days elapsed: how long has it been?
- Years elapsed: which anniversary is this?
- Countdown: how many days until the next one?
Switch to countdown mode for things that live in the future, like an inspection or a renewal.
■ Milestones, handled for you
100 days. 6 months. 1, 2, 3, 5 and 10 years. And 1000 days.
Day Memo notifies you as each one approaches, so nothing slips by.
You can also set your own reminder on any event.
■ Home Screen and Lock Screen widgets
See today's count without opening the app.
Two sizes on the Home Screen, three on the Lock Screen.
The medium widget lists up to three events, each with its photo.
Which of your favourites appears changes from day to day, so an anniversary you had not thought about in a while can catch your eye again.
■ Share cards with your photo
Turn any count into a single image worth sharing.
Choose from 12 backgrounds, from soft pastel balloons and starry skies to Japanese designs featuring cherry blossoms and shrine gates.
A caption with hashtags is generated for you with one tap.
■ A little about the date itself
Open an event and you will also see:
- Japanese era year
- Star sign
- Birthstone
- Chinese zodiac
■ Built to stay out of your way
- Categories (Family, Car, Health, Anniversary, Other - add your own)
- Search by name, date or memo
- Pin favourites to the top
- Four colour themes
- Three text sizes
- English and Japanese
■ Your data stays on your device
No account. No sign-up.
Nothing you enter is ever sent to a server. Events and photos live only on your device.
Export a backup file whenever you like, and keep it wherever you choose.
Three digits become four before you notice.
Day Memo is a quiet place to keep that count.
