A diary that takes thirty seconds
One line.
Every day.
Write a single sentence about today. Next year, on this very morning, it is the first thing you see. And the year after that, both of them.

How it works
Thirty seconds tonight. The whole day back, a year from now.
Write one line
One box, 280 characters, saves as you type. It is too small to skip, which is the whole point.
Burnt the toast, caught the train anyway
Tag the day, if you like
A mood from rough to great, the weather, a photo. All optional, all one tap.
Next year, it finds you
You never scroll back through old pages. The line you wrote a year ago is already on the page when you open it, with the year before underneath.
Year in review
A year of days, one small square each.
Tag your days and the year becomes a strip of colour. The review picks out your longest run, the words that kept coming back, and the hottest day you wrote about.
There is a share card too. It carries the numbers and none of your lines.

Built to be kept
Private by default. Portable for good.
A lock only you open
Set a PIN and the diary locks itself when you step away. Nothing is shown until you enter it.
On your home screen
Add it to your phone and it opens full screen, straight to today. No app store.
A nudge at your hour
An optional morning email with this day last year, sent only on days you have not written yet.
The sky, remembered
Set your town once and each line keeps that day's weather beside it.
A photo, when words fall short
Attach up to four photos or videos to a day. They are stored privately and only you can open them.
Yours to take away
Download every line as CSV or JSON whenever you like. Delete your account and all of it goes with you.
Today is as good a first line as any.
Whatever you write tonight will be waiting here on 9 November next year.
