Pick the box as you write
Pick a box on the left of the input bar and write. Inside a box the screen takes on the box colour, so you always know where you are writing.
Jot it down.
Drop it in a box.
A memo app that keeps your memos in boxes. Pick a box when you write, and open that box when you need it.
How it works
Lisbon Trip box
Links, photos and files in one place
Links get a title and preview, and photos and files go into boxes like memos. The Files tab in each box shows them together.
Today
To-dos and events on the Today screen
See today's to-dos and events on one screen. Set a time and you get a reminder then.
Work box
Longer writing and meetings go in notes
When a memo is too short, write a note inside the box. Notes support headings, lists and checkboxes.
Also
Bring memos from other apps
Export your messenger chat with yourself and share the file. The memos land in the Inbox with their original dates.
App lock
Lock the app with Face ID, fingerprint or your device passcode. Memos are saved to your account, so they stay when you change phones.

Common questions
Is it really free?
Yes. Writing, boxes, search, the quick memo widget and the Today screen are all free. On the free plan you can make up to 4 boxes; if you need more, choose Pro.
Does it move my memos into boxes on its own?
No. Memos stay in the box you wrote them in. When you move memos out of Inbox, the boxes you used before come first, so it takes one tap.
Can I bring over notes from other apps?
If you’ve been messaging notes to yourself, save that chat as an export file and share it to Diary Box. The memos land in Inbox with their original dates, and you can select several and move them into a box at once.
What happens to my memos if I change phones?
Memos are saved to your account, so sign in with the same account on the new device and they’re all there. You can also lock the app. For details, see the Privacy Policy.
Which devices does it work on?
iPhone, iPad, Android, Mac, Windows and the web. Write on one device and it shows up on the others right away.
