One Emoji a Day: Mood Tracking That Fits Inside Your Diary
A mood tracker does not need a scale from one to ten. One emoji and one sentence a day, kept for a month, show more than you would expect — if you know where to look.

10 Questions to Ask Before Choosing a Diary App
The right diary app should make it easy to capture a day, return to it later, and keep control of the record. Here are ten questions worth asking before you choose one.

What Writing Every Day Actually Does for You
No single diary entry is worth much. Three hundred of them, written on ordinary days, are worth a great deal — and that gap is the whole argument for making it daily.

Finding Any Memory: Calendar, Search, and Tags
A diary you cannot search is a box in the attic. Retrieval is the feature that makes the writing worth doing.

Reading Your Diary on a Second Device
Sync in ONEDiary is two switches, not one, and knowing which is which saves a lot of confusion when you get a new phone.

Most journals die in week three. Not because writing is hard, but because the entry you imagine writing is too big to start.

Photos, Places, and the Permissions We Chose Not to Ask For
Attaching a photo and a place to an entry should take one tap. Getting there meant declining two permission prompts we could easily have shown you.

ONEDiary saves entries on your phone first, so writing and reading work offline. Signed-in synchronization is optional; Offline mode pauses synchronization until you resume it.
