A FEW THINGS TO KNOW

A few things to know

Do I need exactly four photos?

No. Both diary entries and the photo booth work with one to four photos.

What can I use for free?

Diary entries, the calendar, themes, widgets, basic photo editing, app lock, and manual file backup and restore are free. The free version shows a journal banner and limited full-screen ads after an entry is saved. An active Plus subscription removes both ad formats and includes saving and sharing photo booth images and monthly PDFs. Check the purchase screen in the released app for pricing and availability.

Can I move my diary to a new phone?

Yes. Create a file backup and restore it on your new device. Before uninstalling the app, keep the backup in a safe place outside the app.

Does deleting my account cancel my subscription?

Account deletion and Google Play subscription cancellation are separate. See the account and data deletion guidefor deletion details and subscription management.

Which devices are supported?

Day in Four is an Android app. Download it on Google Play and check device compatibility there.
