Does the wallpaper update automatically when my calendar changes?

Yes. Daypaper detects calendar changes and redraws the wallpaper within a minute, and switches to the new day at midnight. It works without a home screen widget, and you never need to open the app to refresh.

How do I see my to-dos from my Google Calendar on the lock screen?

Install Daypaper, allow calendar access, and apply the wallpaper to the lock screen. Any Google account synced to your phone's calendar shows up — you choose which calendars to include.

Will it put ads on my lock screen or require a double unlock?

No. Daypaper sets a normal wallpaper image instead of drawing over your lock screen, so there are no lock screen ads, no double unlock and no loading delay when you wake your phone. Fingerprint and face unlock work as usual.

Can I keep my home screen photo and change only the lock screen?

Yes — lock screen only is the default. You can switch to home only or both in settings.

Can I show only one Gmail account's calendar?

Yes. Pick exactly which synced calendars appear, and hide the rest.

Can I change the monthly view to a weekly view?

Yes. Choose between a full month, the next 7 days, or a today list with times.

My lock screen clock covers the calendar. What can I do?

Turn on the "lower content" option to move the calendar and events toward the bottom of the screen, away from a large clock.

Do I need an account? Is my calendar uploaded?

No sign-up. Your calendar is read on your phone only to draw the wallpaper and is never uploaded.

Lock screen calendar not updating? Causes and fixes

Short answer: most lock screen calendars stop updating because the app only redraws when you open it or when a home screen widget is installed. Use an app that detects midnight and calendar changes on its own, and exclude it from battery optimization.

1. What users run into

Reviews of calendar wallpaper apps keep saying the same thing: "not auto-updating home screen wallpaper calendar on next day", or that events added to the calendar don't show until the app is opened again. The wallpaper still shows yesterday, or a new meeting is missing.

2. Cause 1: refresh tied to a widget

Some calendar wallpaper apps only redraw periodically if you add their home screen widget and turn on auto-update. No widget, no refresh. That doesn't suit anyone who wants the calendar on the lock screen and a clean home screen.

3. Cause 2: battery optimization

Android delays or blocks background work for apps you rarely open. On Samsung phones, an app placed in "Sleeping apps" may never run its scheduled refresh.

Settings → Apps → the calendar app → Battery → set to "Unrestricted"
Samsung: Settings → Battery → Background usage limits → remove it from sleeping apps
Open the app once and re-apply the wallpaper

4. How Daypaper stays current

Daypaper refreshes without a widget through three paths: a midnight alarm switches the date, a calendar change listener redraws within a minute of any added or edited event, and a periodic check catches anything missed. You never need to open the app; the optional home widget adds a one-tap refresh if you want it immediately.
