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.

Calendar wallpaper vs lock screen apps

Short answer: a lock screen app draws its own screen on top of the system lock screen, while a calendar wallpaper only changes the lock screen's background image. That's why the wallpaper approach structurally has no double unlock, no lock screen ads and no loading delay — at the cost of not being able to tap and edit events right on the lock screen.

1. How they differ

An overlay lock screen app launches every time the screen turns on and covers the existing lock screen. A calendar wallpaper app just sets one image through Android's standard wallpaper feature; nothing runs when you wake the phone.

2. Side by side

Unlocking: overlay apps often mean swiping past their screen and then unlocking again — reviews say "Requires double unlock". A wallpaper leaves your normal unlock, fingerprint and face unlock untouched.

Ads: overlay apps can show ads on the lock screen itself ("Ads on your lock screen? Not a good look."). A wallpaper is only an image, so no ad can appear on the lock screen.

Speed: overlay apps must draw on every wake, which can cause delays like "I have to wait 10 seconds every time I unlock my phone". A wallpaper is pre-rendered, so there is no delay.

Interaction: overlay apps let you add or check off to-dos from the lock screen. A wallpaper is view-only; you add events in your calendar or inside the app.

3. Which one fits you

If checking off tasks on the lock screen matters most, an overlay app fits. If you just want to "look at my phone and see it to remember" without anything interfering with unlocking, security or ads, a wallpaper fits better.

4. Daypaper is a real wallpaper

Daypaper only sets a real wallpaper. It redraws itself at midnight and whenever your calendar changes, applies to the lock screen, home screen or both, and reads your calendar on-device with no sign-up.
