What you draw, Alice sees.
TwoIn is the app for two where you design each other's wallpaper. They see it every time they unlock.
You create on one side. They live it on the other.
One gesture, two screens. Nothing else to learn. The wallpapers shown here are examples.
Make their wallpaper in a minute
One to six photos in the layout you like, a finger doodle, emojis, stickers, a sweet note, even a song.
Alice gets it right away
A notification tells her it's there. On Android it can set itself; on iPhone the app guides her to set it in a few taps.
Or touch up their current one
Pick up your Duo's latest wallpaper and add your touch on top: a line, a word, a wink.
Her home screen changes
Every time she unlocks, it's you she finds. On Android, the TwoIn widget shows your latest wallpaper too.
Everything stays in your history
Every wallpaper you trade is kept in your Duo. See it full screen or set it again in one tap.
And now and then, a dated surprise
A time capsule stays sealed until the day you pick: a message, a photo or a voice note to open later.
Just the two of you.
TwoIn is not a social network. What you make stays between you.
What crosses to the other side
The wallpaper you make. Nothing else.
A fresh image made by the app, visible only to the person in your Duo. No feed, no likes, no ads.
What stays on your side
- Your contacts. Numbers are turned into unreadable fingerprints on your phone; none is sent in plain text.
- Your photos' location. It doesn't travel with the wallpaper.
- Your original photos. Only the finished wallpaper is sent.
And you stay in control: every sign-in is confirmed with a code, you can block or report in two taps, and deleting your account erases your data.
Both of you, install TwoIn.
Android and iPhone work together: each of you installs the app on your own phone.

Your questions.
On iPhone, does the wallpaper change by itself?
No: Apple doesn't let any app change the wallpaper. TwoIn saves it to your Photos and guides you to set it in a few taps. On Android it can be set automatically if you allow it in the app's settings.
Who can see the wallpapers I make?
Only the person in your Duo. There's no public profile, no feed, no sharing beyond the two of you.
Do we need the same phone?
No. An Android phone and an iPhone can make a Duo.
How do I invite my other half?
In the app, pick a contact already on TwoIn, enter their number, or share an invite link by text or messaging app.
How do I delete my account?
Go to Settings, then Account, and tap “Delete my account”. Your data is erased and your Duos end. See also our privacy policy.
