Mosaic DIY Tile support
Email us and we'll help. Tell us which device you're on and what you were doing; a screenshot helps.
Restore your unlock on a new device
Open Mosaic, tap the gear on Home, then Restore Purchases. On a Mac, choose Mosaic › Settings…. Use the same Apple Account you bought the unlock with. One unlock covers your iPhone, iPad and Mac.
See your designs on all your devices
With the unlock, Mosaic saves your designs and keeps them in your own private iCloud storage. Sign in to iCloud with the same Apple Account on each device, and your designs follow you.
Send a design to someone
In a design, choose ⋯ › Export… › Send. It shares a Mosaic file, with a PDF for anyone who doesn't have the app. Someone with Mosaic but without the unlock can still open it with Try it.
About the counts and the installation map
They're a planning aid. Dry fit your tiles before you install, and check the counts with your installer or tile store before you order.
Delete your data
Delete a design in Mosaic to remove it and its version history, from all your devices when iCloud is on. Deleting the app removes what's on that device. Mosaic's iCloud data can be removed in your device's iCloud settings.
What you need
An iPhone or iPad with iOS 26 or iPadOS 26 or later, or a Mac with macOS 26 or later.
