Setting up Let's Tile
Five minutes, once. No account, no sign-in.
Download the app
One file,
Download Let's TileLetsTile.dmg, lands in your Downloads folder.Drag it to Applications
Double-click it. A window titled LetsTile opens with the app on one side and your Applications folder on the other — drag one onto the other.
Don’t skip this and run it from that window: an app launched from a disk image can’t keep its permission, so it asks again every time. Once copied, eject LetsTile from the Finder sidebar with ⏏.
Open it for the first time
Double-click LetsTile in Applications. macOS asks whether you’re sure about an app from the internet — click Open. You’ll only see it once; the app is signed and notarised by Apple.
Allow Accessibility
A welcome window explains why, then System Settings opens on Privacy & Security. Switch LetsTile on. Your Mac may ask for your password — that’s macOS guarding the setting, not the app.
AccessibilityRequired
Reads and moves your focused window. Without it the grid appears but nothing snaps.
Open this setting on your Mac →Look in the menu bar
No Dock icon, no main window — this trips up everyone. Let's Tile lives in the menu bar, top-right near the clock. Click it for Settings…, About and Quit.
Try it
Open any app, then press:
⌘↵A grid drops over the window you were just using. Steer the highlight to the cell you want, then press ↵ — the window snaps into it.

Bought Pro? Paste your key
Your key arrived by email right after checkout. Menu bar icon → Settings… → General → paste it into the license field and activate. Pro unlocks straight away.
No account, nothing to log into — the key is stored in your Mac’s Keychain. Copy it from the email rather than typing it, with no spaces either side. One key covers up to 20 devices, so reuse it on your other Macs.
If something isn’t working
- The shortcut does nothing.
- Almost always the Accessibility switch. Check that LetsTile is listed and on under System Settings → Privacy & Security → Accessibility — and if it already is, toggle it off and on.
- It’s on and still nothing happens.
- You probably granted a copy that’s gone — the one in the disk image or in Downloads. Quit the app, remove LetsTile from the list with −, then open it from Applications and grant it again.
- macOS says “LetsTile” is damaged.
- The download didn’t finish. Delete
LetsTile.dmgand download it again from this page. - My license key isn’t accepted.
- Check for stray spaces and that you copied all of it. The first activation needs internet; after that it works offline. Still refused? Forward us the purchase email.
- I want it to start when my Mac does.
- Menu bar icon → Settings… → General → turn on the launch-at-login toggle.
Still stuck? Just ask.
