Never leave a builder idle again.

BuilderBell pings you the minute a builder, the lab or the pet house frees up, for every Clash of Clans village you play. It also shows how far each village is from max, and when you'll get there.

What you get

Everything your builders are up to, in one place

Made for players with more than one village, who want the next upgrade started the moment a builder is free.

Alerts on the minute

Builders, lab, pet house and helpers. Every alert names the village, and if a builder is still idle an hour later, you get one more nudge.

All your villages

Every account on one screen, with its in-game name and clan. See who has free builders and what finishes next, across all of them.

How far from max

Percent maxed for your Town Hall, the date you'll be maxed, and what's holding you back: builders, lab or pets.

Every upgrade priced

Cost and time for every level, with your Gold Pass boosts and the current event discounts already applied.

Home-screen widget

Free builders, idle labs and the next three finishes, without opening the app. Tap a row to jump to that village.

Builder Base too

Builder Base timers, Star Lab and progress sit right next to your home village.

How it works

Copy, open, get a ping

Clash of Clans can copy your village's levels and timers as text. BuilderBell reads that copy. That's all it needs.

Copy your village

In the game, open Settings and copy your Data Export.

Settings → More Settings → Data Export → Copy

Open BuilderBell

It finds the copy on your clipboard and adds or updates that village, with a summary of what changed and an Undo.

Get a ping

When something finishes, you get an alert naming the village. Start the next upgrade, copy again, done.

Inside the app

Fair play, by design

  • Never asks for your Supercell ID, email or password.
  • Doesn't touch the game: no automation, no overlays, no mods. It only reads the text you copy with the game's own Data Export.
  • Your villages stay on your phone. Only your player tag goes to our server, to fetch your public name and clan.
  • Free. A small banner ad pays the bills: no pop-up ads, and nothing locked behind a payment.

Coming soon to Google Play

BuilderBell is in testing now and launches on Google Play for Android soon. It will be free.
