What you can do with it
Three things people open ClashClock for. Each links to the chapter of the user guide that covers it.
Every timer in one place
Home shows your next free builder as one big number, and a card for every running upgrade with its level, progress and finish time.
- Builders, the lab and the Pet House each get their own lane
- Reminders when an upgrade finishes, even with the app closed
- Home Village and Builder Base side by side
Plan around the hours you sleep and work
Add your offline hours once. The planner fills every builder’s lane so upgrades finish while you’re awake, and shows idle time in red where it can’t be avoided.
- Strategic rush, Max, or your own order
- Gold Pass boosts and potions are counted in every duration
- Drag, pin or remove any step; the plan adapts
See how far you are from maxed
Progress shows how much of a maxed village you already have, hall by hall, and how many builder, lab and pet days are left.
- Every Town Hall on one road, with what each one unlocks
- Hero Equipment counted per hero
- Cost per resource for everything that is left

Common questions
What is ClashClock?+
A free Clash of Clans upgrade tracker and planner. It keeps every builder, lab and pet timer in one place and schedules your next upgrades around the hours you're offline.
How do I plan my Clash of Clans upgrades?+
Import your village into ClashClock and pick a strategy: Strategic rush to the next Town Hall, Max, or your own order. The planner fills every builder, the lab and the Pet House around the hours you're offline, counts Gold Pass boosts and potions, and shows when your next Town Hall is ready. The Plan tab chapter walks through it.
What should I upgrade first at my Town Hall?+
Each Town Hall page lists what to upgrade first, the longest waits and how long maxing takes, worked out with ClashClock's planner from the game data. In the app, the plan does the same for your own village.
Is it really free?+
Yes. ClashClock is always free, and you don't need an account.
Do I need an account?+
No. Import your village and use it in your browser. An account is optional: it syncs your villages between devices and keeps heroes, lab, pets and equipment current from the game API.
How do I get my village in?+
In the game, open Settings → More Settings → Export Village Data and copy it, then paste it into ClashClock. It takes about a minute, and the user guide shows every step.
Where do the numbers come from?+
From Supercell's own game files, checked against two outside datasets. After a game update a new level or building can be missing until I add it by hand. How ClashClock works shows what is overridden.
Does it update automatically?+
Partly. The export is a snapshot, so import it again after you play or fix entries by hand. With an account, heroes, lab, pets, equipment and hall levels also refresh from the game API.
Is it made by Supercell?+
No. ClashClock is an independent fan project with no affiliation to Supercell.
