POWER ACTIONS

What can it trigger?

Any timer or battery rule can fire any of these actions:

⏻ Shutdown
↺ Restart
❄ Hibernate
☽ Sleep
🔒 Lock Screen
⇥ Log Off
HOW IT WORKS

Simple as setting an alarm.

Three steps and your PC takes care of itself.

1
Create a timer
Type a duration in any format — 1h30m, 90:00, or just 5400 seconds. Give it a label so you remember what it's for.
2
Choose an action
Pick what happens when the timer fires: Shutdown, Restart, Hibernate, Sleep, Lock, or Log Off. Optionally set it to repeat.
3
Minimize and forget
Minimize to the desktop clock overlay. PoHtimer runs silently in the background — your PC will act exactly when you told it to.
BATTERY RULES

Set rules that automatically protect your battery and your work — no timer needed.

🔋 Low battery → Hibernate

FAQ

Common questions.

Is PoHtimer really free? +
Yes, completely. PoHtimer is free and open source under the MIT license. There are no premium tiers, no in-app purchases, no ads, and no usage limits. You can even self-host and build it yourself from source.
Does it send any data to the internet? +
The only network request PoHtimer makes is a periodic check to latest.json on this website to see if a new version is available. No usage data, no analytics, no crash reports are sent anywhere. Ever.
Will battery rules work on my desktop PC? +
Battery rules only activate on devices with a battery — laptops, tablets, or desktops connected to a UPS. On a standard desktop PC without a battery, the Battery tab will show 0% and rules won't fire. This is correct behavior.
Can I cancel a power action once a timer fires? +
Yes. By default, PoHtimer shows a 5-second countdown dialog with a Cancel button when any action is about to execute. You can also disable this confirmation in Settings if you want instant execution.
Does it run when Windows starts? +
Optionally. In Settings, enable "Start with Windows" to launch PoHtimer automatically at login. Pair it with "Start minimized" to have it launch silently as the desktop clock overlay — your timers and battery rules will be active from the moment you log in.
How do I uninstall PoHtimer? +
Go to Windows Settings → Apps → Installed apps, find PoHtimer, and click Uninstall. Alternatively, use the Add or Remove Programs control panel. The uninstaller removes all app files cleanly — no leftover registry keys or folders.
I see a Windows SmartScreen warning. Is this safe? +
Yes. SmartScreen warnings appear for any app from a new publisher that hasn't yet built a reputation with Microsoft. PoHtimer is open source — you can audit every line of code on GitHub. To proceed: click "More info" then "Run anyway." The warning disappears as more users install the app and Microsoft builds a trust score for the publisher.
Can I contribute or report bugs? +
Absolutely. PoHtimer is built with Tauri 2 + React + TypeScript + Rust. Open a GitHub issue for bug reports, feature requests, or questions. Pull requests are welcome — the codebase is structured for easy contribution.
