Why KsBatchTimer
Focused on doing one thing well: batch timing.
Multiple stopwatches at once
Run several stopwatches on one screen — start, pause, and reset each independently. Training rounds, multi-burner cooking, or lab logs, all in parallel without interference.
Countdowns that remind you
Duration countdowns and target-date countdowns, with notifications, vibration, and alert sounds on finish — four sounds to choose from, so no milestone slips by.
Offline & privacy first
No account, no ads, no network. Everything is stored only on your device, nothing is ever uploaded, and uninstalling deletes it all for good.
Live Activities on iOS
Your timing progress lives on the Lock Screen and Dynamic Island — glance to check, no need to unlock and open the app.
Start timing in parallel
Download KsBatchTimer — no sign-up, no network, every timer in one glance.
Questions?
Is KsBatchTimer free?
Completely free: no in-app purchases, no subscriptions, and no ads — every feature is unlocked.
Where is my data stored? Does it sync to the cloud?
It does not. All data is stored locally on your device and never uploaded to any server. Because of that, uninstalling the app or switching devices loses the data permanently — please keep that in mind.
Why is there no account?
KsBatchTimer is an offline-first, privacy-first tool: it works the moment you open it, with no account and no network required.
Which platforms and languages are supported?
Available on both iOS and Android. The interface offers 10 languages: 简体中文, 繁體中文, English, 日本語, 한국어, Deutsch, Español, Français, Português, and Русский.
How accurate is the timing?
Great for everyday scenarios like cooking, workouts, study, and work sessions. Accuracy is affected by device performance and system scheduling, so it should not be the sole instrument for high-precision professional measurement.
