678KKBeat

678KKBeat is an offline timer app for everyday timing tasks.

Use the stopwatch for start, pause, split, and reset sessions with clear lap tracking. Each split keeps both lap time and total time, and the app preserves your session state if you leave and return later.

Use the countdown timer to set a target duration from 1 second up to 99 hours. You can name a timer, pause it, add one minute, restart it, and receive a visible end alert with optional sound and vibration.

Use the interval flow for multi-stage timing plans. Build flows with 2 to 12 stages, assign a name and duration to each stage, add a short prompt, and repeat the full plan from 1 to 50 loops. Stage history is kept so you can review completed and skipped stages later.

The home screen highlights active timers and lets you open each one quickly. Saved presets can be copied, renamed, reordered, archived, and reused. Timer records can be closed, restored, or deleted one by one.

Preferences let you control the default sound, vibration, end reminder, screen-on behavior, theme, and text size. The app keeps its data on the device and does not require an account, cloud sync, ads, or network access.
