Overtime Tracker 加班打卡记

Keep a reliable local record of overtime facts, including time, mode, location snapshot, photos, and your confirmation, inside a checkable chain you can export.

One-tap overtime records

Choose on-site, field, or remote mode, save start and end time, and see the result immediately.

Location and photo support

Location is read once only when you record or refresh, with visible accuracy. Attach up to four photos.

Calendar and statistics

Review daily duration and workload by day, week, or month, without pay calculation.

Hash chain and export

Each record joins an on-device SHA-256 chain with an audit trail. Export JSON or monthly PDF and import to deduplicate.

Important note

Overtime Tracker records facts and elapsed time only. It does not calculate wages, overtime pay, taxes, or legal outcomes. Data stays on your device by default, with no account, ads, or background tracking. Limited monthly backfill helps when you forget to log.

What if I forget to log?

Use the limited monthly backfill quota. Edits leave an audit trail and never silently overwrite records.

Do I need an account?

No. Records, settings, and exports stay on the device; JSON import is the migration path.

Does it calculate pay?

No. It records hours and date facts only; calculate amounts separately under your applicable rules.
