## What is Watch Rate Log?

Track how fast or slow each mechanical watch runs, then keep the readings in one clean offline log.

Use it to:
- enter observed fast or slow seconds over a measured elapsed time
- convert each reading into seconds per day
- compare dial up, dial down, crown up, crown down, and worn positions
- keep beat error, amplitude, and service notes beside each check
- review average rate, positional spread, best rest position, and service flags
- export a CSV for your archive or a watchmaker handoff

Why people buy Watch Rate Log:
- faster than rebuilding a watch spreadsheet
- more structured than a notes app
- clear about manual logging instead of claiming automatic microphone diagnosis
- useful before regulation, service, sale, or daily wear rotation decisions
- paid once, fully offline

Watch Rate Log is a manual logging utility. It does not listen to the watch, diagnose a movement, replace a qualified watchmaker, or guarantee service decisions.
