Beat Rate — a quiet log for the watches you service
Most of what we write about here is a number: amplitude in degrees, beat error in milliseconds, rate in seconds a day. Beat Rate is the app version of the same notebook — a place to log those numbers against a specific watch and see the trend, instead of remembering it.
Six things Beat Rate keeps track of
Amplitude log
Record dial-up, dial-down, and both crown positions after every service, and watch how the arc changes over months.
Beat error history
Track beat error before and after adjustment, per movement, so you can see whether a fix actually held.
Rate by position
Six-position rate entries laid out on one card, with the spread between best and worst position calculated automatically.
Service journal
A simple entry per service — date, what was done, which oils were used — attached permanently to the watch.
Multiple watches
Keep a separate card for every movement you own or service, each with its own history and notes.
Private by default
Entries live on your device unless you choose to back them up. No public profile, no feed, nothing to share.
Beat Rate doesn't grade your watch or tell you what to buy. It just keeps the numbers where you can find them again.
From reading to record in three steps
Take a reading
Use a timegrapher, an app-based acoustic reading, or your own count against a metronome — Beat Rate doesn't care which.
Log it against the watch
Enter amplitude, beat error, and rate under that watch's card, with the date and position noted.
Watch the trend
Over several services, a slow drop in amplitude or a growing positional spread becomes visible instead of anecdotal.
Mini FAQ
1 Does Beat Rate diagnose problems for me?
No. It logs the numbers you enter and shows you the trend across services. Interpreting a reading is still on you or your watchmaker.
2 Do I need a timegrapher to use it?
No — some entries come from a shop's printed report, others from an estimate. The log is only as precise as what you put in.
3 Is my data shared anywhere?
Entries stay on your device by default. See our privacy policy for the optional backup details.
