WristLog: Mechanical Watch Log

WristLog is a mechanical watch log and watch collection tracker. Log what you wear, track watch accuracy, measure your watches with the built-in timegrapher, and keep a full watch service log, all in one app. Use it as a watch tracker for your whole collection, from your first
automatic watch to your grail.

LOG WHAT YOU WEAR
- Log today's wrist check with one tap, or add past days in bulk.
- See your watch rotation on a calendar: most worn, least worn, and the watches that haven't left the box in months.
- Get a monthly recap of what you wore, ready to share.

TRACK WATCH ACCURACY
- Log how many seconds per day each watch gains or loses, measured against atomic time.
- Follow every accuracy run on a chart over days, weeks and months.
- Compare each watch to its movement's spec, including COSC chronometer limits, with service dates on the same chart.
- Quartz watches are tracked in seconds per month or per year.

BUILT-IN TIMEGRAPHER
- Hold your mechanical or automatic watch to the phone's microphone and measure rate, beat error and amplitude.
- Beat rate (bph) is detected automatically, or set it yourself along with the lift angle.
- Measure in different positions, like dial up or crown down, and compare them side by side.
- Check the condition of a used or vintage watch before you buy it.
- Own a timegrapher already? Add its readings and keep them with the rest.

WATCH SERVICE LOG
- Keep a service history for every watch: dates, watchmaker, cost and warranty.
- Note what was done: full service, regulation, new gaskets or crystal, water resistance test.
- See when each watch was last serviced and how its accuracy changed after.
- Get a heads-up from AI insights when a watch may need servicing.

PAPERS AND COSTS
- Store warranty cards, receipts and certificates with each watch.
- Track every other cost too: straps, batteries, repairs.
- Add purchase and sale prices to see collection value and cost per wear. Off until you turn it on.

YOUR WATCH COLLECTION
- Build a full watch inventory with photos, reference, caliber, movement and specs. AI fills in the specs from the model name.
- Add unlimited watches and keep a wishlist for your grails.
- Sold and archived watches keep their full history.
- Write about your watches in a diary, with photos.

SHARE
- Share images of a watch, your whole collection, your monthly recap or an accuracy run.
