ChainLife
ChainLife is a free web app that counts the km, hours and days on every component of your bike from your Strava or Garmin rides and tells you when each part needs service.

Example values
Every ride that comes in from Strava or Garmin adds km and hours to the parts of the bike you used.
The middle screen is the real ChainLife app on a phone.
Connect Strava or Garmin, or log rides by hand. From there, it works like this:
Tap a part, pick the model from the catalog, and it comes with a replacement interval that you adjust to what the manufacturer or your mechanic recommends.
Cleaning, service or replacement: check the parts from the visit and what was done, and the right counter on each one goes back to zero.
The reminder shows up on your dashboard, by email and on your phone. Replaced it? Log the replacement, and the new part starts from zero.

Not everything on a bike wears with distance.

Example values
Chain, cassette, chainring, tires, brake pads
Chain wear tracking: a chain stretches with use, so when to replace a bike chain depends on the km it has ridden.
Fork and rear shock
Suspension service is scheduled in hours of use, not km.
Tubeless sealant, brake fluid, cables, headset, bottom bracket
Sealant dries out and brake fluid ages even when the bike sits still.
All three run at once. Whichever runs out first sends the reminder.

Lucas Trindade, cyclist and creator of ChainLifeI tracked my bike maintenance in my head and in a spreadsheet that was never up to date. By the time I remembered to check the chain, it was already past due.
I built ChainLife to stop guessing. It runs on my bikes and on the bikes of everyone in the beta, and every change comes from what we see on the trail.
