Most riders don't forget how to wax. They forget when they last did it. Loom tracks your chain by distance rather than by feel. Every bike carries an odometer, and every wax event saves a snapshot of it. The distance since your last wax, how much of its expected life you have used, and whether you are overdue all come out of those two numbers. IT LEARNS YOUR INTERVAL Loom starts at 186 miles for hot wax and 93 miles for drip lube. After two wax events it switches to a rolling average of your own history, so the number follows your roads and your weather rather than a figure off a bottle. It warns you at 80%, and again at 100%. RIDES WITHOUT THE TYPING Connect Apple Health and your cycling workouts become rides on their own — date and distance, nothing else. Strava is there if that is where your riding lives. Neither is required: type a distance and Loom works exactly as well with no connection at all. MORE THAN THE CHAIN Chains, tires, sealant and service run off the same odometer. Set an interval, log a change, and Loom counts the distance down. TIRE PRESSURE Tell Loom your weight, your tires and your roads, and it gives you a front and a rear pressure, each with a good range either side. It respects hookless rim limits and your tire's printed maximum, says what set the number, and saves setups to each bike. Road, gravel and cyclocross, in psi or bar. ON THE HOME SCREEN A widget carries wax life at a glance, so you find out in the kitchen rather than in the garage. YOUR RIDING HISTORY IS YOURS No account to create, no Loom server, no analytics, no third-party SDKs, and no tracking. What you log stays on your iPhone and, if you use iCloud, in your own private iCloud database — where Loom cannot read it either. Apple Health and Strava are optional and read-only; Loom never writes anything back to either. ALL OF IT, FREE Every part of Loom is free: as many bikes as you own, automatic ride import from Apple Health or Strava, component tracking, the tire pressure calculator, the widget, and the full Statistics tab — averages, the timeline, which product lasted longest, and when the next wax is due. No subscription, no in-app purchases, no ads. Privacy Policy: https://loomwax.ridetogether.io/privacy.html

Verdict

The call

The clearest difference is in-app purchases: SIGMA LINK at none against Loom Cycling's 1. SIGMA LINK also leads on device support (3 vs 1) and iOS requirement (12.0 vs 18.0). Loom Cycling's advantage is update cadence (every 9 days vs every 4 months). On price and ads there is nothing between them.
