Choose WatchMy.Bike if you want to showcase bike builds publicly, track cost per kilometre, and store receipts — and a browser-based workflow suits you. Choose Componentry for native mobile apps, four provider integrations, a predicted replacement date for every component, multi-dimension wear, and electronic shifting battery tracking.
WatchMy.Bike has genuinely differentiated features: public profile pages for sharing bike builds, a 30,000+ bike model catalog, cost-per-kilometre analytics, document storage for receipts and warranties, and an AI assistant integration via MCP. Its Steel tier is free forever, and its published comparisons of other apps — ours included — are notably fair. For cyclists who want to document builds publicly and track their costs, it's a thoughtful product.
WatchMy.Bike is genuinely good at retrospective analytics — cost per kilometre, service history, receipts and warranties. The wear tracking underneath is distance against thresholds you set, which their own FAQ describes plainly. Componentry adds the forward half: watts lost to contamination and chain stretch, a lifespan modelled from your terrain and weather, and a replacement date. These are two halves of the same problem, so it is worth knowing which half you actually want.
WatchMy.Bike is web-only: no iOS app, no Android app. For a tool whose job is showing component status after every ride, that matters — cyclists check their phone at the bike stand, not a laptop. Componentry is native on iOS and Android, with a full web app alongside.
Like most dedicated competitors, WatchMy.Bike connects through Strava exclusively, so Garmin, Wahoo, and Hammerhead riders reach it through the Strava relay — an extra hop, an extra account, and an extra thing to break. Componentry connects to all four platforms directly, so your rides land wherever they came from.
WatchMy.Bike tracks component wear by distance. Componentry tracks distance, moving time, and elapsed duration, enriched with weather data — because how far you rode is only part of what wears a component.
Di2, AXS, and EPS batteries aren't covered by WatchMy.Bike. Componentry tracks them alongside your mechanical components, with charge reminders based on your riding.

WatchMy.Bike's Alloy tier is €3.25/month or €39/year, with a free-forever Steel tier for up to 3 bikes — monthly billing arrived in 2026, and prices are close to Componentry's $4.00/month. The difference isn't price: it's native apps, four providers, predicted replacement dates, and battery tracking versus public profiles, cost analytics, and document storage. Pick by workflow.
There is no data lock-in to fight. Connect your Strava, Wahoo, Garmin, or Hammerhead account, add your bikes, and log each component once with its current mileage. From that point every ride updates your components automatically — nothing to migrate, nothing to maintain by hand.
Native iOS and Android apps. A replacement date for every component. Strava, Wahoo, Garmin, and Hammerhead in one place.
