In short
Chainline: Bike Maintenance tracks wear on the parts of every bike you own, including chains, tyres, brake pads, and suspension service. It works offline with no account, can import rides from Apple Health, and lets you move a part's distance to another bike. Its standout detail is a colour-coded bar that shifts from amber to red as a part nears replacement.
Summary by Debuts, based on the App Store listing.About
Chainline keeps track of what wears out on every bike you own — and tells you before a worn chain eats your cassette.
EVERY BIKE, EVERY PART • Chain, cassette, chainrings, tyres, brake pads, sealant, cables, bar tape, suspension service, bearings • Wear by distance or by time, with a bar that turns amber when a part is due and red when it's time to replace • Starting limits for each part that you can change; check real wear with a chain checker too
NO ACCOUNT NEEDED • Enter rides or set the odometer from your bike computer • Or import cycling workouts from Apple Health — Apple Watch, iPhone, or apps that save to Health • Nothing leaves your iPhone
FOR THE WHOLE FAMILY • Every bike in the garage, kids' bikes included • Replace a part in one swipe — the service is logged for you • Move a part to another bike and its distance comes with it
CHAINLINE PRO — ONE-TIME PURCHASE One bike with every feature is free. Pro adds unlimited bikes, moving parts between bikes, and CSV/backup export. Pay once — no subscription.
