Distance - Bike Parts Tracker

Distance records your road bike rides and tracks how far each part has been used.

Just enter the date and distance of each ride. Distance adds it up for your chain, cassette, tires, brake pads and more, and the progress bar turns red when a part reaches its replacement distance.

■ See every part's distance at a glance • Ride distance since the install date is calculated automatically for each part • A progress bar shows how close each part is to its replacement distance and turns red when it's due • Parts are grouped into categories like Gears, Chain, Tires & Wheels and Brakes • For parts already in use, enter the distance so far and counting starts from there

■ Easy replacement records • Tap "Replaced today" to reset a part's distance. The previous distance stays in the history • Swapped a part mid-day? Rides are split between the old and new part by the time they were logged

■ Look back on your year with charts • Bar charts of your distance by month and by year • See distance by bike and by part, like how far your chain or tires went this year • Tap a bar to narrow it down to that month

■ Indoor trainer and other bikes • Choose parts that a ride shouldn't count for (like your road tire on trainer days) • Log distance for a part alone, without the bike (e.g. you rode the wheel on another bike you don't track, or used another tire on the trainer)

■ Add parts in bulk and customize freely • Check parts in the list and add them all at once • Set up a new bike with "Same as …" to copy another bike's parts • Edit the categories and parts list freely — you can even make one for a motorcycle

■ Multiple bikes • Rides and parts are kept separately for each bike • See total distance, this month's distance and the total for all bikes

■ No account. Your data stays on your device • No sign-up or login • Your data is stored only on this device and is never sent anywhere • Back up to and restore from a JSON file
