A bike maintenance log,
because crisp shifting is not luck.
Chain lube by distance, suspension by ride hours, chain wear before it takes the cassette with it. Every bike in the garage on its own schedule.

WHY RIDERS USE IT
Bike maintenance you can feel in every shift
Crisp shifting is maintenance you already did. Chain lubed every 150 miles, sooner when it is wet, because a dry chain wears the whole drivetrain. Chain checked twice a year and replaced at 0.5% stretch, so the cassette and chainrings live to see another season. Brakes and cables checked with it. A full tune-up yearly — bearings, derailleur, wheel true, bolt torque. Sealant refreshed twice a year whether or not you have ridden. Suspension comes due on ride hours, 50 on the fork and shock, not on the calendar. Nothing surprises you at mile forty.
WHAT YOU TRACK
A service record per bike, in bike words
Pick the bike type and the app keeps it simple: services and service records, a drivetrain and two wheels, and nothing borrowed from a car.
- The thing
- BikeGrouped into your Garage, each with its make, model and frame number.
- Something is wrong
- IssuesA creak, a rub, anything not working right — with a photo, so the shop sees what you heard.
- Something recurs
- ServicesChain wear checks, brake bleeds and other recurring service, due by distance, hours or date.
- Something was done
- Service recordsA chain replacement, a brake bleed, a bearing press — with the receipt attached.
- Who did it
- PeopleYour shop, your riding partner, or you at the workstand.
- What it is made of
- PartsThe drivetrain, and front and rear wheels with their normal PSI.
A down issue must be fixed before riding, and it stays at the top of the list until it is.
STARTER SCHEDULE
The service intervals, already set
Add a bike and these come with it. Tighten the intervals for winter miles, loosen them for a dry-season commuter, or turn off what does not apply.
| Service | Comes due | Why |
|---|---|---|
| Lube the chain | 150 mi | More often in wet or dusty conditions. A dry chain wears the whole drivetrain. |
| Check chain wear | 6 months | Replace at 0.5% stretch before it takes the cassette and chainrings with it. |
| Check brake pads & cables | 6 months | Pad thickness, cable fray, hydraulic feel. |
| Full tune-up | 12 months | Bearings, derailleur adjustment, wheel true, bolt torque. |
| Refresh tubeless sealantOff by default | 6 months | Tubeless tires only. Sealant dries out whether or not you ride. |
| Suspension serviceOff by default | 50 ride hours | Fork and shock, per the manufacturer’s hour interval. |
Recommendations, not authority. Anything else is a service you add with your own interval — a bearing refresh after a wet winter, a dropper post service, a pre-race check.
READINGS
Two meters, because bikes wear two ways
Distance and ride hours
Chain lube is a distance job. Suspension is an hours job — forks and shocks are specified in hours, and a slow technical season puts far more hours on them than the mileage suggests. A bike keeps both readings, and each service comes due against the one that actually describes its wear.
Or simply the calendar
Sealant dries and cables corrode whether you ride or not, so those recur on dates. Every service can use distance, hours, the calendar, or whichever comes first — with due-soon reminders before the ride rather than during it.
SETTING ONE UP
What it asks for, and nothing it does not
The bike
Make, model and frame number. The frame number is worth having for exactly one reason, and it is the reason you hope never to need it.
What hangs off it
The drivetrain, and the front and rear wheels — each with the normal PSI you run, recorded where you will actually look for it rather than on a sticker under the rim tape.
Is this for bicycles or motorcycles?
Bicycles — road, gravel and mountain. The starter schedule is chain wear, brake checks, tune-ups and suspension service. Motorcycles use the vehicle type instead, which tracks the odometer, oil changes and chain final drive.
Can a service come due on ride hours instead of distance?
Yes. A bike keeps two meters — Distance and Ride Hours — and a service can recur on either, on the calendar, or on whichever comes first. Suspension service is the usual case: forks and shocks are specified in hours, not miles.
Can I track more than one bike?
Yes. Each bike is its own record with its own distance, ride hours, wheels and schedule, grouped into your Garage. The trail bike and the commuter never share a chain interval.
Will it tell me when the chain is worn?
It reminds you to check. Chain wear is a recurring service every 6 months — replace at 0.5% stretch, before it takes the cassette and chainrings with it — and you log the check against the bike so the next one is scheduled from it.
