What is Geer?
Geer tracks the wear on every component of your bike so you know when the chain, cassette, or brake pads are due before they fail. Connect Strava once and every ride you record gets attributed to the right bike automatically, with mileage flowing down to the individual parts. Their own line sums up the split: Strava tracks your rides, Geer tracks your parts.
It's a progressive web app rather than an app-store download: you install it to your home screen from the browser (iOS 16.4+ and Safari only, Android 8.0+ with Chrome 72+), and it adds to the dock on a Mac too. The company behind it, GEER BIKE OÜ, is registered in Tallinn, Estonia and run by two founders, Ron and Mateus. It's funded by subscribers rather than investors, and its privacy policy says it runs on renewable-powered servers in Germany.
Pro is priced as €1.67 a month billed yearly. Geer doesn't publish the annual total anywhere on the site, only the monthly figure and a 17% discount against paying month to month.
Key Features
Whole-bike setup
Answer a few questions about a bike and Geer suggests a maintenance plan for every part, added in one tap. New riders get a personal plan built from their Strava rides when they sign up, and the suggested intervals include presets for chain lube, tire checks and suspension forks.
Component wear tracking
Distance-based wear on chains, cassettes, brake pads, and anything else you install, with a color-coded dashboard showing each part's status at a glance.
Maintenance alerts
Push and email notifications when a component hits its service interval, so upkeep gets prompted instead of remembered.
Real-time Strava sync
New rides arrive the moment they upload to Strava, and edits to an activity's title, type or privacy (plus deletions) come through in real time too. One documented gap: changing only the bike on a Strava activity doesn't trigger an update, which Geer attributes to Strava. A full sync runs daily at 6pm to catch anything missed, and you can trigger one manually. A paid Strava subscription is not required.
Component swapping
Install, swap, and deinstall parts across bikes. The wear history follows the part, which matters if you move a power meter or wheelset between bikes.
Service history
A full maintenance log per bike and per component, replacing the spreadsheet most riders eventually abandon. Logging a service shows how far you've ridden since the last one and how often the task is due.
Indoor and outdoor parts
Mark a part as indoor, outdoor or both and wear is counted only where it happens. Zwift-style virtual rides and trainer rides tagged as indoor in Strava both count as indoor.
Who It's For
- Riders with multiple bikes juggling wear across a fleet
- High-mileage cyclists who go through chains faster than they track them
- Anyone who'd rather ride than manage maintenance (the app's stated audience)
Does Geer need a paid Strava subscription?
No. It works with any Strava account. Rides sync automatically over Strava's API, and the Strava data Geer stores is limited to your bikes, activity IDs and authentication tokens, not the rides themselves.
What happens if I downgrade from Pro?
Nothing gets deleted. If you're already inside the free limits (2 bikes, 5 components) nothing changes at all. If you're over them, tracking pauses until you hide a bike or delete a component to get back under.
Why isn't it in the App Store?
Geer is a progressive web app: you install it from the browser to your home screen. Same install on iOS, Android, and desktop, no store account needed.
Is there a way to get Pro without paying?
Their referral program gives a free month of Pro per referred friend, and Pro for life after ten. A referral only counts once the friend has verified their email and added at least one component.
