MTB Setup Tracker - BouncyBits

BouncyBits is the MTB suspension setup tracker that lives in your pocket. Track fork, shock, and tyre settings for every bike you own and every setup you ride. Bike park, local trails, specific race tracks, wet weather; switch between setups in seconds. Built for home mechanics, parents wrenching kids' race bikes, and anyone who's ever forgotten where they wrote down their suspension setup.

BUILT FOR REAL BIKES
No matter what you ride, BouncyBits adapts to your hardware: hardtails or full-suspension bikes, air or coil shocks, and the actual click counts your specific fork and shock provide.

AS MANY SETUPS AS YOU NEED
Park, trail, race day, wet weather — save them all per bike. Never lose your baseline setup when you tweak for an uplift day. Flip between setups instantly.

COMPARE TWO SETUPS SIDE BY SIDE
Directly compare two setups from the same bike and instantly see differences. Make changes directly in the side-by-side view.

TRACK ONLY WHAT YOU CARE ABOUT
Add custom fields to any component. Extra clickers, air chambers, after-market volume reducers — whatever your hardware has. Hide the standard fields you don't use.

FORK, SHOCK AND TYRE TRACKING
Track air pressure, sag, HSC, LSC, HSR, LSR, spring rate, volume reducers, and tyre pressures. Save clicks from open or closed. Store tyre pressure in PSI or bar. Your settings, stored how you like to read them.

SETUP HINTS IN YOUR LANGUAGE
Built-in reminders explain what each suspension setting does and how changes feel on the trail.

REFERENCE INFO WHEN YOU NEED IT
Write reference notes for any bike component in settings — manufacturer recommendations, service intervals, tuning tips — then pull them up directly from the setup card while you're actually making adjustments.

NOTES WHEREVER YOU NEED THEM
Add notes to any bike, setup, or component. Keep your insights right where the settings live.

SHARE SETUPS AND BIKES
Send a single setup or a whole bike to anyone as a link. The recipient can either import it into their own BouncyBits app, or just view the data if they don't have the app. You can also create a setup card and save it to your photos for a shareable offline snapshot.

BACK UP AND RESTORE
Changing phones or worried about your data? Back up to a file you store wherever you like, or directly to iCloud.

PRIVACY FIRST
Everything is stored locally on your device. No account. No tracking. No ads.
Data in backups and shared links is completely in your control, and is never seen by us. If you delete the app, the data on your device is gone with it (so do a backup first!).

WORKS OFFLINE
Perfect for the trailhead, the bike park, or anywhere else there's no signal. All your bikes and settings are always there.

FIVE LANGUAGES
Available in English, German, Spanish, French, and Italian. Automatically matches your device language.

DARK AND LIGHT THEME
Choose the theme that works for you. Switch between dark and light mode whenever you want.

COMPLETELY FREE
No in-app purchases. No subscription. No account required. Just a tool that helps you keep your bike dialled in.
