Jolt Cycling vs GPS Bike Computer

Jolt turns your iPhone into a heart rate zone computer for cycling. Big, glanceable numbers show your live heart rate, current zone and time in zone, so you can hold Zone 2 on endurance days and actually hit your intervals on hard days. No head unit needed. WHY JOLT On a training ride you shouldn't juggle a navigation app, a workout tracker and a kitchen timer. Jolt puts heart rate, route and fueling on one dark, sunlight-readable screen built for quick glances at 30 km/h. TRAIN BY HEART RATE ZONE - Live heart rate from a Bluetooth chest strap or your Apple Watch - Current zone, percent of max and time in every zone, always visible - Zones based on your max heart rate, fully configurable - Colour-coded and readable in direct sunlight FUEL ON TIME, EVERY RIDE - Set an interval (for example every 30 minutes) and get a clear alert when it's time to eat - Track carbs per hour against your target - Never bonk on a long ride because you forgot to eat FOLLOW ROUTES WITHOUT CLUTTER - Import any GPX route from Komoot, Strava, RideWithGPS and others - One clean line on the map: no POI pins, no feed - Elevation profile shows the climbs ahead and distance to go - Search for a place and ride there, with a quiet re-plan if you drift off the line RIDE WITH YOUR GROUP - Join a group ride from a 6-character code or a QR link - See your teammates' live heart rate zones on your own screen - Pace the group together instead of guessing who is buried TRACK EVERY RIDE - Speed, distance, elevation, moving time and laps - Workouts saved to Apple Health - Export any ride as a GPX file via the share sheet BUILT FOR REAL RIDES - Designed for 1 to 4 hour training rides - High-contrast dark interface, easy on battery, easy to read in sunlight - Big, glove-friendly controls - Works offline once your route is loaded WHAT JOLT IS NOT No social feed, no segments, no ads. Jolt does one thing: it keeps the numbers that matter in front of you while you ride. WORKS WITH Bluetooth heart rate straps (Polar, Wahoo, Garmin and other standard BLE straps) and Apple Watch. Requires iOS 18 or later. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://joltbike.app/privacy
