Volero: Bike Computer GPS

Speed, climbing, heart rate zones, training form, and a maintenance log for your bikes – one app, entirely on your iPhone. No account. No subscription. No cloud.

You want to ride – not create accounts, compare subscriptions, or upload your data somewhere. Volero is the bike computer on your iPhone: precise GPS tracking, heart rate zones, training form, and a full maintenance log for your bikes. Everything stays local on your device.

YOUR RIDE, DOWN TO THE METER

• Second-by-second GPS recording – filtered so noise never distorts your route
• Reliable background recording with no gaps at traffic lights
• Pauses don't count toward your ride time – your average stays honest
• Elevation gain with smart smoothing: real climbs instead of phantom meters
• Live gradient in percent, calibrated right on the handlebar

A COCKPIT YOU CAN READ AT SPEED

• Big speed display, ride time and distance at a glance
• Live heart rate with zone color when a sensor is connected
• The map can rotate with your direction of travel – just like Apple Maps
• Light and dark map styles, with OLED-friendly true black at night

STRUCTURED TRAINING – NO SUBSCRIPTION

• Pairs with any Bluetooth heart rate monitor (chest strap or armband) and reconnects automatically
• 5 heart rate zones, analyzed automatically for every ride
• Training load per ride using the established Edwards TRIMP method
• Fitness and form curves (PMC): spot building phases, peak form, and looming overload
• Calorie estimates based on heart rate or speed

YOUR YEAR AT A GLANCE

• Dashboard for week, month, 6 months, or year – always compared to the previous period
• Activity heatmap: one cell per day, colored by distance ridden
• Personal bests: longest ride, most climbing, fastest average, top speed, highest heart rate
• Every ride in detail: scrubbable elevation profile, speed gradient along the route, zone distribution, start and end address

YOUR BIKES, YOUR MAINTENANCE LOG

• Manage any number of bikes – road, gravel, MTB, e-bike – with photo and full specs
• The odometer updates automatically with every ride
• Maintenance log with 11 types, from chain lube to full service, including costs
• Due-date suggestions by distance or time – never miss a worn chain again

BUILT FOR REAL-WORLD RIDING

• Crash protection: if iOS kills the app, your ride isn't lost – just resume or save it on the next launch
• Three sensor profiles from Precise to Eco so your battery lasts the really long rides – switchable mid-ride
• Optionally, every ride lands in Apple Health as a workout

YOUR DATA BELONGS TO YOU

• No account, no server, no tracking, no ads
• Everything stays local on your iPhone and is included in your iCloud backup
• One tap in Settings deletes everything – completely

Volero is available in English and German, with metric and imperial units.

Get on. Ride. The rest takes care of itself.
