Vumble spots your everyday trips automatically — on foot, by bike, bus, train or car. No start button. Put your phone in your pocket and go. From that, Vumble makes two numbers: how much CO₂ your trip caused compared to driving, and how many active calories you burned along the way. A MASCOT INSTEAD OF A TARGET Vumble has five energy levels, from Snoozing to Glowing. Move a lot and he perks up. Move little and he gets sleepy. That's all that happens. No red numbers, no missed goal, no nagging. YOUR DATA STAYS WITH YOU No account. No server. No ads. No subscriptions. Everything Vumble measures sits on your phone and goes nowhere else. The app is free and works without signing up. WHAT VUMBLE SHOWS - CO₂ compared to driving, day by day and across the week - Active calories, translated into trees and cookies - Your streak: days you got moving - Your week as a tappable story CO₂ figures are based on emission factors from the German Environment Agency (TREMOD 6.71B, reference year 2024). Vumble needs background access to your location so it can spot trips without a start button. Your location never leaves your device.
