Cycling and getting rewarded for itβtoo good to be true? Then Radbonus is perfect for you! With Radbonus, you can track your cycled kilometers and cycling days, earning attractive bonuses to motivate you to ride more. In cooperation with our partners, we challenge you to participate in challenges, battles, and missions. The rewards vary and include fixed prizes (everyone who completes the challenge gets the prize), raffles (everyone who completes the challenge is entered into the draw), and discounts. Challenges Challenges give you the opportunity to earn rewards by reaching a specified kilometer goal. Want to pursue your own goals? You can now do so with the new Radbonus feature. Create a custom goal, whether it's a certain number of cycled kilometers, CO2 savings, calories, or saving money for a financial goal (e.g., a new rain jacket for β¬70). Do you love measuring your performance against others? Then individual and team battles are just for you. Besides the existing battles, you now have the option to invite up to 10 friends to a private battle, where you compete on a leaderboard. You can set a fixed time frame or a kilometer goal. With a prize for the winner, the motivation to pedal hard is even higher! Is community important to you? Then you can collect kilometers together in missions. Tracking kilometers Tracking your kilometers is easy: just press "Start" at the beginning of your ride and "Stop" when you arrive. During the ride, location services and motion sensors help accurately measure your distance. Donβt worry, your data remains completely anonymous, and we do not receive any geo-data from you. For those interested in diving deeper into data protection and tracking, more details are available. And by the way, no cheating allowed! A clever little algorithm helps us instantly spot any non-cyclists. Exclusive Partner Actions Additionally, there are exclusive worlds accessible only to participants with a partner code. These participants can take part in exclusive challenges and battles, where the rewards are only available to them. There's also the option to cycle against teams or work together to complete a larger mission. You can enter the access code directly during the app onboarding or later under the "Access Code" navigation option. Additional Features Save your favorite challenges so they always appear at the top of your overview. To have your cycling kilometers from other apps rewarded by Radbonus, you can easily connect the Radbonus app with your smartphone's Health app. In the settings, you have the option to switch between light and dark mode, learn more about Radbonus's mission, and adjust various other settings. At Radbonus, we make sure you get what you want! To avoid missing any new challenges, feel free to follow us on Instagram, Facebook, and Twitter. Apple is not involved in the Radbonus program in any way.

Vumble spots your everyday trips automatically β 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 COβ 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 - COβ 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 COβ 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.
