## What is Vumble?

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.

## Version history (last 3 releases)

### 1.0.2 — 2026-10-15

With location access set to “Always”, the blue location indicator is gone. Vumble now records your bike rides more reliably, even if you closed the app beforehand. Numbers are never cut off anymore, and the privacy policy has been updated to version 1.4.

### 1.0.1 — 2026-10-05

Delete all data: You can now remove all trips, statistics and settings from your device with one tap in your profile.

A rest day for your streak: Once every seven days, a day can be missed without ending your streak.

Vumble counts from the moment you switch it on. Movement from before is no longer read in afterwards.

Steps are now calculated from walking only. Comparison values have been revised and are marked where they are estimates.

Easier to read: higher contrast, support for large text and VoiceOver.

Onboarding no longer asks for permissions you have already granted.

### 1.0 — 2026-09-30

No release notes.
