Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 9.49 MB, so it installs quickly even on modest connections.
This build is signed by "SECUSO - Security Usability Society" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

Privacy Friendly Pedometer can count your steps in background, provides you an overview about your walked steps and allows you to define custom walking modes and notifications if the achievement of your daily step goal is in danger. The app requires minimal permissions (Run at startup and prevent phone from sleeping). It belongs to the Privacy Friendly Apps group developed by the research group SECUSO at Karlsruhe Intitute of Technology. More information can be found an secuso.org/pfa

Privacy Friendly Pedometer can count your daily walked steps while it runs in background. It gives you an overview about your walked steps, distance and about the calories you have burned while walking. You can add and choose different walking modes with different step lengths, such as walking or running, to improve the calculation of distance and calories.

In a special training mode you can track your training sessions. To each training session additional information, such as feeling or a description, can be added.

What makes Privacy Friendly Pedometer different from other pedometers?

1. Minimal amount of permissions:
* Run at startup: This permission is required to restart the step counting when your phone boots.
* prevent phone from sleeping: On some devices the processor falls asleep and prevents counting steps. With this permission the app can keep the processor awake while counting steps.

Most of Pedometer Apps in the Google Play Store require additional permissions. E.g. accessing the network or Internet which is mostly used to display advertisement. Some apps have access to GPS or telephony data.

2. No advertisement.
Many other free apps in the Google Play Store dazzle annoying advertising and also shortens battery life.
