(SECUSO) Counts your steps in the background. Customize daily goals.
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.

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.secuso.privacyfriendlyactivitytracker is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 3.1.1 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Pedometer (PFA) first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Pedometer (PFA), and a listing is removed when the evidence for it stops holding up.
