Just view the substition plan
About this app
The vertretungsplan.io App allows to view the existing substitution plan at the mobile.
What does vertretungsplan.io not do?
- showing the substitution plans of all institutions - creating substitution plans - publishing substitution plans - tracking users
Advantage (compared to viewing it directly)
- notifications on changes/ background sync so that one does not miss the changes - offline support - the plans are downloaded and can be viewed without connection too - low maintenance - the access data and settings (if required for a school) are saved, it is not necassary to enter them again and again - optimized for small screens - the plan list is optimized for small screens (depending on the school, viewing the plan at a small screen is not comfortable)
Freedom
Everyone could setup his own server und use it with this App. The App and the backend are Open Source. You can find them at https://codeberg.org/vertretungsplan.
The substitution plans are created with proprietary software in most cases, and sometimes delivered by proprietary software. vertretungsplan.io allows viewing them without adding more proprietary components.

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 io.vertretungsplan.client.android 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, 1.5.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Vertretungsplan.io - free substitution plan App 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 Vertretungsplan.io - free substitution plan App, and a listing is removed when the evidence for it stops holding up.
