GeoTapp vs Blink: time tracking or certification?
Blink is Germany's #1 software for building cleaning. GeoTapp certifies every job with anti-spoofing GPS, cryptographically sealed photos and client-verifiable reports.
Bottom line:
Blink excels at time tracking and team communication for cleaning. But GPS is not verified (no anti-spoofing), photos are not cryptographically sealed and reports are not independently verifiable. GeoTapp fills exactly these gaps.
GPS check-in is not GPS verification
Blink compares GPS position with the preset work location. But if an employee spoofs GPS with a free app, Blink doesn't detect it. GeoTapp uses anti-spoofing technology that cross-references multiple signals. Plus every photo is sealed with a cryptographic hash chain.

FAQ
What is the main difference between GeoTapp and Blink?
Blink is Germany's leading time tracking software for building cleaning: GPS, QR code, NFC, task management and team communication. GeoTapp goes further: it's a certification system that documents every job with anti-spoofing GPS and cryptographically sealed photos. The client verifies the report independently.
Does Blink have anti-spoofing GPS?
No. Blink compares the GPS position with the preset work location but does not verify if the position is real or spoofed. GeoTapp detects spoofing attempts.
Can the client verify Blink reports?
Blink generates internal reports. GeoTapp generates reports with a cryptographic seal that clients can independently verify on a public portal.
Blink is #1 in Gebäudereinigung. Why choose GeoTapp?
Blink excels at time tracking and team communication for the German cleaning sector. But if you need to prove to your client that the service was performed with tamper-proof evidence, you need GeoTapp. Different tools for different problems.
