About the app

Every review in Guest Note Club is tied to a verified stay. The app checks the property’s wifi network to confirm the guest is on site, and without a match there is no certification badge. That single check removes reviews written from a competitor’s office or a reviewer’s sofa.

Reviews are never public. They go to the host and to your own followers, and nowhere else. With no public audience there is no leverage for a guest threatening a bad score, and no reason to exaggerate. What you browse instead is a map of places reviewed by people you actually know.

Feedback can be sent during the stay rather than after checkout, so a broken sink gets reported while it can still be fixed. Hosts who resolve an issue quickly get visible credit in the review.

The story

Public review scores created an economy nobody wanted: fake positives, competitor sabotage, and guests using the threat of a one-star as a bargaining chip at check-in. Guest Note Club removes the public score entirely, which removes the leverage along with it, and replaces the anonymous stranger with someone you follow. The wifi check is the cheapest honest proof of presence available, and it needs no extra hardware from the host.
