About muzutozvednout.cz

Můžu to zvednout (muzutozvednout.cz) operates a mobile app that identifies unknown incoming phone numbers by checking them against a database of numbers rated by users. If a number has a negative rating, the app warns the user or, if the user chooses, blocks the call.

The app is aimed at individual consumers in the Czech Republic who receive unwanted marketing and fraudulent calls. The website describes the database as receiving roughly 30 thousand new ratings per day and presents the service as free for users; no pricing or revenue model is stated. The site also publishes a consumer-education section on avoiding phone scams and links to the Czech Republic-focused content.

The website lists a sister service for Germany at sollichannehmen.de and shows a list of supported countries including Slovakia, Poland, Hungary, Austria and others. The input does not state the founding year, headquarters, office locations, funding or hiring.

Product: Mobile app that identifies and blocks spam and scam phone calls based on a user-rated phone number database.
