Security & authenticity

Security rating: Trusted

Signing certificate

Certificate issued to “zph-mph” Not the developer's name (“CHECKMAT P.C.”). Names in certificates can't be verified, so this alone proves nothing.
The same certificate signs apps from 175 different developers Developers sign only their own apps, so this almost always means the files were re-signed by someone else — often after being modified.
