What Certisign SignApp actually does (from store listing)
The SignApp app makes it possible to sign documents online – anytime, anywhere.
Sign any document with your signature spelling on the mobile/tablet screen, or use an A1 digital certificate.
The application collects the evidence (IP + geolocation) giving legal validity to the signed document.
Each document signed in SignApp generates a protocol in which the signature and evidence can be checked.
