Certisign SignApp Review

Certisign SignApp is a free Android app developed by Certisign Certificadora Digital S.A. It falls under the Business & Productivity category. This app allows users to sign documents online using their mobile or tablet device. It offers two options for signing documents, either by spelling out your signature on the screen or by using an A1 digital certificate. SignApp collects evidence such as IP address and geolocation, which gives legal validity to the signed document. Each document signed generates a protocol that can be used to check the signature and evidence.

Overall, Certisign SignApp is a useful and convenient tool for signing documents on the go. The app is user-friendly and straightforward, making it easy for anyone to use. It's worth noting that the app does require an internet connection to function properly. For more information on how to use the app, users can visit the CertiSign channel on Youtube or the Certisign blog.
