This app is not supported on Android tablets. If you need to use it on a tablet, you will need to get an iPad. If Android tablets were supported, my rating would be 5 stars. The security is very good and the features are almost on par with other popular messaging apps. Aside from tablet support, the only thing missing is the ability to edit messages that have been sent. With the huge migration of users from other apps in 2021, Signal should make Android tablet support a high priority.
