I would say yes. You download the app (playstore, appstore or fdroid), install it. Then on first time opening it you need to choose a pin for the app and an username for your first profile. Then you can start chating. The gui is pretty similar to signal. And it works pretty good so far. I had problems with calls last time I tried (but a few month back it worked).
