I tried the application and I'm pretty impressed with what Sylo team has created. Of course it's not the full version so will be waiting for it.
Well it kinda is the full version of the current app. The current one is a full functional partially decentralized comms app, the upcoming DApp is fully decentralized with more features.
Agreed, the current version of Sylo is a fully working app that I use daily. Waiting to hopefully use the beta of the DApp soon.
