What’s the use?

App crashes constantly. Does not seem to work at all. Asks for your password repeatedly, even when you’re attempting a call.

Thanks Sylo!

Most people don’t understand how much information they are forced into trusting that it will be ok because there is no other option to communicate... now I don’t have to ‘trust’ that the most important details about me are safe in the internet clouds! Won’t send my social, tax ID, health info, etc unless sending via Sylo now. Messaging and calls have worked like a charm since I started using a earlier this year. Cheers!

I made an account and verified it and the app won't even log on. I even re downloaded the app. As far as I can tell this app is garbage. I can't even access it to see what it's like.
