Client is open source, but the server is not. So I would say Telegram as a service is not FOSS.
F-Droid
F-Droid is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device.

I don't know why people spend time building open source clients for not-self-hostable services. You could potentially spend hundreds of hours on something that can be shut down on a whim. Discord and spotify bots and clients, twitter or facebook clients, their APIs have been either severely restricted or shut down in the past.
Nitter is pretty good tho. Makes Twitter usable without logging in. But yeah a FOSS client for Telegram feels like a waste of keystrokes.
I don't know why Telegram is always the go-to topic for 'secure messaging', especially as a contender vs discord. When we have the option of matrix.org, which is not only encrypted, but federated.
Because Telegram offers top notch user experience, apart from excellent apps they even offer native desktop clients. I really want matrix to succeed but as of now the user experience is clearly inferior.
Try cinny. I find it less cluttered compared to element
Element is very very good.
how is it inferior? what's wrong with the user experience of Element? it's available on all major platforms with a native client + all modern browsers. has a nice ui. and loads of functions surpassing Telegram out of the gate.
