Element

This is my most used app on my phone. It does comes with a little extensive setup, because you need to have your own Matrix server, but thanks to the amazing Matrix Ansible Project, which is one of those rare docker/ansible projects that actually work and are very robustly set-up, deploying a server took me like an hour max, incuding bridge setup and getting hosting (for around 8$ a month on Hetzner).

I replaced Messenger, Discord, WhatsApp and Telegram apps with this, by setting up bridges in Matrix. The setup was relatively simple, the ansible is well documented and I mostly had to just add lile two config lines into the ansible. So far I haven't had much issues and I've been using it for the past few years.

There might be better clients than Element, haven't really looked into it. It's not frictionless and it took some getting used to, but not having a ton of spyware appson my phone is worth it.
