I encourage you to checkout https://simplex.chat as well

TSB has a group chat you can join. Simplex doesn’t even have usernames, frictionless onboarding experience. Has cool features like incognito mode which gives you a new nym for every group you join when it’s turned on, and allows you to run your own relay-like server. They’re rapidly releasing new features as well.
