It needs some polish, but mechanically and aesthetically, but it functions. The most concerning bug for us is that the iPad app will send notifications about new messages but not show those messages in various channels and threads until we shut down the app and open it again. There are several minor hiccups like that, but not enough to scare us away from a secure, convenient messaging platform as an alternative to Discord. ### 1/5 — Notifications broken now *2026-06-16, version 4.73.1* Recent update means zero notifications. all settings are correct for my phone, but I no longer get any notifications at all. No banner, no sound, no badge icon, no lock screen. Nothin. uninstall and reinstall doesn’t work. even installed on a different device and notifications still don’t work. ### 5/5 — Good *2026-06-16, version 4.73.1* Good App ### 3/5 — Buggy *2026-06-14, version 4.73.1* Issues with sending messages and having them not show up, issues with getting notifications and then the messages don’t show up. ### 5/5 — Amazing *2026-06-13, version 4.73.1* Amazing ### 5/5 — Rocket.chat has been great *2026-06-04, version 4.73.0* We use their app in our internal portal for direct messaging. It has helped our company collaborate, share best practices, help one another, and create a closer online community! I would highly recommend. We have used it for years now. ### 5/5 — One of my favorite way to communicate *2026-05-24, version 4.72.0* New to the app and so far it’s good. ## Frequently asked questions about Rocket.Chat ### What is Rocket.Chat?
