Mattermost

I like the idea, and on web on PC it works well. On mobile there are many issues; it is slow to start, often presented with a white screen you cannot get off of, scrolling often doesn't work. There are also improvements to the app I would like: the ability to read messages offline, the ability to pull the sidebar across.

Switched our team to mattermost instance because I believe open source is important. The Android app is lacking though. Startup is slow and does not feel polished.

Promising. Did not work with self-signed SSL. Laggy (probably due to app being a wrapper fit the web site). Would be nice to have audio and video chat in the future.

It lags when I type, and the keyboard closes whenever I press the send button. You'd do better to use it directly in the browser. Please, a native app.

Useless. Also shows 'download native app' in sidebar. Fail.

This is not a real Android app, it is just a browser (slower than Chrome) that points to the mattermost server. Completely useless.

When switching from Slack to Mattermost, I expected a fully functional Android app, as the Desktop functionality seemed pretty amazing. As the Android app (and probably the iOS one, too) are basically browser wrappers, you're better off using Mattermost in your mobile browser directly.

Kinda sluggish, and needs much data...but gets the job done!

How do I send a message on my tablet? There's no send icon and enter gives a new line...!

Red circle in the middle of the screen that won't go away, very slow, won't work with http servers, HTTPS only.

You've managed to crash more of android with an app than I thought was technically possible.

Works okay as a browser wrapper. Is still a bit slow/sluggish. And if you accidentally close it using the back key it will log you out.

Works well enough in my opinion for team messaging, but as others note it is simply a wrapper for the web interface and thus it really is just a reference implementation. I would really like to see someone work on a native app to replace it. It's not so unresponsive as to be impractical, but just slow enough to be occasionally annoying (on a Nexus 5). One specific beef I have is with the emoji. The interface for inserting emoji is the same type-colon-to-see-context-menu approach, which is extremely unwieldy on a smartphone where depending on the input method used, the colon is a lower priority character and is often buried several clicks away. Emoji on smartphones need to be much more accessible. The whole point of emoji is to alleviate text entry through the cumbersome smartphone interface, not exacerbate it. So whoever implements a native Mattermost app, I hope they just copy the standard one-click emoji menu used by every other chat client on the planet ;) This is true for all Mattermost clients though. The system still pretty much requires you to know the text name of an emoji to find it, which is a weakness with the program. Certainly not game breaking, but an annoyance.

Very bad UI. Unfriendly and complicated to switch between channels. Back button logs you out...

After the upgrade I only get a white screen.

Not able to connect to server through app

Probably because is just a webview

It so sloow

Title says it all.

Works, but only just.

Extremely slow

Like another's comment, it works but it's clunky. For one thing, the red loading circle ⭕ doesn't completely go away after loading the app or a new view. Switching views is not smooth either.

Worst android messaging application I have used. No scrollback, keyboard closes on every message send. Back button doesn't close sidebars, no slide to close sidebars. Awful. I only use it because the desktop experience is worth having. Mobile is _awful_.

It works but not well

Unresponsive, disconnects all the time and it doesn't notify of new messages correctly! This entire service is a joke! Slack is expensive, but it works! You get what you pay for.

This is literally just a browser that opens the site you tell it to. It's compete crap.

For a web wrapper it works rather well. If it comes up with a white page it's enough to put it in background and bring it back. Push notifications work reliably. (Make sure to configure your device not to kill the app in background!)

I love Mattermost, but this app needs to become more responsive. It works without bugs so far, so it's not that big of a problem.

YANDEX TRANSLATOR: There is no button to send a message to the tablet When you click on enter, there is a transition to a new line

Not native, can't be used as a target for sharing things, not responsive, has weird buggy behaviour. All in all a bad experience.

Unresponsive. 30 sec to boot. 10 sec to show the keyboard when typing the text entry. Apart of that, the application is complete. But this is soo wrong. Very poor UX.

Some bugs, but nice app.

Need a native app before can be a serious Slack competitor

very slow, no landcscape view, no option for in-app notification, hard to change team, colored noti-small-icon(must be black&white). rebuild your app immediately.

Not a native Android app, just a view of the web page. Slow, clunky and unreliable. A native app would be well received.

It's great for reading messages but I cannot respond on the app anymore. It types so slow, it's not worth it. It's so delayed.

Bad experience. Not Native.

Just a webapp wrapper instead of a native experience. This makes it very painful to use properly, while mattermost is quite a vital channel of communication within the company. Implementing simple touch feedback on some buttons could improve the mobile experience already significantly.

It takes at least 10 seconds to respond to any input and behaves in utterly unpredictable and confusing manners. Why anyone thought this was an acceptable piece of software for release is beyond me.

I tried to implement mattermost to replace slack and was pretty Impressed by the performance and features on the desktop. Sadly, most of our companies interaction is on the phone and this app is really clunky and unresponsive most likely because it is an html wrapper. This really killed adoption as it is frustrating for millennials to use as it cannot compete with the speed of ANY other messaging application it is competing for time with. DO NOT WASTE YOUR TIME INSTALLING THE SERVER!!!
