As of 2018, there are now two available versions of the mobile app. The classic is going to be eventually discontinued, but they haven’t said exactly when as it still has a number of features that the newer app does not have.
On the other hand, Samsung brand smart televisions and appliances now work only with the newer 2018 app. You will also need the newer app to set up some of the newer smartthings model hubs. (You can also use both apps if you want to.)
There are quite a few other differences, so if you ask a question in the forum, people will typically immediately ask you which version of the app you are using.
It easy to tell the difference: they have different logos.
Note that the name of the 2018 app has changed multiple times since it was first released. As of July 2019 it has changed again, and now it’s just called “SmartThings.“ But with the same picture logo as shown above.
Unfortunately, a lot of the documentation, including the app descriptions, hasn’t all been updated and there is official documentation which still calls the classic app “our new app.“
That means there are forum posts from 2015 through 2017 referring to “the new app“ which are really talking about the one that is now called “the classic app.“ It can get very confusing
What to call the two apps in forum posts?
We’ve tried coming up with abbreviations and nicknames and stuff like that since “smartthings (Samsung connect)“ was released in April 2018, but none of them have stuck.
So one year on, when “new“ isn’t quite so new, we’re going to try something else.
The original version of the app had a lot of “hello, home“ verbiage and came out when the V1 hub was released. So we’re going to call that the V1 app.
Then when the V2 hub came out in the fall of 2015, A new version of the app was released. It introduced smart home monitor, smart lighting, rooms, and routines. At the time that it was released it was called the new app. Later on it was called the classic app. It went through a lot of versions over the four years since it was first released, and in particular the icons and their names at the bottom of the screen changed multiple times, but you can see they’re all related.
in this forum, just for shorthand and to futureproof posts, let’s call it the V2 app.
In 2018, the V3 hub was released, and a new app came out from a new UI development team. Originally they tried just calling it “SmartThings” and re-naming the V2 app to “SmartThings classic.” But after about six weeks they changed the name in the App Store of the newer app to be “SmartThings (Samsung Connect).” So you will see support referring to it both of these ways.
In the forum we tried using the abbreviation STSC, but it didn’t really catch on. So let’s just call this one the V3 app. It came out in 2018 when the V3 hub came out. It looks very different from the 2015 app, and includes its own if/then rules engine. And a picture of a plant.
2019: for now, you can use V2, V3, or both apps if you like
You will have to use the V3 app to install the V3 hub, but after that you can use the V2 app if you want to. Or both of them. The V1 app is no longer available for download.
They told us that the V2 app will be going away eventually, but they just haven’t said when.
For more information on the differences between the V2 and the V3 apps, see the following:
Also, note that neither of these is a “smartapp.” SmartApp is a term that applies to code that runs on the SmartThings platform. Not the mobile app that runs on your phone.
So if you are searching the forums and you see something that refers to “the new app,” check the date. If the post went up between 2015 and early 2018, it’s probably referring to the V2 app. Not the V3 app, since that was not released until 2018.
Got a better idea for what to call these?
If you have a better idea for what the forum should call the two currently available apps (And it’s family friendly ), there’s a current ongoing discussion.
