I think many folks may not realize that the difference between a web-app and “App-app”, these days, is much, much less than in the past. The first time you use our web-app, it is fully cached on your viewing device, very similarly to a downloaded app. The web-app uses advanced Javascript code, libraries, and graphic resources, just as an “App” would use Java bytecode. Many “App-apps” actually just run a “web-view” region - i.e., they use the browser libraries to show a web page; it is just hidden from the user! Finally, ActionTiles does not assemble and render HTML on back-end servers! All computation, layout, data binding, and presentation is done on your phone or tablet just like an App; including presenting every data element (Tile), which is connected to your dynamically updating Thing data as it is pushed from SmartThings.
I’m not disputing that you experienced extremely unacceptable performance delays while testing ActionTiles; but I’m saying that such delays are absolutely not characteristic of our product.
I don’t know why such a problem occurred for you, but as a certified "Works With SmartThings"™ product, we are committed to providing customer support to investigate and resolve such problems, including partnering with SmartThing back-end engineers when required.
So all I am asking of you is to considering spending a bit of diagnostic effort with Support@ActionTiles.com
and we will resolve the anomaly that you ran into. Indeed, if you have happen to have run into an as yet undiscovered bug or a compatibility scenario, then I am also concerned that other customers may be experiencing it and just not telling us. (Nobody has reported this though, including our thorough Beta participants.).
By helping us help you, you will be making a valuable contribution to the SmartThings Community (yes; the exact same community that is offering assistance and various helpful options and explanations to your inquiry and to hundreds of other folks in this Community Forum).
ActionTiles doesn’t resolve all the limitations of the SmartThings mobile app. We are a supplemental companion app that is designed to fill certain gaps very well, such as, “Guest Access”, the title of this Topic.
