Mobile App Performance/Profiling

I am having a few problems with the iPhone mobile app. First I get network error often and consistently. The app remains offline for prolong periods of time. I notice that while it is offline my app is frozen since I rely on a lot of database queries. Here is the message that I see:

Also the mobile app runs very slow compared to the simulated app in the IDE. Often times I will take a minute or more for the app to respond to a click event on the mobile iPhone version while in the IDE it responds immediately.

Finally, without profiling tools it is difficult to near impossible to diagnose where the bottlenecks are in the mobile app.

As it stands now. I am unable to recommend the mobile app solution that I am building for a client because of performance issues and the inability to diagnose where those performance bottlenecks are so that I can mitigate them.

Upon further trial and error it appears the performance bottleneck I am experiencing may be tied to the 'auto-grow with content' attribute on the user input field. When set to true I notice the performance issue. When this property is set to false it appears the performance issue goes away. I will continue to test.

That's a very interesting observation, @neilbalthaser. I will check this out on my end, as well. :+1:

I did some preliminary research in a very bare-bones mobile app and was not able to reproduce either of the issues that you've outlined here, @neilbalthaser. It's certainly possible that they are contextual, though, so it might helpful to get a JSON export of your app that includes hard coded query data.

In the meantime, I will look into the feasibility of expanding the mobile app's debugging capabilities!
