I just started working with dhtmlx touch, and I waned to say you are the geniuses of visual presentation, speed and easibility.
Like the suite, Touch is an amazing piece of work.
Oh, Thank you so much for your kind words about our products ! 
In my mobile app, I need to integrate a ID Tech credit card reader which plugs into the headphone jack of an iPad.
I spent sometime researching how I might do this. I looked at phoneGap, moSync, Titanium mobile and a few others.
Long story short, I decided to use ios xCode and create a webView which runs my dhtmlx web app. So far the app runs very nice inside of the ios webView container. I’ve learned how to make javascript communicate to IOS and IOS to javascript. Really pretty easy to do.
During the process, I spent sometime learning how to build a native ios app with controls and forms. What’s crazy is Mac xCode has no good way to display a grid with headers, columns and sorting.
So I looked for a tool which might help, and came across a $395 ios/objective C framework which creates grids. I installed their sample iPad app to test. The grids look ok. The performance is horrible–very slow.
And these are native ios grids. All this hoopla about native code running faster than html5 is not always accurate. My tests showed that dhmltx’s grids are way faster. Charts are in a similar category.
Furthermore, once a native app is built, that’s it. You want to change it, forget doing it on a dime. Running the mobile content inside of webView is a great way to serve the mobile app which has dynamic content while at the same time communicate to native ios functions from javascript.
