Map rendering in mobile app?

Question

Mobile development

Hello everyone, this is the first time I've come across mobile app development.
We chose Titanium ( www.appcelerator.com/ ) in the hope of building a small application for two platforms at once.
In the process, we encountered a bunch of problems, but the main one is the cards. They work very, very slowly. We use OSM and any action is accompanied by slow rendering and thoughtfulness.
Tell me, who met with similar problems? How did they decide?

Answer 1

I may be wrong, but titanium and other htm5 things are not very suitable for developing resource-intensive applications (maps are one of them). As a maximum, some kind of web client.

How did they decide?

So don't really decide.

Answer 2

Render from vector to raster on mobile? I don't think it's quite simple. Navitel killed a lot of time to get a stable engine. But he's still not perfect. In addition, you will get a very strong dependence on the speed of the GPU and the main processor. So in the mobile application - only tiles.
