As I wrote to some of you earlier, I used multiplatform Marmalade SDK for apps development.
Because of that I had ability to create mobile apps for various platforms in MS Windows environment.
That was a great for me at first time. But now disadvantages outweighs advantages.
I can't infinitely wait so annoying issues fixes like non-working 3G, etc.
So I deside to switch development environment to native iOS SDK.
The first move in that direction is Renko charts app family
New v.2 version of Chebyshev's Trend will coming soon!
