Urgent Help with low fps on iphone 6 plus

Hi,
Apple just published my game, but as i tested it with my sister’s iphone 6 plus, the FPS is awfull… mabye 15 or less…

It’s an iphone 6 plus ios 8.3.

I also tested it with my brother’s 6s (ios 9), and it has the same low FPS :frowning:

The game works perfectly on Android devices, and it’s a pixelated 2d with graphic assets that are 400kb all together! with efficient and simple code.

so my question is, Why is the FPS is that bad on iPhones?

Thanks,
Tal Rumer.

It’s really urgend guys, id love to get some help :slight_smile:
