iPhone app too small for iPad

Good morning,

I have a problem regarding the iPhone app I uploaded to the App Store. I set the compatibility of my app to Universal so it works on iPads. I tested the app on my iPad and the text for all of the pages on the app were too small. I tested the app on the Xcode's iPad simulators and the app works fine there. I was wondering if this issue affects other iPads or it's just a glitch. The app is called Vtronix. Please let me know what I have to do to fix this problem.


Regards,

Karran
