Ape Apps

I just started using EZ Register, free version so far, and put it on my android phone, my wife's iphone, and our ipad. On everything but my phone I can see a running balance after each transaction. On the iphone that shows after rotating the phone to landscape mode. On my android the app doesn't yet seem to be able to operate in landscape mode. Is running balance or screen rotation a premium feature for android on this app? Am I missing something? Could you add a running balance feature to the android version? Otherwise, this app seems awesome, thank you for building and developing it!
