Hi, App Image: What is the best format - jpg, tiff, giff, psd or ai? What is the maximum and minimum number of items the app can contain? Please advise. Thanks

Hi, I have a free multi-page website, my-domain.com, that offers students details of available properties. I'd like to introduce a paid service and create an app for it. Details of the service can be contained on one page on subdomain "service.my-domain.com". Would app store consider that one page as a one-page website? Would be grateful for your advice.

Hi, Completely new to all this, I have asked a couple of app developers to create a simple app, detailed below, but I have been told that App Store doesn't accept such a simple one. I'd like to know the minimum requirement by Apple, please. We only need the simplest of apps - literally an icon, when clicked, it takes the user to the home page of our website. There is a one-time download fee payable to "App Store". The app is valid for 3 months. The fee would be around 12 dollars. The app subscription is renewable. Is this acceptable? If not, how can we modify it to meet the requirements by App Store. please?
