iOS app for specific devices

Question

We are working on a kids app similar to Talking Ben app. It has lots of JPEG image sequences in it for interactive animations.

The thing is the animations are playing fine on iPad Air but they are playing slow or lagging on iPad 2. This is obviously due to the 512 MB RAM in iPad 2.

My question is can we mention in the app description something like - "Recommended devices iPad 3 or later" so that users dont download it on iPad 2 ? Or can we straight away submit app for only iPad 3 or later devices ?

Whats the legal method for this ?

In short, I want to restrict my app to be downloaded in iPad 2.

Please help guys.

Thanks

Answer 1

Not too familiar with specifically what architecture is used on the iPad 2, but this post may help you with regards to making sure the app is only compatible with certain architectures: Restricting app installations from AppStore only to users with iPhone 5/5s/5c

Answer 2

You should set bluetooth-le as a requirement in your app Required device capabilities in your info.plist.

This should prohibit your app from being installed on iPad 2 as Bluetooth-LE (bluetooth 4.0) is available only since iPad 3rd generation (see here).
