Should I be support 4 / 4S resolutions for iOS Apps?

over 5 years ago from , UX Lead

We make apps for iOS and Android devices in a bunch.

I am stumped over the issue of supporting resolutions for iPhone 4 / 4s. It is difficult to say "NO" to client for supporting these old resolutions that adds additional development time.

The MixPanel research shows constant decline on the usage of these devices - although collectively still representing 20% market share.

Somebody - please guide me what to do?
