An IOS app for groceries, good idea or bad?

[pitermike]

Hi guys,

I have a business of selling online groceries. I have started it on a smaller scale at the moment with only an online store with a website. Since my business has started generating a little revenue, I am planning to increase the size of my venture by introducing my mobile application. For the start, I just want to go for an iOS application, and then move later on Android. Are there any mobile application company providing custom iOS app development services in USA?

Please suggest me some names to go through. I want to get it done as soon as possible.

Thank you.
