Downloading and Installing .IPA files for installed apps in non gailbreak devices (developing an appstore)

Question

I am going to develop an app-store app. The clients should be able to download the IPA files and install it directly to their device and replace it with old applications. Surely most of the device are non-gailbreak so surely I should support them too.

I had see some apps like TestFlight that do it for Ad-Hoc apps. They install some certificate and then install the app actually I do not know what they actually do and also how can I do it for apps that should be install in all devices.

Do some body know any solution?

Answer 1

You can not do it via ad hoc distribution. You can do it for around 100 devices only. If you want to install the in all devices either you will have to go to Apple Store or you will have to purchase Enterprise distribution account (which is to server the application with in the organisation).

The application like Test flight also allows to install the application on those devices whose UUIDs are registered in the uploaded provisional profile. It is not doing any magic. It just provides a way to install the binary over the air.
