I saw this Chinese company offering a demo for their app/service which is a .ipa
file. You can simply visit a link by your iPhone via Safari and you can install
I work in a company that releases on a private store too, and it works in a very similar way. The only difference is, Apple does not check the app and it takes 1 minute to upload it, not 2 weeks.
How it works :
Users can now click it and download ;)
Click here ;-)
Note that you're not allowed to publish apps publicly like this. This is meant, for example, to distribute apps within your own company. More specifically and as an example, we had 4 apps. The store, a timesheeting app, a contact/adress book, and other specific apps that don't need to be explained. But it would be against the EULA of Apple to share any of those apps (or download links) publicly. Trying to publishing on the Apple app store would also not pass the review.
That being said, this is very practical and useful for many companies in a lot of cases, because you're free to not follow any guideline, and avoid the stressful review.
Any other questions :) ?
