I want send my app for testing to multiple users. I don’t want to go for Apple approval process.
I read about Enterprise program. But is there any limit for number of users?
Is there any alternate option for this?
2,000 testers? I would suspect that you don't have 2,000 testers but that you want to distribute an app outside the app store.
The Enterprise program allows unlimited number of customers within your company. You pay $299 to join the program and you sign a legally binding contract that you do NOT make anything available to anyone who is not an employee of your company. If Walmart writes an app that Walmart is using internally, no problem sending it to 2,000 Walmart employees. Do you write an app for a company with 2,000 employees?
