Maximum Testers in TestFlight

Question

What is the maximum number of testers that i can add to TestFlight Account? Is there any limitation? I have created and built iPhone application and uploaded to TestFlight. Then I added a Tester. He could download and install that. Since I am using Free account of Test flight, I would like to know its limitations.

Answer 1

NOTE: This answer applies to the old testflightapp.com services. The rules have changes now that Apple owns TestFlight.

You are limited, by Apple, to only having 100 Ad Hoc devices. This is a per year limit. If you add a device, and then remove it, it does not let you add another device.

So, even if TestFlight let you add more than 100 devices, you still could not install the Ad Hoc provisioned app on them.

Answer 2

As of 13.11.2015, there was an update from Apple:

To make your TestFlight experience even better, we’ve made some significant changes. You can now invite up to 2000 external testers and up to 25 internal testers per app. You can also test up to 100 apps at the same time for up to 60 days, and submit up to 6 updates per day to your external testers.

Answer 3

I believe the limitation depends on the iOS program your are enrolled in.

The limit of 100 devices is for the iOS Developer program.

There is no limit if you are enrolled in the iOS Developer Enterprise program and are distributing your Enterprise signed app.
