Question about Developer Certificate

I have a developer certificate; I want to compile my project with a release version. How many device can I 开发者_运维问答use to try my app?

You can run your app in maximum of 100 devices provided that those devices UUID's are added to the developer provisioning profile. Check out this Adding devices to team provisioning profile, SO post for reference.

You can have as many devices added to a certificate and as many simulators(computers) using the same certificate to install apps on multiple devices.
