iOS AdHoc OTA Distribution - Do I need to rebuild and redistribute every time I provision a device?

Question

We have an in-house iOS app that we use for quickly entering time into our time system. It's hosted on an external facing site so that our users can simply point their phone browser to the app to download and install it over the air.

The question I have is this: If I build the .ipa with the OTA Distribution profile we've set up and deploy it to the site for download, do I need to rebuild and redeploy (or at the very least, re-sign) every time I add a new device to that provisioning profile?

Note: We have a 100 device limit

Answer 1

If it truly is an Enterprise build, as in the Enterprise iOS Developer program, then you don't need to add any devices to it at all. You just need to create the provisioning profile once, and it will be valid for a year.

If it's just a normal Developer program, and you're building an AdHoc distribution - with 100 device limit, then yes.... you will need to rebuild the app every time you add a new device.
