Inviting testers
Last updated 16 August 2026
On your side, inviting a tester is one email address typed into a project’s dashboard. What happens after that depends on whether they accept.
Adding a tester
Open the project and add their email
From the project’s dashboard page, type the address into the tester list. Free projects hold up to 10 testers each; Pro raises that to 500, and Studio is unlimited.
They get an invite email
The invite is created as pending — whether or not that address already has an App Dropper account.
They accept
Only then do they become a member of the project: able to see it, get notified about new builds, and install them. Declining or ignoring the invite leaves the project untouched.
Nobody is added silently
There’s no way to drop someone into a project without their say-so. Nobody is ever auto-joined on your behalf, even if they already have an account.
How testers hear about a new build
Two channels fire independently the moment a new version is uploaded:
- Email. Every tester on the project gets one, with a link straight to the install page.
- Push notification. Testers using the App Dropper mobile app also get an instant push, and can install any build — the latest or an older one — with a single tap. No link to dig up.
Managing the list
The tester list shows who’s been invited and who’s accepted, and you can remove someone’s access at any time. Testers can also remove themselves.
Building for iOS with an ad-hoc profile?
An invite alone isn’t enough — the tester’s device has to be in the provisioning profile or the install will fail. See iOS UDIDs for ad-hoc builds.
