# The maximum number of apps for free development profiles has been reached.

> A free Apple Account allows 3 apps signed with Xcode on an iPhone. Delete one and install Mobster's helper again.

You see this: `xcodebuild` prints this as the recovery suggestion for `Unable to Install "WebDriverAgentRunner-Runner"`. Mobster shows `Delete an app you installed with Xcode from your iPhone. A free Apple Account allows 3`.

## Why it happens

iOS caps apps signed by a free Apple Account at 3 on the phone. Waiting never frees a slot; deleting an app does.

## Fix

1. On the iPhone, delete an app you installed with Xcode: touch and hold its icon, then **Remove App › Delete App**.
2. Install Mobster's helper again from Mobster for Mac (**Devices**), or run the guided setup's `setup /build`.

## Check it worked

The install finishes and `mobster doctor` prints `✓ WebDriverAgent`. A paid developer team has no such cap.

Checked 26 Oct 2026 against Mobster 0.4.0. Back to [Troubleshooting](https://docs.mobster.dev/troubleshooting.md#iphone).
