Blocking IP addresses
Add IP addresses to prevent unwanted access.
This section covers how to use the Screening tab to:
- Block certain IP addresses from being recorded
- Set screening for OS versions
Block certain IP addresses from being recorded 
- Mobile App Testing lets you block specific IP addresses or IP ranges (e.g., to prevent recording sessions from your own team).
- Either enter an exact IP address or define an IP range using wildcards (e.g., 192.168.1.*).
- Click Add IP to add another IP address or range to block.
- For example, you can add the IP address of your company router to prevent recording sessions from your own employees.
Set screening for OS versions
- Automatically screen out respondents based on data from their user agent.
- By default, all respondents who meet the minimum requirements for a Mobile App Testing study (iOS 14 or Android 9.0 and later) are accepted.
- You can further screen out respondents based on their specific OS version.
- Either select only record from allowed OS versions to create an allowlist, or select never record from blocked OS versions to create a blocklist.
- Click Select versions to choose which OS versions should or shouldn’t be recorded, depending on your previous selection.
