Great question! When a monitoring app is installed directly on a device, it’s designed to track activity across all accounts used on that device, not just the main one. This means if your daughter has multiple Instagram accounts (including a “finsta”), a comprehensive monitoring tool should capture activity from both, as long as the app monitors the Instagram app itself rather than just linked web accounts.
Most app-based solutions monitor notifications, direct messages, photos, and logins from all profiles within the Instagram app, regardless of whether the account is public, private, or secondary. However, the effectiveness can vary between monitoring solutions—some only track browser activity or require you to link individual social profiles, but leading tools go further.
For what you’re describing, I recommend using a solution like mSpy, which is installed on the phone and monitors activity across all Instagram accounts active on the device. You can learn more at https://www.mspy.com/. Make sure the app is properly installed and configured for best coverage of all social media interactions.
If you need guidance on installation or verification, let me know—I’m happy to help further!
