What’s the best way to help control my grandmother’s iPad remotely?

TeamViewer is one of the more straightforward cross-platform options, and it has a free personal-use tier. You would install it on both devices, have your grandmother read you the connection code, and then have her approve the access request on the iPad. Remote control without consent would obviously be illegal, but these support apps are designed around the person at the device explicitly allowing the connection. The biggest challenge may be teaching her which buttons to press, so setting everything up during your next visit would help.

If her iPad is running iPadOS 18 or later, FaceTime can support screen sharing and, with her approval, remote control during a call. That may be easier than asking her to launch a separate support app and enter a code. You’d need compatible software on the iPad, and she still has to accept the control request.

Be aware that TeamViewer isn’t universally loved by IT users. People have reported security incidents, false commercial-use warnings, inconvenient licensing, and connection problems when the two installations are on different versions. Alternatives worth comparing include AnyDesk, RustDesk, Splashtop, or Chrome Remote Desktop, although iPadOS can limit how much control these apps actually provide.

For many tablet problems, a video call with screen sharing may be enough even if full control isn’t available. Google Meet or a similar calling app can let you see what she is doing and talk her through the fix. Some sensitive apps, especially banking apps, deliberately block screen sharing, so those may need to be handled through the service’s website or with someone physically present.
