Validately Recorder is a free screen recording tool for Android devices. However, it is important to note that this app is not a general-purpose screen recording tool. It is specifically designed for users who are scheduled for research or testing sessions with someone using Validately.

The app uses the built-in hardware on your Android device to record on-screen activity and audio. It is important to connect to a reliable Wi-Fi signal or hotspot while using this app as it can be very resource-intensive. The developers also recommend plugging into a power source or ensuring that your battery is 50% or higher to ensure that the app functions smoothly.
