With the given instruction, record a 30-second video instruction on how to use the app. The app is a well-known app available in Android and Apple play store with 1M+ downloads. For this you will need to install, quickly configure simple settings and record a video actually using it while speaking, We need a video with actual female fingers using the app and a female voice saying the instructions, therefore we need not just screen recording, but you need to have other camera or phone to make a recording of this video using fingers. The audience is young adults, so we would like to consider candidates with young voices.
