Hope you are all having fun with the design process.
My guess is that in a week or two, you may want to perform usability testing. I can vouch for this tool called Lookback ( https://lookback.io ), which I used about 6 months ago for my task analysis.
The users need to install this app, following which their screen recording and feed from the front camera are recorded simultaneously. Multiple designers/researchers can view this activity live, and the recordings are available as well.
If you are aware of any other tools that may help people here, feel free to mention them here.
