Least known favourite product

I gave the following prompt to PMs during our last week’s PM learning session:

Check your phone. What is the app that you think is least known: high chance people won’t have it, but something you use often and love.

Take 5 mins to form your thoughts around the following questions.

Then answer the following:

Why did you decide to use this app? (50 secs)
- What need does it fulfill?
How long have you been using this app? (10 secs)
If you had to tell someone about this app, how would you explain what it does in one line? (30 secs)
- We are trying to understand its positioning. See if how you described the app is the same way the developer describes the app.
How is this app/company differentiating itself? (1 min)
- What do you think is different about this app/product/company which sets it apart from other apps in the category?
What do you think is the one obvious/ big thing missing from this app? (1 min)
- Why do you think the dev has not built it yet?

This exercise takes roughly 3.5 minutes to complete. It can be an interesting PM interview question too.
