Pretty much every new app has the following problem: lots of people sign up but don’t stick around.
I frequently get asked what are benchmarks for retention after one day or one week. My answer tends to be the same for products in the early days:
Ignore the benchmarks. Find the patterns in the stories of people who do get your product. Figure out what converted them and got them so excited to keep using your product every day or every week. In the early days, your main focus should be to attract and create more and more of those “core users” who deeply use your product. Over time you can try to increase averages, but first, you just need a core and strong base.
Most people look too much at the “big data” and try to draw conclusions. In the early days of a product you have to talk to people. You need anecdotes much more than data. You could say The plural of anecdote is data.
