I've done no marketing on the app besdies the initial quiet launch on Linkedin, Facebook and Instagram.
But every now and then, I like to check the app to see how it's doing. And to my surprise, it's achieved over 1,000 app installs in the 2 months that it has been out, with no marketing.
I am very grateful for this, and don't know how it has happened.
However the app still has plenty of room for improvement (which I doubt that I'd do). Because the daily active users (which is the metric that matters most) is about 1%.
