One takeaway is just do it. Release your fking app, tell people about it, and listen to their feedback. Iterate and repeat.

From April to May to June, I improved the app and created a follow-up post in reddit
that post brought me the first 11 paying users and $110 in sales
fast forward to today, the little time tracking app now makes a total of more than $3k in sales, and I can see it growing.

In April, I stumbled upon a Reddit post asking about a simple time tracking app for Mac. The OP couldn’t find what he was looking for.

I spent 7 days building the app, reached out to the OP, and asked him to try it out. The next day, I got my first $15 internet dollars.
