Also OT: I built something very similar, but with text messages and asking for a positive thing that happened during the day rather than a journal entry (forcing myself to look for positive things in a day helped snap me out of a spiral toward depression in the early days of lockdowns). I spent a weekend getting it to the point where it was good enough to share with friends and family, and about a dozen of them signed up. My mom and I are the only ones who still use it. I guess I have two thoughts: 1) simple, habit-based products aren't nearly as sticky as I thought without some kind of social validation component. 2) dogfooding your projects with your personal network is a great way to see if they're actually sticky and just to learn more about the market in general - I recommend it.
