First off, this looks awesome. I've heard people complain many times about how they just want a personal CRM for non-business purposes. On the one hand I love the idea because having such a specific use case allows you to make a very simple UI that does exactly what the user needs. On the other hand, I never personally chose to go after it because getting individual consumers to pay for stuff seems hard.
So I wish you the best of luck, and I hope you stick with it. The "Why Monica?" section of your website sounds like it was written specifically for me, and I'm definitely going to try it out because of that copy.
My main piece of advice: be skeptical of most product suggestions. As someone who has been building a simple CRM for the past ~8 years, I can tell you that everyone wants something different, and if you react to every suggestion you get, your product will end up losing the awesome focus it has right now. That doesn't mean you should ignore feedback, it just means you should make sure the feedback is coming from your actual target audience and not some random person who's looking for Monica to be something it isn't. I fell for that too many times in the early days.
