logmyhours.com - I'm happy with it so far though, it's something I've built for myself (I log all my hours working on it) and 100% on my own and has been a great learning experience. But it is getting harder and harder to work after work.

I love that I get to chat with customers and see what really are their pain points (something devs rarely ever get to do).

If I can double the MRR and relocate outside of Vancouver, I can most likely go full-time.

Hope you are able to do that. I guess at your point it's getting a few more clients via different scrappy ways (cold outreach, etc), and keep using their feedback/behavior to improve the product.
