I built a platform for turning journaling into a habit, looking for feedback

https://www.simplejournal.online/

I've found that it's easier to create a routine or a habit out of anything if you keep a log of what you did and when. Maybe write a little bit about the experience, save a picture.

Simple Journal was born from that idea. Keep a journal, every day. Want to do something more often? Keeping track of it is the first step.

The main concept behind Simple Journal is keeping a streak. Log something every day. Doesn't matter what, just keep at it.
Want to reinforce a habit? Like painting for example? Save it as an activity on the platform, and start logging.
Then review your progress over time in charts and calendars.

I've been using, testing with a small group and refining the platform for the past three months or so. Any feedback on the concept or the execution is welcome. Also looking for any launch tips & tricks. I've already published the platform on Hacker News and Product Hunt, now looking for next steps.

Thanks!
