I have been working on a minimalist and calm work/task tracking app called Dodolr (doo-doo-lr) which supports tasks (dodos), notes and follow-up since last few months. I deliberately didn't build notification or reminders and leave it to the user to be fully accountable for completing their work (moving tasks to terminal stages). I'm building it for 3 local customers. Would be happy to give Early Access to any solo founder and power user who prefer non intrusive tools to keep a tab at their work. The app works well form small 1-3 person team very well.
The landing page is at: https://www.dodolr.com
Please submit the Early Access form if you want an access. Happy to answer questions here as well.
