Thank you! Really glad it resonates with you - the AuDHD community was actually one of the main groups I had in mind while building this. The "likelihood of plans falling through" thing is so real.
The busy/available toggle is a great idea. I can see how battery level ≠ availability (you might be recharged but already committed, or drained but still down for the right person). Adding that to the roadmap! Let me know how it works for you if you end up using it.
