A useful way to evaluate it

  1. Create a person using fictional details, such as “Sam likes pottery and has an interview on Friday.”
  2. Review the proposed card details. Check that editable suggestions stay separate from saved facts.
  3. Save a dated event and confirm the notification settings. Check the note again before contacting the person.
  4. Open a check-in draft. Edit it and confirm that the app has not sent a message for you.
  5. Try the same job with your current notes and calendar setup. Describe where Cynnes helps and where it adds unnecessary work.
