I am looking for free website/desktop app for making flowchart/logo/diagram for research work especially health informatics based research. Will you please suggest?
On MacOS, Omnigraffle is and has been for years my go to app for anything diagramming, flowcharting. All of my diagrams for my music technology textbook have been done with Omnigraffle. I also use many icons from a subscription to Flaticon. Sorry not free but worth the modest cost of a subscription. DBW
