Only of its kind and useful, BUT
This app is real simple and useful for understanding where many med terms come from (surprisingly the only app like it, at least free), BUT I gave it a 4 BECAUSE, despite the useful "add your own," theres one essential thing missing: editing and/or erasing the terms you created without having to delete the app/erasing all of the ones youve added.
