User #2 Feedback (Roommate) = Ease of use is a plus. Straight-forward design with error message for invalid inputs and output for valid inputs. Color combinations can be improved.
User #3 Feedback (Friend) = Convenient to use with only one input field; no extra directions necessary. Information is organized in a easily-readable way. Larger font sizes in some elements will be a plus.
