Good app... A little more for 5 stars

Three suggestions
1. The appearance is a little too plain.
2. The ability to log data, maybe plot it, would be terrific.
3. No way to calibrate the instrument. I am sitting next to a NWS barometer that reads 29.929"and the pad reads 29.897" It would be great to have a way to recalibrate the pad.
