What’s new

- Much more accurate EMF readings: added compass-style calibration to remove your phone's own magnetic interference, so simply rotating the phone no longer causes false spikes
- New "Measurement Mode" setting: choose between Accurate (stable, calibrated) and Sensitive (bigger, more dramatic numbers)
- Redesigned Settings screen
- Various improvements and bug fixes
