- added Android 13 support
- removed ads
- improved audio processing, now using unprocessed float audio input
- some coordinate system changes

- addresses a rendering issue to make the app run on iOS 16
- improves presentation of drawing using a more uniform shape with brighter color
- features a few audio processing improvements

FrequenSee 3.0 completely developed from scratch! It no longer uses Fourier Transform (FFT), and is now instead using a custom signal processing design related to the process of human hearing, resulting in a very much improved time accuracy.

- changed sampling rate to 48 kHz, improving the support for iPhone 6s and iPhone 7, and improving the quality in general
- uses the measurement mode, minimizing the amount of system-supplied signal processing
- should now have a flat frequency response curve (influenced by microphone characteristics)

completely refined version 2.0:
- improved accuracy
- improved latency
- improved rendering on large screens
- improved connection to iOS audio
- added some supporting lines to the coordinate system
- added iPad support via universal binary
