Functionality

  • Displays deviations between -60 and 60 cents.
  • Supports scientific pitch notation and Solfège.

Tests

Run ./gradlew test to run all unit tests. In addition, there are UI tests based on image comparisons which can be run using ./gradlew connectedCheck. The reference images are generated using a Nexus 5X emulator (resolution: 1080 x 1920, 420 dpi) with API level 26.
