v1.0.2

Bug fixes and code improvements.

What's Changed

• Properly disable pitch detection when app is backgrounded and re-enable when foregrounded.
• Throttle pitch UI updates to ~60fps.
• Code improvements for readability: avoid magic numbers, add code comments, etc.

Caution

This release is broken! There's a race condition revealed by the backgrounding/foregrounding fix. v1.0.3 is out to address this.
