## What it is
An iOS library that acts as a framerate meter, playing a Geiger-counter-style click whenever the app drops a frame during animation. It also displays counts of frames dropped and drawn per second to help developers detect performance hitches.

## Use cases
- detect dropped frames in my iOS app animations
- hear an alert when my app drops below 60 fps
- find CPU spikes causing table view scroll jank
- measure animation smoothness during development
- debug main thread stalls affecting framerate
- tell the difference between 55 and 60 fps in my app

## When to choose
- you're developing an iOS app and want quick audible feedback on dropped frames
- you want a lightweight in-app framerate meter without external instruments
- you're hunting main-thread CPU hitches like layout or cell configuration stalls

## When to avoid
- you need to measure GPU-caused frame drops, which this tool cannot detect
- you're profiling on the iOS Simulator, which doesn't reflect device performance
- you need a production monitoring solution rather than a development-time tool
