This app does let you browse through a lot of fonts. Unfortunately, the UI does essentially nothing to answer the question "How should I approach the task of browsing through a library of thousands of fonts?"

The app is designed around size-mortised grids, much like many disk space auditing apps on PCs, with "size" apparently being defined as "number of fonts". Unfortunately, that means the UI presentation has little to do with any information you might actually be interested in as a font consumer (e.g., what fonts are similar to this one?) The basic premise of the app is ill-conceived.
