A simple font tool for developers working with SwiftUI. If you're like me, you are always forgetting the hierarchy of font sizes: Which one's bigger again, callout or footnote? So I built this free visualizer tool for iPhone that shows them all in a neat list, and has customization options for font design, weight, width, and dynamic font sizes. Also available on macOS with a Menu Bar Extra app for fast access when you're using Xcode.

Verdict
The clearest difference is in-app purchases: SixD at none against Fonty McFontface's 3. SixD also leads on rating (4.8 vs 4.5) and ratings volume (29 vs 8). Fonty McFontface's advantage is review sentiment (100% vs 90%) and iOS requirement (17.0 vs 26.0). On price, update cadence, ads and device support there is nothing between them.
