Typography Lab
Free · Designed for iPad. Not verified for macOS.
Design your app’s typography in real time.
This app is a font playground for app developers.
Try different fonts, adjust font size, line spacing, and kerning with simple gestures, and see exactly how your text looks on a real device — including Dark Mode.
Instead of guessing values or going back and forth with design tools, you can fine-tune everything directly on screen and export ready-to-use SwiftUI code.
What you can do
• Browse and preview system and custom fonts
• Adjust font size, line spacing, and kerning by tapping and dragging
• See changes instantly in Light and Dark Mode
• Copy or share SwiftUI code for your typography
• Reset and compare different settings easily
Whether you’re designing a reading app, a note app, or any text-heavy UI, this tool helps you find the perfect typography faster and with more confidence.
Design it. Test it. Ship it.
