Rabona

Rabona is your personal typography lab — a fast, focused workspace for putting any typeface through its paces before it ever ships into a design.

Great type is felt, not just seen. Rabona gives you the controls to feel it: dial in the exact size, nudge letter spacing point by point, and open up or tighten line height until the rhythm sits right. Watch your sample text respond live, so you can judge how a face actually behaves instead of guessing from a specimen sheet.

Readability is where good typography earns its keep. Test contrast and colour combinations against real backgrounds, drop in custom hex values, and flip into dark mode to see how your choices hold up after sundown. When you want to know whether text survives the real world, simulate it — apply blur to mimic tired eyes or small screens, switch to grayscale to check that your hierarchy still reads without colour doing the heavy lifting.

Found a setup that sings? Save it as a typography preset and pull it back up any time. Build a small library of the combinations you trust and stop rebuilding the same test from scratch.

WHAT YOU CAN DO
• Preview any typeface with adjustable size, letter spacing and line height
• Check readability, contrast and colour pairings at a glance
• Enter precise custom hex colours for text and background
• Simulate real conditions with blur and grayscale filters
• Toggle a comfortable dark mode for low-light work
• Save typography presets and reuse them across projects

Rabona is built for designers, developers and unapologetic type nerds who care about the details most people never notice — the ones that make reading effortless.

And it respects your workflow as much as your eye. Everything runs 100% offline. There is no account to create, no ads interrupting your focus, no tracking following you around, and no unnecessary permissions demanded up front. Open the app and get straight to work — your presets and settings stay on your device, private and instantly available whether you are online or not.

Stop squinting at cramped specimen images and start testing type the way it deserves to be tested. Rabona turns typography from guesswork into a craft you can control, one adjustment at a time.
