What's New in FontFlex

4.8.15

August 14, 2026

FontFlex: Fonts for Safari This update is all about accessibility — because FontFlex should work for everyone, no matter how you read or navigate your phone. VoiceOver users can now hear exactly what every font, size, weight, and style control does. These controls were previously silent to VoiceOver — that's fixed. Buttons you tap often (close, favorite, dismiss) are now bigger and easier to hit. Text throughout the app now resizes properly when you increase your device's text size in Settings. Onboarding animations now respect Reduce Motion, so they won't play if you've turned that on. We also fixed several places where text was showing in English even when your device language wasn't — more of the app now displays correctly in your language. Thanks for reading with us.

Older eyes? You need this

Well-designed tool which makes it easy to tune websites for legibility (and easy to turn it off for the sites which refuse to play nicely).

How to upload custom fonts

So far the app works perfectly, it changes fonts, but is it possible to install custom fonts?

Thank you for the great feedback

Suscripción

Cambiaron a un modelo de suscripción, no entiendo el por qué. No hay forma de comprar la versión de por vida, sin mencionar que el precio de la suscripción anual es excesivo para lo que hace.
