REAL IMPACT Join thousands of users who have transformed their web reading experience. FontFlex makes the internet more accessible, comfortable, and enjoyable for everyone – regardless of visual abilities or reading preferences. Whether you're reading articles, studying online, or browsing your favorite sites, FontFlex helps you read with clarity and confidence. READ EVERY WEBSITE YOUR WAY Make the font size bigger or smaller on any web page, and it stays that way the next time you visit. Switch to a clean sans serif typeface when a site's default is hard to follow, or choose a serif when you want a calmer, book-like page. Turn on dark mode colors for night reading, or a warm cream background to take the glare out of long articles. Everything happens inside Safari. There is no second browser to learn and nothing to copy or paste - open a page the way you normally would and your typeface, size and colors are already applied. BUILT FOR EVERY READER - Low vision and large print readers who need text bigger than a site allows - Students reading long articles and research pages in the browser - Older readers who would rather not zoom in on every single page - Night readers who want a darker page and softer contrast - Designers and developers checking how a page looks in another typeface ON ALL YOUR DEVICES Optional iCloud sync keeps your fonts, colors and profiles the same on iPhone, iPad and Mac, so a site you set up once reads the way you want everywhere. SUBSCRIPTION OPTIONS • Weekly: $4.99 USD • Yearly: $24.99 USD Payment charged at confirmation. Subscriptions auto-renew unless turned off 24 hours before period ends.

Fake reviews. 25/year. No thanks. *2026-06-05, version 4.8.2* So broken. Fake reviews. 25/year. No thanks. ### 5/5 — すごい *2026-05-30* Google fontが読み込めるし、自分で用意したカスタムフォントも(10MBまで)使える。めっちゃいいです。 **Developer response:** レビューありがとうございます！アプリがお役に立ててとても嬉しいです。ご利用に感謝します！ English: Thanks so much for this! Really glad the app is helping you. Appreciate the support! ### 5/5 — Indispensable pour personnaliser Safari, accessible à tous ! *2026-03-09* FontFlex est une application exceptionnelle pour tous ceux qui aiment personnaliser leur expérience de lecture sur Safari. Le choix de plus de 1 500 polices Google est impressionnant, et la possibilité de changer la taille, le style, la couleur et même l’interface de l’app est un vrai plus. L’organisation par catégories (serif, sans-serif, monospace, manuscrite, etc.) rend la navigation très agréable. Un aspect que j’apprécie particulièrement : FontFlex peut vraiment aider les personnes en difficulté de lecture, comme celles atteintes de dyslexie ou de troubles visuels. Grâce à des polices adaptées (comme Atkinson Hyperlegible ou des polices « dyslexia-friendly »), chacun peut adapter Safari à ses besoins et rendre la lecture sur le web beaucoup plus confortable et inclusive. C’est une vraie avancée pour l’accessibilité numérique ! Pour aller encore plus loin, j’adorerais pouvoir filtrer les polices selon leur style ou leur usage (par exemple : « manuscrite », « pour titres », « élégant ») et surtout selon la prise en charge linguistique, comme « adaptée au français » ou « avec accents », à la manière de Google Fonts. Ce serait génial de pouvoir trouver facilement les polices qui conviennent parfaitement à la langue française ! En attendant, il m’arrive de devoir « farfouiller » sur Google Fonts depuis un autre appareil pour repérer des polices qui me plaisent, car ce n’est pas pratique sur l’iPhone et il m’arrive d’oublier celles que j’avais trouvées. Une fonction de recherche avancée et la possibilité de sauvegarder ses polices favorites directement dans FontFlex rendraient l’expérience encore plus fluide. Enfin, j’espère qu’un jour il sera possible, grâce à cette app, de personnaliser les polices de toutes les applications et de l’ensemble d’iOS, pas seulement Safari. Ce serait un rêve pour tous les passionnés de typographie et un vrai plus pour l’accessibilité ! Bravo aux développeurs pour cette app déjà très aboutie, qui rend Safari unique, agréable et accessible à tous. Quelques options de recherche avancée rendraient FontFlex absolument parfaite ! Réponse au développeur: Bonjour, Merci beaucoup pour votre réponse, j’apprécie vraiment! Votre message est parfaitement rédigé, on ne devinerait pas qu’il a été traduit — bravo 👍🏻 J’en profite pour vous préciser un point concernant la synchronisation : malheureusement, je ne peux pas utiliser iCloud, car mes 5 Go de stockage sont saturés et il m’est impossible de faire de la place ou de récupérer mon ancien contenu. J’utilise actuellement TeraBox, qui offre 1 To de stockage gratuit, et j’adorerais pouvoir synchroniser mes favoris avec une alternative à iCloud. Encore merci pour votre travail remarquable et votre écoute. Bonne continuation et au plaisir de découvrir les prochaines évolutions de FontFlex ! Edit mars 2026: la nouvelle mise à jour a l’air super, j’ai hâte de tester. **Developer response:** Merci beaucoup pour ce super retour ! Je suis vraiment content que tu apprécies FontFlex — et ça me touche de savoir que l’app aide aussi côté accessibilité. Tes idées sont excellentes : le filtrage par style (je vais clairement m’inspirer de Google Fonts !) et l’enregistrement des favoris avec la synchronisation iCloud, c’est tout à fait faisable. Je vais m’y mettre ! Juste pour info : cette réponse est traduite automatiquement, car le français n’est pas ma langue maternelle. Merci pour ta compréhension ! Encore merci d’avoir pris le temps de partager ton avis ! ### 5/5 — Older eyes? You need this *2026-02-28* 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). ### 4/5 — How to upload custom fonts *2026-02-19, version 4.6.3* So far the app works perfectly, it changes fonts, but is it possible to install custom fonts? ### 5/5 — Old Eyes’ Balm *2026-02-16* Always improving, it enables more legible fonts for a default plus site-specific improvements **Developer response:** Thank you for the great feedback ### 1/5 — Suscripción *2025-11-13, version 4.5.0* 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. ### 3/5 — Works only intermittently and not on all fonts on the page *2025-11-09, version 4.4.17* I installed this extension to increase the size and change the font of letters in my gmail inbox in Safari. It only worked intermittently, and sometimes, for some entries in the inbox and not others. Turning the extension on and off in Safari sometimes worked intermittently, as did closing Safari and reopening it, but I could not get the font changes to remain stable. ### 5/5 — Always improving *2025-10-27* Makes most websites comfortable to read. Permits fine control over settings. Worth every penny **Developer response:** Thank you for the feedback. We are happy that FontFlex has been helpful ### 5/5 — Love it *2025-10-10* This is very reliable and works exactly how I want it to, idk what I'd do without it 💓💞💓 I've been using this for like a year and I'm not sure if I left a review so I'm doing it now :D **Developer response:** Thank you for the feedback. In the latest release, we added OpenDyslexic Alta as a custom free font. ## Frequently asked questions about FontFlex ### What does FontFlex for Safari do?

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, favourite, 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.
