Благодарю. Как запомнить выбранный размер шрифта на сайте? Что бы после обновления страницы по новому не увеличивать шрифт. ### 5/5 — Saved my iPhone *2019-04-23* I was ready to switch back to Android because of the inability to increase font size in Safari. Such a basic function! This app saved the day. Just read the instructions and it’s very easy to use. On certain pages, like Twitter, it only increases part of the page, but I imagine that’s due to how the page is formatted rather than the app. Well worth every penny. ### 3/5 — Reset *2019-03-23* It is really good if doesn’t reset to original size each time you open the website ### 4/5 — Ottimo *2019-03-21* Molto comodo ingrandire il font ### 5/5 — Outstanding app *2019-03-20, version 2.0* For anyone having problems reading on the IPad this is a wonderful app. Resizing the screen is not always available for many websites. This app comes in very handy particularly when reading news websites . Great for seniors! ### 5/5 — Very Good *2019-02-06* I didn’t know this could exist. It does work Shame on Apple that we have to depend on another app to be able to increase the font size in Safari ### 4/5 — Works great, could be better *2019-01-23* Works very well for increasing font sizes on web pages. If possible, it would be better if the increments were more like 10 or 15 rather than 25. ### 1/5 — Don’t remember *2018-09-24* It works but it’s a headache also. Must adjust font size every time (After refreshing page or navigation to other page of same web). ### 5/5 — Works iPhone X Safari *2018-09-17, version 2.0* So glad that this app works with the iPhone X, as the Safari font was entirely ti small. As usual with Apple, they completely miss some of the most obvious needs, thankful this app still works. ## Frequently asked questions about Font Size App Extension ### How do I activate Font Size App Extension in Safari?
