## What is Navidys?

Make the web more comfortable to read.

Navidys is a Safari extension that reformats web pages to your reading preferences: spacing, font, size, zoom and colors — adjustable site by site.

WHY SPACING MATTERS
In a controlled study published in PNAS (Zorzi et al., 2012), increasing the space between letters immediately improved reading accuracy in children with dyslexia. Navidys gives you precise control over letter spacing and line spacing on every web page.

FEATURES
- Apply your style to web pages individually
- Adjust the spacing between letters and between lines
- Change the font — 16 choices including Dyslexie (created by Christian Boer for dyslexic readers; font choice is a matter of personal comfort), Helvetica, Andika Basic, Luciole, AccessibleDfA, Sylexiad, Verdana and more
- Adjust font size and zoom on any page
- Choose text and background colors for better contrast and visual comfort
- Install the typefaces on your device to use them in other compatible apps

Navidys is an accessibility and comfort tool. It does not diagnose or treat dyslexia.

Your suggestions are welcome!

### 1/5 — Scam

*2026-01-16*

This £7:99 app does not work. It is just a scam and I am very disappointed with Apple for hosting this product.

### 1/5 — Instruction

*2025-12-13*

Les instructions pour l’installation sont incomplet je ne suis pas en mesure d’utiliser l’APP meme avec safari sur un Mac book air et IOS je souhaitait installer la fonte Eido Mono… perdu mon argent et mon temps

### 4/5 — What it does is good, but could use some enhancements

*2025-04-08*

Pros...
-can change background color of web page
-can change letter/word spacing on web page 
-can change font on web page

Cons...
-can't use all fonts that are active on the device - can only use some fonts (think around 17), which does NOT include Times New Roman 
-you HAVE to change the font (you can NOT use the original font more spaced out, for example)
-a lot of trial and error may be required to get a page to be suitable (in contrast with the built in zoom options where you can see the changes right away) [not the developer's fault, but still annoying] 
-not persistent (only good till you refresh the page, then you have to apply again) [dont think this is the developer's fault either but still annoying to have to apply the style for EVERY page] 
-can only set one style at a time

### 1/5 — iPhone and iPadOS versions aren't automatic

*2022-06-15*

I bought this thinking the ipad and iphone versions would be the same, sadly they are not.

### 1/5 — Doesn’t work

*2022-05-25*

You can’t put it to your whole phone. I couldn’t read the reviews before hand. Nope I want my money back.

### 3/5 — Lost all the text format

*2022-01-01*

I’m happy with this app that can change the text font and font size in website, but I’m not happy with the simple “just replacing all the text style” strategy. There are formats in a text paragraph, such as emphasis content, quotes or even advertisements between real contents (in a different color or text style), but by applying this app, all the text format are disappeared, which actually makes it harder to read. Why? Because all the visualizations of the relationship between different contents are lost. I would highly suggest the developers to learn more about publishing and improve this plug-in’s function, maintaining the visualization of texts.

**Developer response:** Hello,
Thank you for your very interesting feedback. In fact, we are currently losing some formatting, because all the fonts offered do not allow the use of bold or italics. It can also be noted that italics does not make reading easier for some people. Can you tell me, by email, your profile and the settings that you think are suitable? 
Michael

### 4/5 — Great app, but please don't overwrite colours by default

*2021-08-07*

Great app, but please don't overwrite colours by default - many sites use multiple background colours

**Developer response:** Thanks for your review. It's now possible !

### 4/5 — Almost Perfect!

*2021-02-17*

I was on the fence about spending this much on an app that there aren’t many reviews on. But I was pleasantly surprised to see it work! Only thing is you have to apply it to every page you bring up. Tap a link, have to apply the font again, Dyslexie in my case. Would be awesome for a future update to correct this if possible! But for any long reads this is a life saver! The dyslexic fonts help me a lot in reading speed and retention! Have to play with the settings a bit to get it to look perfect with some links but this is the best thing I’ve found so far! Thanks so much for creating this!!!🙌🏻🙌🏻 ❤️

**Developer response:** Thank you for your feedback, your feedback comforts me in my goal of helping people to read and understand texts. Unfortunately on iPhone it is not possible to apply styles to pages automatically. On the other hand, it is possible on Mac.

### 5/5 — Wonderful

**Developer response:** Thanks ! ❤️
