Achoo HTML Viewer & Inspector 4+

Tweak page, and customizable‪!‬

Designed for iPad

    • $0.99



Quickly view HTML for webpages in Safari, and even tweak them!

Achoo allows you to easily view the HTML for the webpage you're viewing in Safari. It shows the HTML (as well as any inline CSS and JavaScript) with beautiful and fast syntax highlighting.

You can share the HTML you're viewing, allowing you to easily inspect it on an external device of your choosing, or send it to a friend, or simply copy it to your clipboard.

You can edit the font if you'd like it smaller to display more information, or larger if you'd like to be able to make things out more clearly.

You can also choose to edit the contents of the webpage, allowing you to make modifications and preview how they look. Changes are not permanent, simply refresh the page in Safari to return the page to its original state after you're finished previewing your changes. (Note: you're not editing the HTML directly, rather it's a visual editor of the contents of the page)

As a bonus, it includes a variety of alternate home screen icons so you can customize the app to your liking beautifully.

A “find in source” option would be great

Since there’s nowhere to send feature requests (and I suspect this app is not in any sort of active development), here’s a review:

It works great, looks very nice and clean, and the edit page option is very smooth. It would be perfect if I could search within the html, and as somebody else mentioned, text wrapping.

The lack of word wrap may be a dealbreaker

Overall, this Safari extension ostensibly does what it says on the tin.

But there are three downsides that should probably be aware of, which I’ve listed below in order from least bad to most bad:

1. It isn’t great that this extension doesn’t let you configure whether to show in light mode or dark mode—it only ever follows the system setting.

2. Unless I’ve missed it somewhere, it doesn’t seem possible to be able to trigger this extension from share sheets. Now, you might be wondering why you’d ever need to do that since this extensions available through Safari‘s extensions dropdown—but if you might ever be looking at a webpage within a Safari webview (such as a webpage that you’re looking at within the Twitter app), then you know that there’s no access to the Safari’s extensions dropdown within those sorts of webviews.

3. There’s no way to enable word wrap. Which might be kind of a dealbreaker since so many sites are procedurally generated these days. So for all but the most straightforward use cases, this downside may well be a dealbreaker.

All that being said, this app has good bones and good promise. And if the developer might be able to resolve some of these downsides, it could easily become a five-star app.

Disappointingly few features

This extension does exactly what the description says, and nothing more. Inline HTML, CSS, JS only. Copy edits can only be made on-page, in a WYSIWYG-type editor. HTML, CSS, JS edits are not allowed, though they are implied in the description.

This is not a replacement for the dev options that we expect on all modern desktop browsers. I hope that one day we have an ipad extension (or native tools) allowing this functionality without connecting iPad to a desktop computer.

For now, this is not the solution I'm working for. Take the description at it's word and don't hope for any more, even standard, features.
