Normally, I bang on endlessly about Web Accessibility, but occasionally branch out to bore about other things. For Global Accessibility Awareness Day last week, my employers at Babylon Health allowed me to publish a 30 min workshop I gave to our Accessibility Champions Network on how to make accessible business documents. Ok, that might sound dull, but according to I.M.U.S., for every external document an organisation publishes, it generates 739 for internal circulation. I’m using Google Docs in the talk, but the concepts are equally applicable to Microsoft Word, Apple Pages, and to authoring web content.
It’s introduced by my Professional Better Half, Taylar Bouwmeester –recipient of the coveted “Friendliest Canadian award” and winner of a gold medal for her record of 9 days of unbroken eye contact in the all-Canada Games– and then rapidly goes downhill thereafter. But you might enjoy watching me sneeze, sniff, and cough because I was under constant assault from spring foliage jizzing its pollen up my nostrils. Hence, it’s “R”-rated. Captions are available (obvz) – thanks Subly!
I am a UK-based web developer and accessibility consultant, specialising in ensuring web sites are inclusive for people with disabilities or who experience other barriers to access–such as living in poorer nations where mobile data is comparatively expensive, networks may be slow and unreliable and people are generally accessing the web on cheap, lower-specification devices.
Although I am UK-based, I have clients around the world, including the USA. And, of course, because the biggest mobile platforms are Android and iOS/iPad, I am affected by the regulatory regime that applies to Google and Apple. I write in a personal capacity, and am not speaking on behalf of any clients or employers, past or present. You have my permission to publish or quote from this document, with or without attribution.
Many of my clients would like to make apps that are Progressive Web Applications. These are apps that are websites, built with long-established open technologies that work across all operating systems and devices, and enhanced to be able to work offline and have the look and feel of an application. Examples of ‘look and feel’ might be to render full-screen; to be saved with their own icon onto a device’s home screen; to integrate with the device’s underlying platform (with the user’s permission) in order to capture images from the camera; use the microphone for video conferencing; to send push notifications to the user.
The benefits of PWAs are advantageous to both the developer (and the business they work for) and the end user. Because they are based on web technology, a competent developer need only make one app that will work on iOS, Android, as well as desktop computers and tablets. This write-once approach has obvious benefits over developing a single-platform (“native”) app for iOS in addition to a single-platform app for Android and also a website. It greatly reduces costs because it greatly reduces complexity of development, testing and deploying.
The benefits to the user are that the initial download is much smaller than that for a single-platform app from an app store. When an update to the web app is pushed by a developer to the server, the user only downloads the updated pages, not the whole application. For businesses looking to reach customers in growing markets such as India, Indonesia, Nigeria and Kenya, this is a competitive advantage.
In the case of users with accessibility needs due to a disability, the web is a mature platform on which accessibility is a solved problem.
However, many businesses are not able to offer a Progressive Web App, largely due to Apple’s anti-competitive policy of requiring all browsers on iOS and iPad to use its own engine, called WebKit. Whereas Google Chrome on Mac, Windows and Android uses its own engine (called Blink), and Firefox on non-iOS/iPad platforms uses its own rendering engine (called Gecko), Apple’s policy requires Firefox and Chrome on iOS/iPad to be branded skins over WebKit.
This “Apple browser ban” has the unfortunate effect of ham-stringing Progressive Web Apps. Whereas Apple’s Safari browser allows web apps (such as Wordle) to be saved to the user’s home screen, Firefox and Chrome cannot do so–even though they all use WebKit. While single-platform iOS apps can send push notifications to the user, browsers are not permitted to. Push notifications are high on business’ priority because of how it can drive engagement. WebKit is also notably buggy and, with no competition on the iOS/iPad platform, there is little to incentivise Apple to invest more in its development.
Apple’s original vision for applications on iOS was Web Apps, and today they still claim Web Apps are a viable alternative to the App Store. Apple CEO Tim Cook made a similar claim last year in Congressional testimony when he suggested the web offers a viable alternative distribution channel to the iOS App Store. They have also claimed this during a court case in Australia with Epic.
Yet Apple’s own policies prevent Progressive Web Apps being a viable alternative. It’s time to regulate Apple into allowing other browser engines onto iOS/iPad and giving them full access to the underlying platform–just as they currently are on Apple’s MacOS, Android, Windows and Linux.
Developing a Report on Competition in the Mobile App Ecosystem – The U.S. National Telecommunications and Information Administration is preparing a Report on Competition in the Mobile App Ecosystem, following Biden’s Executive Order to address the problem of “dominant tech platforms undermining competition and reducing innovation”. Includes PWAs and #AppleBrowserBan in scope.
