What It Is

Accessibility up to 11 is a personal knowledge site maintained by iOS Developer & Accessibility Advocate Daniel Devesa Derksen-Staats, with a core focus on accessibility development for iOS apps. The site centers on “Developing Accessible iOS Apps” and #365DaysIOSAccessibility, covering articles, daily tips, talks, podcasts, and links to publications. The author has accumulated mobile accessibility experience across teams such as Apple, Spotify, Skyscanner, and the BBC, so the site feels more like an expert-curated learning resource library than a traditional online course platform.

Core Features

The website mainly provides practical iOS accessibility content, such as accessibility labels, accessibility traits, VoiceOver, Switch Control, Voice Control, SwiftUI/UIKit keyboard shortcuts, and spatial experiences in visionOS. Its value lies in translating abstract accessibility principles into actionable checkpoints and API usage recommendations for developers. The site also collects the author’s articles, podcast interviews, conference talks, and book links, making it suitable for deeper learning around specific questions.

Pricing

Based on the available site content, the articles, daily tips, talks, and podcast links are primarily free to access. The main commercial content is the author’s book, Developing Accessible iOS Apps, which is sold through external channels such as Apress/Springer and Amazon. Exact pricing depends on the purchasing platform. The website itself does not show subscriptions, memberships, enterprise training pricing, or course packages.

Pros and Cons

The main advantage is its highly vertical focus on iOS Accessibility, with strongly practical content. It is especially suitable for developers who already know how to build iOS apps but are unsure how to start improving accessibility. The author emphasizes “progress over perfection,” which lowers the psychological barrier to getting started. The downside is that it is not a structured teaching product: there is no learning progress tracking, exercise system, certificate, or Q&A support. The content is primarily in English, so Chinese-speaking teams may need to spend time translating and digesting it. In addition, its coverage is focused on iOS, offering limited help for Web, Android, or cross-platform accessibility.

Who It’s For

It is best suited for iOS engineers, mobile technical leads, product designers, QA testers, and development teams that are building an accessibility culture. It can also serve as a source of internal training materials, supplementing the more scattered practical guidance found in Apple’s official documentation.

Access in China

Judging from the domain and content format, this is a standard static knowledge site and does not appear to rely heavily on restricted services for its core functionality. It is expected to be directly accessible from mainland China. However, some external links, such as YouTube, Spotify, certain podcasts, or social platforms, may not open normally in mainland China, so the overall experience may be “main site available, some external resources limited.”
