Wikipedia

What it does

The official Wikipedia app provides mobile access to the world's largest free, collaborative encyclopedia. It allows users to read over 40 million articles across 300 languages, discover new topics through curated feeds, and for registered users, contribute by editing articles. The app is designed for both casual reading and in-depth research, with tools for saving articles and customizing the reading experience.

Where it shines

Wikipedia shines in its unwavering focus on the reading experience and its multifaceted approach to content discovery. The reading preferences panel (01:13) is a standout, offering four color themes and granular controls that demonstrate a deep respect for user comfort and accessibility. The app also excels at encouraging serendipitous learning. Instead of relying solely on search, the 'Explore' feed surfaces content through an 'On this day' timeline (11:22) and a 'Places' map (12:37), making it easy to get lost in a rabbit hole of knowledge.

UX highlights

Contextual Editing Prompts: The app masterfully avoids a mandatory sign-up. It only prompts for login when a user attempts an action like editing (01:06), creating a high-intent funnel for contributors.
Robust Reading Customization: Users can tailor their reading environment with four themes (including Sepia and true Black), adjustable font size, and even an option to dim images in dark modes (17:20).
Efficient Content Management: The Reading Lists feature allows users to save articles and organize them into custom lists (10:35), which can be synced across devices for logged-in users.
Transparent Collaboration: The 'Talk page' (02:33) and 'Revision history' (08:05) features make the collaborative and iterative nature of Wikipedia fully transparent and accessible.
Multi-Vector Discovery: The home feed offers various content modules like 'Featured article', 'Picture of the day', and 'On this day' to drive engagement beyond search.
Integrated Help System: For new editors, the app provides clear, multi-step tutorials (00:36) explaining the principles of contributing, such as citing sources and maintaining a neutral tone.

Monetization & growth

As a non-profit, the app does not feature a paywall or subscription model. Monetization is handled through donation prompts found in the user menu (16:44). Growth is driven by its established brand and mission to provide free knowledge. The app encourages community growth by prompting users to create accounts to edit and contribute, turning readers into active participants.

Who it’s for

The app serves a broad audience, from students and researchers needing a reliable reference tool to lifelong learners who enjoy exploring new topics. It also caters to a dedicated community of editors who actively maintain and expand the encyclopedia's content. Its accessibility features make it suitable for users with specific reading needs.

Notes & opportunities

The editing workflow for new users, while informative, can feel slightly daunting. The series of instructional screens and the potential to be blocked from editing a protected page (01:07) might create friction for first-time contributors. Streamlining this by offering a sandboxed editing tutorial or highlighting unprotected articles for beginners could lower the barrier to making that first edit.
