Appnull

Appnull is a speed reading application designed specifically for individuals with ADHD or those who struggle with focus. It addresses the challenge of maintaining attention during reading by displaying text one word at a time using Rapid Serial Visual Presentation (RSVP), which eliminates eye movement and helps prevent attention from drifting. The tool introduces dopamine-driven pacing with randomized speed variation, aiming to keep the reader's brain engaged through unpredictable rhythm changes. This approach is intended to help users read significantly faster—between 500 and 900 words per minute—compared to traditional reading averages.

The platform allows users to upload PDF files or paste text directly, with no account or sign-up required to begin. It features various challenge modes, including timed sessions of 1, 3, or 5 minutes, as well as a free reading mode. A 'Chaos mode' is available, where reading speed varies randomly after a warm-up period, further stimulating engagement. Users can track their progress through reading statistics such as words read, average words per minute, streaks, and session counts. Appnull also includes a global leaderboard, encouraging competition among users as a motivational tool.

Appnull is accessible on any device via the web. The service offers a free tier, which includes PDF and text upload, RSVP reading, challenge modes, leaderboard access, and three sessions of stats history. 99 per month or $39 per year, and will add features such as full reading history, WPM trends, custom themes, focus sounds, advanced challenges, and priority support. A lifetime access option for Pro is also mentioned for a one-time fee, limited to the first 200 users.

The tool positions itself as a focus-oriented speed reading solution, leveraging neuroscience principles to help users with ADHD or similar attention challenges read more efficiently.
