Readfast helps you read faster without sacrificing comprehension. It uses RSVP (Rapid Serial Visual Presentation) technology to eliminate wasted eye movement by showing one word at a time, centred on your natural focal point. This lets you focus fully on the text and absorb information significantly faster than traditional reading. Most people start around 250 words per minute. With Readfast, reaching 600–750 WPM is realistic with regular use. How it works • Upload or paste any text • Hit play • Words are displayed one at a time, guided by the Optimal Recognition Point (ORP) • Adjust speed at any time and train your brain to read faster over time No skimming. No distractions. Just focused reading. What you can read • Articles from the web • Blog posts, newsletters, and long-form content • PDFs, DOCX, EPUB, TXT files • Notes, papers, and research If you can copy it or upload it, you can read it in Readfast.

Scatterbrain

Your to-do list has a lot of demands for something that has never done the laundry. Scatterbrain is a sarcastic, ADHD-friendly task planner for getting things out of your head and actually doing something with them. Capture the chaos, figure out what matters, and find a way to start—without making productivity your new unpaid job. GET IT OUT OF YOUR HEAD Brain Dump lets you type it or say it out loud. Save the thought before another one barges in and changes the subject. Give your tasks priorities that sound like actual human reactions: THE ONE THING, DO IT NOW, UGH FINE, and EVENTUALLY. Finally, an official category for the sigh. Add checklists when a task has steps. “Sort everything out” could probably use a little more detail. START WITHOUT THE COMMITTEE MEETING Can’t choose? Chaos Mode gives you one task at a time. Do it or skip it; the next one follows. The rest of the list can wait its turn. Already know what needs doing? Focus Mode puts one task and a timer on screen. Drift off, come back, carry on. Nobody is conducting a performance review. Running on very little? Bare Minimum offers ready-made tiny tasks for low-capacity days. You don’t have to turn “put a cup away” into a personal development journey. REMEMBERING EVERYTHING IS A TERRIBLE SYSTEM HEAD START warns you ahead of time. Because a reminder at the exact moment something starts is sometimes just breaking news. Vague Window lets you schedule something for “sometime this afternoon.” Some tasks need a general timeframe, not an appointment with the precision of a rocket launch. REPEAT OFFENSE handles recurring tasks. Apparently, finishing the laundry does not finish the laundry. We’re annoyed too. SOME DAYS NEED LESS APP When everything is too much, Panic Mode puts the tasks aside for two minutes of something small. You do not need a motivational speech on top of everything else. When today needs to be over, WIPE TODAY archives the unfinished stuff and resets the day. No exit interview. The Afterlife gives abandoned tasks somewhere to go. You can revisit them without keeping every old intention on today’s list. There are no streaks to break, guilt notifications, leaderboards, or digital pets depending on your attendance. Miss a day and come back when you’re ready. You do not owe your task app an apology. FREE SHOULD ACTUALLY BE USEFUL Chaos, Focus, and Panic Mode are free. Permanently. Getting unstuck is not a premium privilege. Free also includes Brain Dump, checklists, priorities, and standard reminders. You can capture tasks, choose what matters, and get on with doing them—not just admire a collection of locked buttons. Pro adds Smart Chaos, which picks your next task based on where you are and what time it is. You also get location reminders, Vague Window scheduling, stacked HEAD START warnings, and unlimited voice dumps. The extra help costs money. The way out of a bad day doesn’t. Scatterbrain works offline and syncs when you’re back online. Made by two people in Košice, Slovakia. You don’t need to get your whole life together before you can start. Let’s just do one thing.
