Atomic Habits
Every action you take is a vote
for the type of person you wish to become.
No single vote is decisive.
Sound familiar?
"I have 40 books on my Kindle I've barely touched."
"I want to read more but I can never find the time."
"I get distracted after two pages and have to start over."
"I read so slow it takes me two months to finish one book."
rielX3 is designed for exactly this. Start a book in 30 seconds. Read faster than you thought possible.
Whatever your reason for reading — rielX3 makes you better at it
"I have 3 business books I need to read before Q4."
At 400 WPM, a 300-page book takes under 3 hours. Read on your commute, at lunch, or in bed — and actually finish it.
"My mind wanders. I re-read the same paragraph three times."
OneWord mode shows one word at a time at a fixed focal point — your eyes have nowhere to wander. ADHD-friendly by design.
"I have 400 pages of required reading due Friday."
Upload your PDFs and EPUBs, jump to any section, and cover material 2–3× faster without losing comprehension.
"I want to read 52 books this year, not 12."
Train your reading speed over time. Start at 250 WPM, push to 500, then 700. Your comprehension grows with practice.
