Most reading apps count pages. ReadPace counts whether you actually understood them. Start a session, read the way you normally read, then scan the pages you finished. ReadPace turns that into a real words-per-minute number — not an estimate, not a guess. Then it asks you questions about what you just read, written from those exact pages. Speed means nothing if none of it stuck. ReadPace measures both. TIME IT. SCAN IT. KNOW IT. Hit start, read, hit "Finish & scan." Your session becomes a precise WPM number, logged against the book you're reading. No manual page counts, no stopwatch math. READ IT. THEN PROVE IT. Every session can end with a comprehension test built from the pages you just covered. Real questions about the actual ideas — not trivia. Not sure? Tap "No idea." Honest answers make your data honest. GET SCORED, THEN GET BETTER. See your comprehension percentage, your WPM, and how many you got right — side by side. Then review every question: what you answered, what was correct, and why. Misses get explained, so the test teaches you something too. FIND THE SPEED WHERE YOU REMEMBER MOST. This is the one no other reading app can tell you. ReadPace groups your tested sessions into speed bands and averages your recall in each, revealing your personal sweet spot — the pace where you're fast and you retain it. It also shows you where recall starts to fall off, so you know exactly when you're reading too fast to learn anything. WATCH THE LINE CLIMB. Your WPM trend over 7 days, 30 days, or all time, with your goal line drawn right across it. Weekly session goals, personal bests, and a running average that proves the last three months weren't your imagination. INSIGHTS THAT CHANGE HOW YOU READ. • Your most productive time of day — morning, afternoon, or evening • Which categories you read fastest, and which you remember best • Week-over-week change, personal best, total sessions at a glance EVERY BOOK ON YOUR SHELF, MEASURED. Your library tracks each title separately: lowest, average, and highest speed, average comprehension across every tested session, a speed curve across the whole book, and a full session log with words read, time spent, WPM, and recall score. WHO IT'S FOR Students who need it to stick. Professionals reading to stay sharp. Anyone with a shelf of non-fiction and a nagging suspicion they're not retaining much of it. And anyone who just wants to read faster — with proof they haven't sacrificed understanding to get there. Stop guessing how fast you read. Start knowing what you keep.
