Whether you are a teacher, a parent, an accessibility designer, or a curious self-learner, DotSense gives you a clear path from your first dot to confident grade 2 reading. WHAT YOU CAN DO Lessons that actually build skill Phase by phase, you move from the braille alphabet to numbers, punctuation, and grade 2 contractions. Each lesson is short, focused, and ends with a quick check so the learning sticks. Flash cards for instant recognition See the dot pattern, name the letter. Flash cards train your eye to read braille at a glance, the same way fluent readers do. Word practice Spell real words letter by letter in braille. Word practice bridges the gap between knowing letters and reading actual text. Speed drill Timed challenges push you past slow recognition into real fluency. Track your accuracy, beat your best time, and watch the seconds drop. Free type Open the braille keyboard and type freely. Perfect for experimenting, drilling tricky letters, or showing a friend how braille works. Reading mode Practice reading short passages in braille so you can connect single letters to flowing text. Daily Challenge and streaks Five new words a day. A streak you actually want to protect. Mastery overview that shows exactly which letters need more love. WHY DOTSENSE Built for focus, not noise A calm dark interface, no flashing rewards, no manipulative loops. Just a tool that respects your time. Progress you can trust Every session feeds an honest mastery view. You see which letters you have nailed, which need more reps, and exactly where to practice next. Works for sighted learners and visual learners alike DotSense teaches the braille system itself. You learn the dot patterns, the letter mappings, and the contractions used in Unified English Braille (UEB) and grade 2. Offline friendly Lessons, flash cards, and drills work without a connection, so you can practice on a flight, on the train, or anywhere else.
