LettersPractice

LettersPractice is a web app that teaches young children to read, aimed at ages two to five and up, using a spaced-repetition system the team calls SRS++. Instead of drilling flat flashcards, it runs short daily sessions where friendly characters called LetterPeople introduce letter names, sounds, and the words those sounds build. The whole thing is framed around early literacy for every child, and it's designed to slot into a few quiet minutes of a family's day rather than demand a lesson block. The result feels less like a worksheet and more like a short visit with a cast of characters who each carry a sound.

Early reading is really a memory problem underneath. A child meets a letter or a sound, then loses it if they don't see it again at the right moment, and most apps just pile on more content and hope some of it lands. LettersPractice leans on the idea that learned concepts fade if they aren't revisited at the right intervals, so it schedules each concept to come back just before a child is likely to forget it. The practice compounds across sessions rather than resetting every time they open the app, which is the same reason spaced repetition works for adults learning languages and, here, for kids learning letters. The scheduling stays invisible to the child, who just sees the same friendly faces turning up again at the right moments.

Under the hood it gives every item an ELO-style rating and runs a review scheduler that works out the next time a child should see it. As the child answers, the system updates that rating and books the next review, which is the science-backed part the site leans on. Sessions are short by design, roughly two to five minutes, so it fits a young attention span and a busy parent's day without becoming a battle, and reviews can be scheduled for classroom use as well as at home. Because the difficulty adjusts to each child, an easy item fades from the rotation while a shaky one comes back more often.

A deliberate choice here is that children can't mindlessly click through. Exercises like filling in the missing letters require an authentic, correct response before anything advances, so screen time turns into real practice instead of tapping to the next screen. There's no reward for guessing quickly, which keeps a toddler from learning to game the app rather than the letters. Each session ends with a quiet animation of the letters working on their hobbies, a small payoff that keeps kids wanting to come back without turning the whole thing into a loud, prize-driven arcade that trains the wrong instinct.

The curriculum unfolds in stages rather than dumping everything at once. Early on it's letter sounds and simple word-building, and later stages open up fuller spelling exercises and more independence as a child is ready for them. It adapts to where a child actually starts, whether that's a first-time learner with nothing unlocked yet, one who already knows some letter names and sounds, or one who can read a handful of words on their own, so the same app suits a two-year-old and an older sibling on different footing. That staged release also means the app grows with a child instead of being outgrown in a week.

It fits parents of toddlers and preschoolers who want a calm, structured way to build reading at home, and it deliberately avoids the loud, ad-heavy arcade feel a lot of kids' apps default to. Where it stands apart from typical early-reading apps is the memory engine sitting underneath, which treats retention as the core problem to solve rather than an afterthought bolted onto a pile of games. The characters and animations are the friendly surface, and the scheduler is the actual product doing the work. That focus on remembering, not just exposure, is what separates it from an app that simply shows a child a lot of letters and moves on.

Access is a one-time purchase rather than a subscription. You get a free month to try it with your child, and after that lifetime access is a flat twenty dollars, handled through Stripe, with no recurring bill. For a household weighing whether a reading app is worth it, the trial covers a full month before any payment, and the price is a single charge you pay once rather than another monthly line item that quietly renews in the background. For a tool a child might open daily for a year or more, a one-time price lands differently than a subscription that keeps charging long after the novelty wears off. Since it runs in the browser, there's nothing to install and it works on whatever device the family already has to hand.
