Two cards face down. You flip them, remember where they are, and find the pair. Three seconds in, your visual and spatial memory is already at work. Recall Trainer is that simple challenge, built for learning and for training, from the first years to the grandparents. This complete edition includes everything, with no ads and no in-app purchases. WHO IS IT FOR? • Toddlers: card packs to recognize animals, food and faces, then letters, numbers and first words. A voice says what they flip, in English or in the language you choose. A real early-learning game for preschool. • Kids: learn to read by pairing a picture with its word, to count by linking a number with its name, to match a lowercase letter with its uppercase, to discover a foreign language pair by pair. • Adults and seniors: a brain training session of a few minutes a day. The big boards, up to 78 cards, demand attention, concentration and a working memory in good shape. WHAT MEMO TRAINS Visual memory, because you have to recognize the pictures. Spatial memory, because you have to remember where they are. Auditory memory, because every card can be read aloud. And concentration, because a 78-card board is never won while thinking about something else. FOUR WAYS TO PLAY • Classic: 25 levels, from 2 to 78 cards, in five difficulty bands. • Time Attack: start with 30 seconds; every pair adds time and every cleared board adds a bonus. • 2 Players: take turns on the same device, the perfect memory duel between a child and a parent, with no limit on games. • Educational: 25 ready-made activities to read, count, memorize or discover a language, plus a custom mode where you pick the image, text, voice and language of each side. TEN CARD PACKS, ALL INCLUDED Animals, food, music, sports, faces, emojis, numbers, words, lowercase and uppercase letters: more than 1,000 cards, available from the first launch. No ads, no in-app purchases, nothing to unlock: you pay once and that is all. ALSO • Card backs, decorations and layouts to unlock by playing. • Progress kept on all your devices with iCloud. • Available in 24 languages, on iPhone and iPad. Recall Trainer keeps its familiar wood-and-slate look in a refreshed interface. The edition you install on the family tablet and keep for years.

Verdict

The call

The clearest difference is price: Words at Free against Recall Trainer's $8.99. Words also leads on rating (4.5 vs 3.8) and ratings volume (1.1K vs 5). Recall Trainer's advantage is in-app purchases (none vs 10) and review sentiment (78% vs 50%). On ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Words holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Words has 1.1K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 50% of Words's written reviews are positive against 78% of Recall Trainer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Words ships an update every 5 weeks, Recall Trainer fortnightly. The most recent releases landed on November 9, 2026 and November 6, 2026 respectively.
