Memory

You're not bad with names. Nobody taught you how. Memory is short, daily memory training built on the mnemonic techniques memory champions use. Each session takes about 3 minutes, and you try your first technique in 60 seconds. No sign-up needed. WHAT YOU'LL LEARN • Remember names and faces: the Feature-Hook method links a face to a name with one vivid picture. Practice with illustrated faces, then with the people you really meet. • The Link Method: memorize a grocery list or a to-do list as one story you can walk through forwards and backwards. • Number shapes for PINs and codes: turn digits into pictures and short stories. You practice with sample codes; Memory never asks for your real PINs. • The Major System: turn every number from 00 to 99 into a word, then use your Major System peg words to memorize phone numbers and longer numbers. HOW THE LESSONS WORK • Bite-sized lessons: learn a hook, test it, then use it in a realistic scene. • Smart review with spaced repetition brings each hook back before it fades. Reviews never cost hearts. • Real-life missions help you use a technique outside the app, like recalling a new colleague's name. • People I Met: save the people you meet with their name hook and review their names later. • A missed day never erases what you've learned, and streak freezes protect your streak. WHY IT'S DIFFERENT • Real mnemonic techniques studied in cognitive psychology, not brain games. • Results you can see: the app shows how many names and numbers you actually recalled. • No account and no face recognition. The people you save stay on your device. • You can delete your data inside the app at any time. LEARN FOR FREE, GO PRO IF YOU WANT MORE Every lesson and every review is free. Lessons use hearts that refill over time, and you can earn hearts back with a short practice set or an optional ad. Memory Pro removes ads and adds unlimited hearts, extra streak freezes, a longer streak repair window and unlimited People I Met. Plans: yearly with a 7-day free trial, monthly, or a one-time lifetime purchase. The price is shown in your currency before you buy. Payment is charged to your Apple Account when you confirm the purchase; with the free trial, when the trial ends. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel them anytime in your Apple Account settings, and we remind you before your trial ends.

Verdict
The clearest difference is ads: Sophia at none against Memory's shown. Memory's advantage is iOS requirement (16.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.
