Your memory isnβt born; itβs built. Numery gives you control over everything you always forget: phone numbers, passwords, birthdays, historical factsβ¦ All using historically proven methods employed by memory geniuses. Reduce your COGNITIVE DECLINE. Counterbalance AI usage. Several scientific studies agree that the more you use your memory, the longer youβll maintain your cognitive abilities intact. Nowadays, we delegate so much cognitive processing to AI that our brains become lazier. And if we donβt act now, by the time we want to reverse the negative effects, it will be too late. What you can do with Numery: β’ Major System β turn numbers into memorable words and mental images, with clear rules. β’ Spaced repetition quizzes β review at just the right times to lock in what youβve learned without overwhelm. β’ My Numbers β save what matters to you β’ Converter and simulator β practice encoding and decoding until it becomes automatic. β’ Challenges β donβt just memorize what you already know, memorize much more. β’ Languages β Numery supports English, Spanish, French and Italian. Privacy as the foundation Your study data never leaves your devices to train models or for third-party analytics. EVERYTHING stays on your devices. Train with peace of mind. Numery is developed by an independent developer. Your feedback and suggestions help shape future updates. If you find the app useful, a rating would mean a lot.

Pith

Pith helps you remember what you study, and stays out of the way while you do it. Make a card, or bring in the decks you already have, and let spaced repetition resurface each one at the moment you are about to forget it. No streaks to keep alive, no clutter. Just the next card, at the right time. It is built to feel like a small-press notebook rather than another grey app screen: serif type, warm paper tones, and a study flow with nothing in your way. REMEMBERS FOR YOU Every card is scheduled with FSRS, the modern spaced-repetition algorithm, so reviews land right before recall would slip. Prefer the classic method? Switch to SM-2 in a tap, and imported decks keep their own schedule. BRING YOUR DECKS Already use Anki? Import your .apkg files with cards, media, and progress intact, then export back out the same way. Spreadsheets come in too, through CSV or TSV. MORE THAN WORDS Add images, record or attach audio for pronunciation, and choose the card type that fits the material: basic, reversed, type-the-answer, cloze deletions, or image occlusion for diagrams and maps. BUILT FOR BIG DECKS Thousands of cards stay fast. Browse, search inside a deck, and study large imported sets without the app slowing down. SEE YOUR PROGRESS Retention rate, review history, a study heat map, and an upcoming-reviews forecast, each broken down per deck. ON EVERY APPLE DEVICE A native app for iPhone, iPad, and Mac, with a Today widget that keeps your reviews one glance away. PRIVATE BY DESIGN No account. No ads. No analytics or trackers of any kind. Your cards stay on your device, and with Pith Pro they sync through your own iCloud, which we never see. FREE, WITH ONE OPTIONAL UNLOCK Free includes one deck with unlimited cards and the full study experience. Pith Pro is a single $5.99 purchase, never a subscription. It unlocks unlimited decks, iCloud sync across your devices, and the cloze and image-occlusion card types. Questions or ideas? Email claudiu.sararu@gmail.com.

The clearest difference is iOS requirement: Pith at 18.0 against Numery's 26.0. On price, ads, in-app purchases and device support there is nothing between them.
