Numery gives you control over everything you always forget: phone numbers, passwords, birthdays, historical factsβ¦ All using historically proven methods employed by memory geniuses.

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.

Lociform

A memory palace is the oldest study technique there is. Lociform makes it practical. Type what you need to remember. Lociform binds each item to a spot in a place you already know, with a vivid image that actually interacts with that spot. Then it walks you through the route out loud and brings each item back on a spaced-repetition schedule. WHY PUT THINGS IN PLACES Your memory for places is far better than your memory for lists, so you smuggle the list into a place. Roman orators used this to deliver speeches without notes. When Eleanor Maguire's team scanned ten of the highest-ranking competitors at the World Memory Championships in 2003, nine of the ten were using the method of loci, and they were not smarter than the controls and their brains were not structurally different. FREE, WITH TWO PALACES - A worked sample palace, one tap from first launch - A three-minute before-and-after test, so you see your own two scores - Starter decks: the 12 cranial nerves, the 8 carpal bones, the Krebs cycle, the NATO alphabet - Memory Walks read aloud while you look at each locus - Spaced repetition built on FSRS-6, showing the real interval on every button - Build a palace from your own photo, rendered with real depth - Full VoiceOver support, and a designed flat mode for Reduce Motion VERIFIED, NOT GUESSED For factual material Lociform uses a human-written hook library, each entry carrying the etymology that justifies it. Scaphoid is a boat because scaphe is Greek for boat. On-device Apple Intelligence is only ever asked to phrase a hook it has been handed, never to invent a medical association. Every scene is labelled so you can see where it came from. PRIVATE BY CONSTRUCTION No account. No servers. No analytics. No third-party SDKs of any kind. Lociform makes no network requests at all. The depth model and the language model both run on your iPhone, so your palaces, your photos and everything you memorise stay on the device. ONE OPTIONAL UNLOCK Every feature is free. If you want more than two palaces, Unlimited Palaces is a single purchase that never renews and never expires. No feature is locked behind it, there are no ads, and if you ever lose access every palace you have built stays readable and walkable. HONEST ABOUT THE LIMITS The method of loci is good at ordered lists of discrete things. It will not give you understanding, and two items per locus is the sensible limit. Lociform says so inside the app, and sets out what the research shows alongside where that research is weak.

Verdict
Numery and Lociform are too close to call on the numbers: across 5 compared parameters β price, ads, in-app purchases and device support among them β neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
