[Learning Records] Supported learning records stay on the device and can be reviewed in the learning report. Some games award local stars for visual progress. [Ads and Internet Access] This free app displays contextual ads in internal learning and game content. Every ad request uses conservative child-directed treatment and a maximum G content rating for younger learners as well as adults. The app does not use personalized or interest-based ads, remarketing, or tracking that links activity with other companies' apps or websites. It does not request ATT permission or use IDFA. For ad delivery and measurement, and to prevent invalid traffic and fraud, the advertising provider may process IP-derived coarse location, app and ad interactions, diagnostics, and applicable device or other identifiers. Internet is required for first-time setup and security verification. After setup, offline access to the ad-free launch screen and top-level main menu depends on the deviceβs saved security status. Internal learning and game content requires an internet connection for genuine-app and security checks, protected-content delivery, and ad delivery. Internal content is unavailable when network or ad delivery is blocked. [Privacy and Optional Permissions] The app does not ask for a date of birth or age range. Everyone receives the same child-protective advertising settings. General external links open after a parental check; the privacy policy is directly accessible. Previous local age-category records are removed when the app starts. Microphone and speech-recognition access is requested only when the learner starts speaking practice or voice input in word games such as word chains and quizzes. Supported speech recognition must run on-device; otherwise the activity does not start. Add-only Photos access is used only when the learner chooses to save a created image. The app does not require an account or login. It does not request contacts, a phone number, or precise location.

PairLingo
Read full descriptionHide full description
PairLingo isn't a template flashcard app β it's built to learn any language pair, at your own pace, with your own words. What actually sets it apart: FOUR WAYS TO PRACTISE Match words in two columns, type the translation from memory, hear a word and type what you understood, or flip flashcards and rate yourself. Matching trains recognition, typing and listening train recall, and cards let you grade each word on a four-step scale β which is what lets the review schedule tell "barely knew it" apart from "knew it instantly". TRULY ANY LANGUAGE PAIR Not just English-Hungarian. Combine any two languages β Spanish-Japanese, German-Russian, whatever you're learning. Pick from 24 curated languages for manual entry, or import a CSV for virtually unlimited language combinations. SMART CSV IMPORT, NOT JUST "UPLOAD" Most similar apps just read the file. PairLingo detects when a word's translation changed (typo fix), warns you about accidentally-duplicated groups with similar names, and lets you decide row by row how to resolve conflicts β update the existing word, or add it as new. PHOTO IMPORT, NO TYPING NEEDED See a word list in a textbook? Just take a photo. PairLingo recognizes the words and groups straight from the picture β entirely on your device, nothing ever uploaded β and shows you exactly what it found before anything's added, so you can fix any mistake first. REAL PRIVACY, NOT JUST A PROMISE No backend server. No account required. No ads, no tracking code. Your words sync across your own devices through your own iCloud account β the developer has no technical way to access your data, even if they wanted to. REAL SPACED REPETITION Not a fixed "wrong answers" bin β PairLingo calculates its own review schedule per word. Words you know well come back less often; tricky ones return sooner. Tap any card to hear it read aloud in its native pronunciation, too. A GENUINELY MULTILINGUAL INTERFACE Not just the content β the app's own interface is available in 6 languages (English, Hungarian, German, Spanish, French, Italian), switchable instantly with no relaunch. IPHONE, IPAD AND MAC One app for all your Apple devices. On iPad, the topics and review rows flow into a grid that fills the wide screen; on the Mac, a native app brings a window toolbar, a full menu bar with keyboard shortcuts and a Settings window. Your words and progress stay in sync between all of them through your own iCloud account. MORE FEATURES β’ A friendly little spider mascot who celebrates your flawless rounds and cheers you on after a slip β’ Optional example sentences on any word, shown once you've seen the answer β write your own, or import them via CSV β’ Manual word entry, group management (edit, delete, rename, merge) β’ Optional daily reminder, at a time you choose β a local notification, no server involved β’ Choose your round size (4β10 words) and which direction to be asked in β’ Stats: daily practice streak, a seven-day practice chart, per-group accuracy β’ 6 clean, matte color themes β’ Built-in help β’ Ready-made starter word lists at all 6 CEFR levels (A1βC2), for English or Hungarian paired with Spanish, German, Portuguese, or Italian β import any level, any pair, anytime PairLingo is built by an independent developer with an original codebase β not a purchased template.

Verdict
The clearest difference is ads: PairLingo at none against Teacher Moon's shown. Teacher Moon's advantage is update cadence (every 3 days vs weekly) and iOS requirement (15.5 vs 17.0). On price, in-app purchases and device support there is nothing between them.
