Meow Linguistics — Interpret your cat's meow with academic citations on board. Tired of guessing what your cat is saying? Meow Linguistics doesn't lean on AI mysticism. Instead it applies three historically grounded research models so every conversation with your cat has a paper to fall back on. 【Why Meow Linguistics】 ▸ Academic, not anecdotal We don't invent cat language. We cite it. Every translation traces back to a peer-reviewed source you can read for yourself. ▸ Three independent schools, switchable on the fly (Phase 1: Moelk drives translation; all three appear as intro cards) - Moelk 1944: The American Journal of Psychology's classic 16-phoneme phonetic study of the house cat. - Meowsic 2019: Lund University's modern prosodic analysis — emotion read from F0 contour. - Marvin Clark 1895: 17 cat words from a Victorian-era public-domain dictionary. ▸ Completely free in Phase 1 No in-app purchases. No ads. No third-party tracking. Download and use. ▸ Translation happens on your phone All logic runs on-device. No network. No cloud. Type a phrase, tap translate, get a Moelk phoneme + emotion label + a pre-recorded cat sound. Your history stays on your device. 【How to use】 1. Type what you want to say to your cat in Chinese or English (e.g. "good", "I'm hungry", "no"). 2. Tap translate. 3. See the matching Moelk phoneme + emotion + pre-recorded cat audio. 4. Tap play to let your cat hear it (or to learn it yourself). 【Supported schools】 ▸ Moelk Classic 1944 (Phase 1 default translation engine) - Source: Moelk, M. (1944). Vocalizing in the House-Cat: A Phonetic and Functional Study. The American Journal of Psychology, 57(2), 184–205. - Online: JSTOR 1416947 (link inside the in-app About page). ▸ Meowsic Prosody 2019 (intro card; engine ships Phase 2) - Source: Schötz, S., van de Weijer, J., & Eklund, R. (2019). Phonetic Methods in Cat Vocalisation Studies. Zenodo. - DOI: 10.5281/zenodo.3245999 ▸ Victorian Clark 1895 (intro card; public domain) - Source: Clark, M. R. (1895). P***y and Her Language. Public domain. - Hosted on the messybeast online library. 【Legal disclaimer】 ▸ Interpretive, not authoritative This app provides an interpretation of academic research, not a literal translation. Cats vary enormously between individuals — results are best-effort guidance, never authoritative conclusions. ▸ Not a substitute for a veterinarian Do not make medical, behavioral, or veterinary decisions based on this app's output. If your cat shows abnormal signs (refusing food, hiding, excessive meowing), consult a qualified veterinarian. ▸ We do not collect your personal data This app does not collect your name, contact details, or location. All translation history stays on your device. 【Need help?】 ▸ Email us: jay801224@gmail.com ▸ Privacy Policy: https://jay801224.github.io/game-legal-pages/meowlinguistics/ ▸ Terms of Service: https://jay801224.github.io/game-legal-pages/meowlinguistics/terms.html ▸ Support: https://jay801224.github.io/game-legal-pages/meowlinguistics/support.html 【Phase 2+ roadmap】 ▸ Premium subscription: cross-school Ensemble model returning a confidence score per meow. ▸ Two-way translation: record a cat sound, get text back. ▸ More animals: dogs, birds, rabbits (Phase 3). — Thank you for giving your cat a paper to fall back on.

Verdict
The clearest difference is in-app purchases: Meow Linguistics at none against 課咖ClassKey's 2. Meow Linguistics also leads on ads (none vs shown). 課咖ClassKey's advantage is update cadence (every 2 weeks vs every 5 weeks). On price, device support and iOS requirement there is nothing between them.
