★★★★☆ I love this app but I have one critique
This is gunna be quite helpful for me but I do ask that you add English translations to the words! Like if you tap a word, a definition will pop up or something. That would be 10x more helpful to expand my vocabulary. Thank you.…
★★★★☆ English translation
It would be nice if there was English translation so I can practice the words, no romanization needed.…

★★☆☆☆ No sound!!!!!!!!!!!!

★★★☆☆ Audio only with earphones
You have to use earphones to listen, otherwise there’s no audio. It’s rather inconvenient.…

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
