Japanese,
The key is kanji.

“I've tried many apps for memorizing Japanese words, even paid ones, but iroiro feels like the all-in-one version. The short-term and long-term memory review system is super useful, and the kanji mnemonics are truly the best. Being able to learn kanji alongside vocabulary with radical decomposition illustrations makes it so much more effective.”

“The biggest advantage is that the content is verified, so I can study with confidence. When using Anki, the lack of explanations made it hard to remember, but the detailed kanji explanations here make it much more approachable.”

“I've tried several other apps, but none were as clearly organized from hiragana to each JLPT level as this one. As a working professional, I appreciate being able to study during short commute breaks. Other apps rely on simple repetition and I'd quickly forget, but the mnemonic system really helps kanji stick in my memory.”

“Been past hiragana and katakana for ages but kanji just wouldn't stick? Download this app right now. Other JLPT apps are just infinite repetition leading to infinite forgetting. iroiro's mnemonic helper makes kanji memorization actually work! Personally, I think this is the best JLPT app out there.”

“The clearly curated content structure, memory-aiding images, detailed radical explanations, and FSRS-based review scheduling allow for incredibly deep, high-quality learning in a single app. Highly recommend this vocabulary app to anyone preparing for the JLPT.”

“I've spent so much money on Japanese tutoring, paid apps, and academies, but this app is great! The design is cute and not rigid, which makes me use it more often. Having example sentences included is wonderful! Going to pass the JLPT with this!”
