The world’s most precise Japanese and Korean app store analysis — powered by our proprietary language engine.
Generic tools split words at spaces — Japanese and Korean don’t use them. Our proprietary morpheme logic and natural-language engine reads every title, keyword and search the way local users write it. Nothing slips through.
It groups kanji, hiragana and katakana spellings into one keyword, splits Korean compound searches into the words people mean, and learns from over 2 million keywords every day.
Get found, then get chosen. ASO Index scores both and shows what to fix first.
Our language engine splits your title, subtitle and keyword field into the words people search — then shows which ones rank and which to add.
