HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (145 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

私には合わなかった

打合せで使用しました。口コミの評判が良さそうでしたので、まずは1人で試してみて、使えそうかなと判断しました。その後、実際に打合せで利用しましたが、話してもいない「ねずみ」の話を話し出しびっくりでした。ビジネスでは、まだ怖くて使用できないかな。

★★★★★Oct 14, 2026
最高！

英会話の練習に使ってますが、とても良い学習方法になってます！

直ぐに無料の枠が終わる 同時通訳できてよとても良いが、料金が高いなー

★★★★★Oct 4, 2026
翻訳そのものは使える

日本語↔︎中国語の通訳で使用。 翻訳機能そのものは使えるけど、スピーカーの音量はなぜ3段階でしか設定できないのか？ 音量を最低にしても大きすぎる場面があるので無段階で設定できるようにして欲しい。
