Incroyable

Magique

Great app, must have for all readers

I love this app! Makes reading complex documents that much easier. 10/10

Wow !

Super App ! Très utile et facile à utiliser

単語ひとつずつ調べる時に便利です。

英語の小説を読んでみようと思って購入しました。
大体の単語は何秒かで意味が表示され、さらっと使うのにとても便利です。
ただ、anteroom (前室)意味が出ませんでした。古くさい単語は出ないことがあるのかもしれません。(ダウンロードすると表示されたりする場合、教えていただけるとありがたいです。)
機能としては、アプリの中心に◯が表示され、カメラ機能でうつった画像の単語と画面の中心にある◯が重なった時に意味と15例ほど例文?などが出てきます。
丸は動かせないようなので、グーグルグラスとかで使えるととても便利そうです。
私は大きなタブレットで使用したのですが、難しかったです。イメージ画像のように携帯での使用が良いようです。
個人的な希望として、指で複数の単語も選択して意味がわかるとありがたいと感じました。
また、表示された意味を選択してブラウザ検索もできたらいいなと思いました。(表示されたものは選択できないため、意味がわからなかった時にコピーして、検索したいです)
それから、用例の中にある検索された単語は色付きで表示されたりしたら便利だと思います。

Brillant, facile d’usage

Très bien fait, un outil simple et utile à avoir. Parfait pour mes lectures techniques. Je vais aussi pouvoir l’utiliser pour voyager et traduire au besoin!
