User reviews

良いのですがiPadで横

iPhoneで使う分には良いのですが、iPadで使う場合は横表示に対応して欲しいです。それとoctは必要ないので、ASCII文字の表示ができれば最高です。

デバイスに対応していません

アップデートで対応機種から外されました。まあ前のバージョンが使えるから問題無いが、一括バージョンアップのたびにメッセージが出るのは面倒

入力桁数

HEXで F が30桁も入力できてしまう。

ペースト出来ない

色のセンスがよく、機能も便利に使わせていただいてます。最大が64bitまで桁があるのがいい。ただ、ペーストが出来ないのが不満です。他の電卓の計算結果をペーストできればいいのに。

iPhone5sで活用中。

フルスクリーン表示で使いやすいです。
まあ、普通に。
