Einfach, schnell, unkompliziert
"Echt brauchbare und nützliche App. Macht was sie soll, funktioniert wunderbar und ist fast unsichtbar. Perfekt"
Simple app. Look beautiful. Works great.
"It’s literally what it says. Doesn’t try to pack 50 different features into a the small simple menu bar app. Keyboard shortcut makes it super easy to access. The themes are nice. One request: please allow different sizes for the calculator. I actually find the numbers to be very big and it feels like using a calculator made for older people with bad eyes. I understand many people might like the size so an ability to choose different sizes would be nice."
Perfetta!
"Ottima alternativa alla calcolatrice di sistema che tenevo sul dock. Averla nella barra in alto, mi fa recuperare spazio per altre icone. Bella, funzionale e utile."
Bien conçu !
"Numsy is really pleasant."
Excepcional
"Hasta el momento nunca me ha fallado."
操作感が良く、かわいい
"数字をキーボード入力できるのが良く、タップ音や入力音が出るのもかわいいです！ 割合計算を数式ではなくジェネレーターで計算できるのも珍しくて、地味に良さそうです。 ただ、ウィンドウをポップアップすると、消せなくなった（消せるボタンがあるのかもしれませんが、見切れているのか表示されない）ので、そこだけ直してほしいです。 あとは数字をコピペで入力できるようになるとより良いです。"
