ギガと光速が欲しい

変な広告もなく使いやすいのは良いが、無線屋さんにとっては単位系にG(10^9)が無いと使いにくい。また、定数に光速cがあると、波長計算とかが楽なのですが…

No support

Having trouble entering scientific notation numbers into the app with no luck. Tried contacting the creator for support but everything is in Chinese making it impossible.

補助単位 k、m、Mが使えるのが助かります

エンジニアです。

設計計算する際、
補助単位k、m、Mなどをよく使います。

手元の関数電卓も補助単位が入力できるものを使っていましたが、
スマホのアプリの関数電卓にそのような機能がなく不便でした。

このアプリは補助単位が使え、とても重宝します。

工学系エンジニアにはオススメのアプリです!

Piece of junk!

I'm learning about scientific notation in school. We were assigned homework and I was looking forward to a quick finish but still correct answers. The default calculator lacked scientific notation so I got a new one. That calculator lasted 8 minutes on my phone. My opinion; save your time and don't get this. This calculator made no sense. I went to help and found nothing AT ALL on scientific notation. In conclusion, piece of junk! (I gave it a star at all because I couldn't send this without a rating).
