小学生でも使えるRPN計算機
大変使いやすいRPN計算機で、小学生の子供も、１度使ったら、この計算機以外は使いたがらないようです。
やり方がわかっていないのかもですが、iPhone, iPadで使用しているときに、スワイプ入力などで、”一つ前の計算に戻る・取り消し”処理が行えないのが残念です。

RPN計算機の中で一番のおすすめ
表示がシンプルで見やすいです。RPN操作に必要最小限のボタンが用意されていて、使いやすいです。それでいて「科学計算」モードに切り替えると、多数の関数が使えるようになります。さらには、プログラミング電卓の機能もあります。RPN計算機アプリは多数試しましたが、これが一番良いです。「カッコが使えない」という他の方の評価がありますが、RPN計算機に対してそれは褒め言葉だと思います。
Almost perfect
This is by far the best Apple Watch calculator app, period.
Unfortunately there seems to be a bug where the programs you create on the iPhone do not sync to the watch.
Even with this bug, this is still well worth buying over the Lite version of this app.

Functional, but UX desperately needs work on WatchOS
Functionally, this is a pretty competent RPN calculator. The design isn't trying to directly copy an old HP interface and it's the better for it. On iOS, that's essentially the end of the story. It works.
On WatchOS, the user interface design has a number of major inconsistencies with standard UI patterns:
The watch app is organized as a single screen with two trays at the top and bottom. The trays are accessed exclusively via touch. The stack is in the top tray and advanced functions are in the bottom tray. This is quite different from most software for the Watch, which generally use sliding cards to access things which don't fit on one screen.
The lower tray, sensibly enough, is accessed by swiping upwards anywhere on the bottom edge of the display and dismissed by swiping downwards.
The upper tray, on the other hand, is accessed by swiping down from the right half of the top edge of the display. There does not appear to be any function assigned to the left half of the display. The tray is dismissed by swiping upwards, but a full row of space in the stack is dedicated to a large "back" button which duplicates this for no discernible reason.
This arrangement simply isn't very good. Every Watch includes a hardware control for vertical movement and it's not used in any way despite the use of vertical movement for navigation. The touch controls are implemented strangely. The end result feels very non-native, is fiddly to use, and generally lacks polish.

Great calculator!
This is a great RPN calculator. I use it regularly on my Mac.
Please update the Mac app so that it saves the *size* of the window. I have to make it larger every time I open the app.
