User reviews

Was looking for an RPN calculator for my new Watch4 and found this.. it's not RPN, but I really like it for this form-factor. Small request, adding constants like pi would be nice... polar to rectangular would be awesome!

What an excellent app. Apparently so simple to use but the development behind it is brilliant and voice activated as well, great.

Really handy and a must have app! I can confirm it works well with Samsung Galaxy Watch4 Classic (Wear OS 3) 👍
