5/5Versatile
Easy to use, good mix of conversations. One missing conversion that would be useful is between DMS and D.D for geographic data (I don’t know why apps even use DMS, but they do).

3/5No RPN
Average - most calculators these days are essentially generic. The functions are available for all and if you’re going to charge $7.99 it’s important that you add something unusual and that you keep a running explanation of your functions. I find RPN to be so the I look for that and thought I saw it here. My bad. This is not well produced - it’s “10 functions” are not helpful - it does a lot of stuff but hard to find the list. I’m disappointed that I spent $7.99 as I should have known I could have gotten these functions for free. And I Didn’t get what I wanted which was RPN. Not bad but if you charge these days, it should be great. Thanks

4/5Impossible to Update for Currency Values
I have enjoyed this app for years, until last week when I couldn’t get the date to reflect the current date. Today I went to the App Store and decided perhaps I needed to purchase a new version of the app .$7.99 vs what I believe was previously Free! Only to receive the exact same notice , “unable to connect” ... while I am connected to the Internet! Wi-Fi on my Apple XR. Now I’d like my Apple charge refunded ! Ever hopeful someone will contact me! precious Auntie
