Calculator Advanced

I got this app primarily to use my own function that I set up in the app. That part of this calculator is glitchy to the point of being unusable. My function required values of 8 variables to be input. Once I had the function set up (which itself was a chore with this app), I went to use it on my iPhone 23 pro. Well, I could only input values for 4 of the variables while the rest remained somewhere in the lower part of the screen where there was no way to even see them. I deleted the app, downloaded again and repeated the process with the same result. So, in short, this app did not serve me at all.

Minimalist great functioning app with customization capability,fills the need perfectly for quick calculations in everyday life, and then some…

It adds an unwanted item in the predictive bar which persists in text messages and other places when the keyboard is used. It will not go away, even after deleting the app.

The core functionality to easily create formulas and then run them repeatedly is great. A spreadsheet app (Numbers, Sheets, Excel) can provide similar functionality, but with a more cumbersome interface. UI anomalies: • Long value prompts prevent the input box from appearing (eg the Gravitational force formula in Physics won’t enable input on iPhone 13 Pro). • When editing a formula the automatic variable/function recognition jumps the cursor unexpectedly to the end of the text (eg erasing the variable name “distance” in the middle of a formula will cause the cursor to leap to the end when the automatic function detector sees “distan” and interprets tan as the tan() function. • inputting the numbers at the bottom of the screen and then seeing the result at the top is a bit strange. Normally UIs flow from the top down.

The developer took the time to respond so I gave them 2 more stars for answering. Maybe I missed it, but there is no "CLEAR" button to erase everything after I have done my calculation. Sorry, better calculators out there. This one has some nice features but without an easy way to erase everything, not worth keeping. Deleting it now. Also, why have all the numbers and operatives at the bottom of the screen and the = sign at the top?? It almost seems like an after thought when programming- "Oh, we need to be able to solve the problem, so let's put the = sign somewhere, but not in a good spot".
