Units editor broken
There doesn't seem to be a way to add additional unit conversions and when editing an existing, even just changing the name, it resolves to zero. The only way to fix it is to reset all units to default. That being said most of the units one would need are there. It would be nice if there was also a fuel economy conversion, but I created my own using the solver.
Outstanding
Just love this one. Looks like my physical unit. His work on these calculator apps is just a work of art. Such fine attention to detail. Im a financial advisor and this is one of the best financial calculator apps in the store. I think i own pretty much all the calculator apps he has made.
Doesn’t Show as Installed
Great for TVM calculations. The app doesn’t show up in the list of installed apps on the main settings window. Makes me wonder if the app can be trusted. As much as I like the app I have uninstalled it. Hopefully it is really fully uninstalled.
Input Missing Sum
I downloaded and installed this HP-17b emulator on my iPhone and uninstalled it a few minutes later when I tried to use the INPUT key to create a running total and sum and found there was no sum capability. I didn’t try it any further.
Questions
1. Is 17BII+ pro app no long supported? 2. How does the latter differ from this new version? 3. Is there an upgrade discount? 4. Why is there no support page for questions like these?
RLM-17BX
Nice calculator. I had an issue with saving equations in the solver menu. I found that if I touched the save button in the area of its upper left corner, I could save the equation. A touch anywhere else on the button had no response. Other than that, all other options, menus, and worksheets function normally.
Solver Equation Editor is Problematic
The solver equation editor needs a lot of work. It doesn’t always save formulas. In some cases it’s impossible to get back to the calculator’s home screen without erasing all in-progress work. All these things were supposedly fixed in V3.0, but, in V3.1, things are still buggy. This would be a great app if the solver function worked properly. As-is, it’s not worth the $9.99 lifetime price.
Now you can listen music while using the calculator.
