Crashes constantly

Any number over 10 figures crashes the app and gives error messages.

Thank you for your feedback! This has been fixed in version 1.2.3.

No Support for Decimal Places?

Maybe I’m doing something wrong but it seems like the app only allows for integer values and not float in the calculation. E.g. I’d like to calculate 4.25% vs. 4.5%.

Other wise the interface and options seem nice.

Good, but

Why can’t I start with 0?

Great, but…

Needs to calculate for full decimal places. Only gives returns in 100s (eg 53.2k instead of 53,275).

Thank you very much for the feedback! Inside the app if you long press on some values, it will show you the complete value with decimals. We've improved this in the latest version. Now the PDF will show up to 2 decimals.
