Easier to have on my phone than have my calculator on me all the time! Update: After using the app for a few weeks I decided to pay for the pro version just because it is so convenient. Since I just started accounting classes I am still getting to know the calculator and I find if I get something wrong, it's my error and YouTube videos help a lot when learning how to use the calculator. I highly recommend this app, works great for me so far.

After guidance from Angel (the app developer), loving the app!! The below discrepancy is resolved. I want to like this app, but it does not work accurately on my Google Pixel 9. I was trying to do a simple FV calc using the five keys on the app but it produces a different result. Actual HP result for ... N=5, I=.75, PV=0, and payment =-50. result 148,192. same amounts and key strokes in this app results in 147,089. Any advice?

Hi Ken,
Please make sure you are using a consistent framework for both calculators. There are more factors to TVM such as period mode (END vs BGN), periods per year (P/Y), compounding per year (C/Y), etc.

BA Calc is perfect for using in personal finance in addition to basic calculation stuff. It's very useful for those who don't have a physical finance calculator. Five-star rating for the dev out here.
