BA Finance Plus 4+

Best BA Financial calculator

I have not used my TI BA Financial calculator for over 30 years, and I can’t find the calculator manual. Recently I have a need to calculate IRR to compare different annuity products. Before I came across this app, I tried a few other financial calculator emulators and was frustrated with the instructions. This includes the TI user manual. Needless to say I lost confidence in the results those apps yield.
This app outshines all other emulator apps in several ways.
1) it’s built in manual with sample problems clearly shows you how to enter each key to come up with the right answer.
2) it explains the concept behind the calculator. Things like work sheet and time value of money.
3) it’s enhanced keys will show additional info to clarify the parameter you are using. The most useful one is is periods per year (P/Y). If you are working on mortgage, most likely you are working on monthly payment, so you need to set P/Y to 12. Once set, the P/Y key shows 12 on it. Clever design!
4) print worksheet will print the parameters of the worksheet you are working on to tape, and you can view the tape to trace back your key strokes.

HIGHLY RECOMMENDED cause you can learn or refresh quickly how to use this wonderful app.

Excellent app / great value

I use it many times a day. So nice not having to carry a separate - more expensive - calculator. Easily shared across devices.
My update as of Sept 2017- have used it for more than a year. Still one of the best apps I have. 5+ stars!
My update as of August 2018: still nothing better. still use it daily. great for professionals. However, everyone over the age of 15 should have it and know how to use it for both loans and investments/retirement projections.
As of September 2019, still my go-to finance app - daily - if not several times a day.
I don’t know if Apple allows it, but the developer should have a means of being compensated - even voluntarily by the user. I would happily pay a modest monthly or annual fee as long as I continue to use it. It IS that good!!

It doesn't work in IPads

Since last version, it doesn't work in IPads.

After the developer's response, I changed my review to five stars, thanks to the developer's customer service. However, either because of Apple's fault or because of the developer, I do not understand how a hardware that works well should have these difficulties because it is old. This is the first time in an application update that it is incompatible with the IOS version of the IPad. Finally, I do not think it's sustainable for the planet to turn a functional IPad into future "junk".

Developer Response ,

Version 4.5 of BA Finance Plus has been tested and runs properly on all iPads that have iOS11 installed.

Your iPad is running iOS 9.5.3 which is not compatible. Apple no longer supports your model of iPad (generation 3) with iOS updates so you cannot update your iPad to the latest operating system. However, if you purchased a previous version of BA Finance Plus, you can download it by running the AppStore app, touch the Purchased tab, find BA Finance Plus in the list of your purchased apps and download it. The AppStore will download a previous version that is compatible with your operating system.

Instead of leaving a bad review why don't you consider directly contacting the developer who will be more than happy to assist you to correct the problem? Touch the ? key twice then touch the "Contact tech support" button.
