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.

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.

It’s like an old friend

I learned to do loans on this calculator when I first started in the mortgage industry. I was very happy to see this as an available app. Easy to use, quick reference to check on how to’s with the help function. Worth every penny.
