Pros and cons of Compoundee app for iPhone and iPad

Compoundee app good for

A simple and effective interface that allows for the input of almost any variable you would need for simple financial calculations. Known bugs are spelled out on the developers website. Calculations are based on a 30/360 day convention, so calculations become less accurate with shorter compounding periods and/or longer duration. Inflation rate adjustment and bookmark features are a nice touch. An update that addresses the accuracy issue would make this a five star product. Probably one of the best first releases Ive used to date, considering that this seems to be the first and only product from this developer.
I have used this app for a couple of years now. With each release they have added great features. Now if they would onlyget rid of the stick man on the icon. Worth every penny
Does exactly what the momma ordered! This Grandma is saving her money with the help of this app

Some bad moments

Great app! By far the best in its price range. The fact that it is also a great payment calculator (just use the "Deposit" calculation and use "0" as the future value) should be mentioned in the app description.
Great app, just what I needed. Simple, clear, easy to compute any of "the big 5" in the famous annuity equation. Regards, Dave.
I didnt look at this app very well before purchasing it. I thought with the amortization table it would calculated loan payments. It looks nice but what it does is very simplistic and could easily done in an excel spreadsheet. The same can be said of calculatng payments but I wanted something I could do when my computer wasnt available.
For the APY calculation you can not put in deposits and withdrawals just deposits.
I like how you can switch to all different factors: interest/principal/years/etc. This app is great if you are at a stage where you are building wealth & want see different scenarios of how much you can make with compound interest.
When I was young I took a college course on amortization and compound interest etc... We had to use logarithms to work the formulas that this app does.. This app can and will make you a millionaire if you let it
