Okay, so it's been two years since I published this app. It seems to result in 15,000 downloads per year. I published mostly for students (or someone like me, verifying car lease amount from pure N I PV PMT FV buttons).
Now I am forced to revise this webpage since I see negative feedbacks coming from two sides.
1) People who really does not know the effect of periods per year. This calculator is by default set to monthly calculation. Those that regularly use financial calculator would agree as written in one of the review. This setting can be changed easily. RTFM.
2) The competitions - yes. you want to sell your app. Sorry, this free app beats you. So rethink your button structure - as you can see it's not easy to map the automata correctly. Just drop your hatred and email me, who knows if I'll give you my code?
Even if you know what to do intuitively, still read THE MANUAL to learn about the memory function. It comes in handy at times. Also you want to learn how to review what's stored in TVM buttons.
If you are a student taking Finance 101, following through this CHEAT SHEET will make a good brain exercise.
Coming to the third year, I really asked myself whether to pay another $100 for the developer program. I eventually paid $100 but it was hard to justify after seeing all those negative reviews. Per $1 I can only support 150 students. Hm.. it's not worth it at all. So, if you liked this, leave a mark and write your honest review.
