Simple and consistent
The app has been reliable, it simple and the use is consistent. The developer has continued to maintains their app for years. Which is great
Missed Opportunity
This could be a good app if it offered NPV (Net Present Value), SIR (Savings to Investment Ratio) and AIRR (Adjusted Internal Rate of Return) calculations. As is, it's not worth $0.99; with the above calculations added, it would be worth $1.99.
