iMC (iMortgageCalculator) iMC calculates monthly and bi-weekly mortgage payments when given a property price, interest rate and amortization term for Canada and US mortgages. Originally was written for Canadian calculations, but decided to include results for both Canada and USA. Extremely simple to use and is a perfect companion for real estate shopping and/or mortgage shopping. Works on any iOS device running 3.0 and newer, now including support for retina display.
