Side by Side


About TriLoan

My name is John Coogan. I'm a programmer in central Virginia.  In 2000 I began looking into purchasing investment property.  I found myself constantly creating mortgage calculators in spreadsheets, and then copy-n-pasting them for multiple side-by-side viewing.  I wanted this side-by-side mortgage calculator convenience in my pocket.  Those were the days of PalmOS devices.  So I embraced the learning curve and completed TriLoan for PalmOS in 2001.

TriLoan grew rapidly to over 6,000 customers and over 30,000 downloads.  But the days of PalmOS devices became numbered due to the advent of phones with build-in browsers.  PalmOS devices gradually fell out of use, but I managed to keep mine working until 2014.  Then when my last Palm device finally died.  I was back to spreadsheets and missed the convenience of TriLoan.  So finally in 2020 TriLoan is back up an running for Android.  TriLoan for iOS is coming soon.

Stay Tuned.
