Does let you make extra payments. Great app that is hard to find. I searched many mortgage amortization calculator apps and none allowed you to make extra payments.
Good, but.. I have the same app on both: phone & tablet, but for some reason the % of loan payed is different on each even though the loan info is the same.
Does not let you make extra payments. Lots of ads.
Added support for qHD screens and interest free loans.
