I had the free version and it kept prompting me for upgrade. So I ended up paying for it but thats when things got horrible. First I could not find a lot information on how to mark your payment as extra principle. There was a button, but no further explanation. I also entered one debt wrong and had no choice of correcting so I had to remove the app from my phone and reinstall. Well, now I am back to the free version and lost my $2.00. Horrible app. DO NOT PURCHASE!!!
