Read the other reviews and took note of it for when I try the app. Not sure what the issue is for the other users or maybe its a problem with their phone/tablet using the app, but I had no issues using this on my iPhone. It had all my stored payment information which allowed me to pay for my rent using my bank account (no fee!!!) instead of my debit card. Ive been paying my rent like this for about a year and a half now with no issues. Perhaps the programmers fixed the bugs prior to me using it, but I literally paid my rent in less than 15 seconds with this app. I took a screenshot too that shows the name of my complex, my unit number, the amount paid, and the reference number for my transaction as a "receipt".
