I've actually been looking for a good feedback solution for a while. I like the look of the app a lot, and I'll try it out in the wild soon. The one thing I find weird about it is "Just $12 / month or less". Normally apps give price floors, not ceilings. Was there any reason for this?
Also, who is your target audience here, nationally speaking? I saw "$12,00" on the signup page. If this is aimed toward US customers, it should be $12.00, not $12,00.
