Willet payments (http://getwillet.com http://getwillet.com ) is a similar product but has what I believe a better integration process and lower barriers to entry for both buyers and sellers. Willet supports in-app payments for one time purchases, subscriptions and repeatable purchases. (Full disclosure: I am a co-founder of Willet )
