Dipsea

Too few options under the truly, 100% free umbrella to get any sort of real feel for the app. Also, Dipsea is losing sales by requiring a card number for a "free" trial as that is a large red flag for many people (those of us who do not like to give our credit card info out for a free trial that, when over, you can never seem to cancel). A free trial should be a no strings attached deal because they truly believe in what they are selling; any apps that dont offer this get the big skip by yours truly.
