Have been using this over a year, paid the premium one-time fee. Now that the developers have gotten some good reviews, they have changed fee structure to a much more expensive annual fee, along with ads and “premium content” (which doesn’t seem to be as good as free Nike training app or FitOn). I keep getting messages that I must be a premium member to get unlimited saves of my own programs, despite having paid for that already when WorkoutTimer was new - ie in order for this to be good business, the developers should be grandfathering in those who already paid for WorkoutTimer . Im not looking for any new material, just what was offered for the price I paid for when I initially purchased WorkoutTimer at the one-time premium fee. This is what makes users look elsewhere.
