Great question, there is no difference really!
What happened is that when we first launched the GymStreak app, there was an early adopter life-time plan which was called the "Forever Plan". However a couple of month after the launch we switched to monthly and annual subscriptions. There is no difference between GymStreak Plan and GymStreak Premium.
