The suggestion “seek alternatives” is a cop-out. Keep the pressure on, they can contact JEfit and apply pressure.

JEFit, unlike Exist, has no way to programmatically access user data. We can’t change this, we cannot do this work for them. If you want to apply pressure, your efforts would have more impact if you contacted them and asked them to make this possible for you, their user, so that you can continue using JEFit rather than finding an alternative. Hearing this directly from their users would be more persuasive to them.
