I would love to use Zwift - but $14.99 to use it 2-4 times/month is rediculous. If you offered a plan with a lower monthly rate but limited # of uses - or offered a plan that was $2 per ride - I think you would find that more people like me would pay you more money.
It might be worth looking at other training platforms and comparing costs. I suspect they’re all largely in the same ballpark?
Or switch to one of the free apps.
Every paid platform has the same entry level cost - which pushes you to the free platforms. Capitizing on areas where no one has any offerings raises capital.
