Four pricing models that should not be mixed together
A self-paced course is usually a one-time product with defined access. An adaptive app charges for software that generates or schedules sessions. A marketplace package has terms set by the selected trainer. Dedicated coaching charges a recurring retainer for ongoing human work.
The correct comparison unit is not always “per month.” For a course it may be total program cost; for coaching it may be cost per check-in or week of access; for an app it may be the annual effective price.
