Anyone should be able to view it, even without an Apple account: https://apps.apple.com/us/app/three-cells-your-life-system/i... (bottom right):
> Three Cells Weekly $2.99
> Lifetime Access to Three Cells $29.99
> Three Cells Weekly $2.99
The ratio here feels a bit off, $155.48/y or $29.99 for life screams "trying to push you to pay a lot for an app I know you won't stick with" rather than "we've got great value options for any type of user". There is a 7 day trial as well, so even more confusing as to which kind of user is supposed to want the weekly payment.
