Starting the onboarding with a paywall

Curio goes against the traditional smooth onboarding trend and displays a paywall as the very first interaction with users. If you don't pay attention, you could think that there is no free version. However, you can select "Want a preview? Take a look" to access the free version and enjoy 10 stories for free. The psychological rationale behind is interesting: the user feels lucky to get into a premium product and are aware that there is no way to use Curio in freemium mode.

Sweat prevents users from using any feature of the app if they do not pay for a subscription.
