Any SaaS doing daily subscription, in addition to monthly/annual?

It might be nice as a consumer, but I don't think I've seen anyone doing daily. Perhaps the flat rate on the credit card transaction is prohibitive.

I don't think going from monthly to daily subscriptions really benefits the business in a meaningful way.

I've seen some personal apps, like the major dating apps, offer weekly subscriptions but at a much higher rate vs a prorated month.
