Apple does not offer trials for paid upfront apps but they do offer trials for subscriptions. Also I’ve seen developers do things like X searches for free (either one time or per month/week/day) then you have to subscribe or pay a one-time unlock fee. CallSheet (an IMDB replacement) does this and it’s nice to be able to try out the app a few times before you decide if it’s worth the $12/yr or whatever it costs.
