ModNote: Merged thread for discussion of implementing trial versions or trial periods or any other "try before you buy" scheme for iPhone/iPod apps sold through the App Store. Please discuss all of that here, including yay, nay, how long is too long, how short is too short, etc. Thank you! On other smartphones most applications are available with a short-term trial period (either a number of days or number of application launches) so you can see if it is worth spending $$ on. Does anybody know if this is possible through the app store? I'm afraid to click the "buy it" button for fear of committing myself.
