Me and a friend are working on a mobile app, and we'd like to give the user an amazing one-time deal, and play a tutorial at the start of the app. The thing is, we want it to only appear at the first launch of the app, not the second, or third, etc...
(I have tried LocalStorage by checking for the item "FirstTimeStartup" after the logo animation, and from there go to the deal layout or the regular layout depending on whether the "FirstTimeStartup" value was found. I couldn't get that to work.)
Is there a much easier way to do something like this? I feel like there is a much simpler way that went straight over my head.
