I can't find the app anywhere. Zeapon is a ghost company, so you can't meaningfully communicate with them. No, you can't do everything the app does with buttons. Okay let me see how you make a time lapse without an app. I left a question here which of course was ignored. They don't want my money so I'm giving it back for something that works. This slider turned out to be pretty flimsy, so it wobbled everywhere. You need some kind of stabilization.
