I don't know about trigger traps or time lapses but iOS 10 is suppose to allow apps. to save RAWs from the iPhone.
I use the regular camera app. to make time-lapse movies, works fine especially with OIS on my 6S Plus.
Tried using the time lapse functionality on my Nikon DSLR but didn't work that well. First I would need to set up a tripod and second, it would take hours and hours to produce say 30 seconds or more.
Maybe some of the 3rd party apps. developers will update their apps, including those for taking interval photos, after iOS 10 comes out this fall.
