It really depends on what you are attempting to accomplish. Trigger Happy (from my assumption since I don’t have it installed) is that you can have a variety things happen when you trigger something (i.e. a virtual switch).
For me, I have a set of routines that I want to trigger on a normal basis. These routines lock the doors, turn off lights, set the mode, turn on the alarm, etc. Another app could do that…the routines are just built in so that works well for me. That is the beauty of community built apps…they serve a purpose for some folks, and someone else will come up with another app to appeal to someone else.
However, to give my app a shameless plug, I am not sure Trigger Happy can set the thermostat to a specific temp like mine can 
(newest version just posted this weekend). All joking aside, I make no money by creating my apps so there is actually no incentive to do it outside of the love of HA.
