Ever since the pandemic, it's been pretty hard to gauge wait times. Even though some rides are close to full capacity, they're not putting 2 different parties in the same row, so that still slows it down, and with everyone having different parties, it's hard to say. Find most times are generally inflated.
I was at MK and Epcot on Sunday, and on HM it said 25 min wait, it was barely 5. On Soarin , it said 25 as well, and it was roughly 5-10. All the waiting I had was just for the preshow movie to begin.
TImes I went on MMRR, I found it to be 10-15 min less than advertised time.
But I guess to answer the question, the times you see on the app are the times you'll see posted on the ride itself.
