The app is OK (interface could use some work, but it's a good start), but the data doesn't match what is suggested on the website.
For example, Tier 2, week 1 day 1 on the site says 6, 6, 4, 4, 5+. The app says 7, 7, 5, 5, 6+, an additional pushup per round.
I guess the app is just pushing harder to get to fitness? All the same, I'd like it to be consistent.
