The clearest difference is review sentiment: YAPtraining at 100% against HIIT's 57%. YAPtraining also leads on rating (5.0 vs 4.3) and in-app purchases (none vs 8). HIIT's advantage is update cadence (every 2 weeks vs every 4 months) and ratings volume (34 vs 4). On price, ads and device support there is nothing between them.

Both are free to download. HIIT sells 8 in-app purchases, starting at $0.99 per month. YAPtraining asks for nothing beyond the download.

YAPtraining holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: HIIT has 34 ratings behind it against 4, so its average is the more settled of the two.
