Verdict
The clearest difference is ads: Interval timer at none against HIIT's shown. Interval timer also leads on update cadence (daily vs monthly) and iOS requirement (14.0 vs 16.0). HIIT's advantage is ratings volume (31K vs 37). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. HIIT sells 11 in-app purchases, starting at $2.99 per 7 days and Interval timer sells 3 in-app purchases, starting at $2.49 per 7 days. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for HIIT against 4.8 for Interval timer. That said, the two scores are not equally well evidenced: HIIT has 31K ratings behind it against 37, so its average is the more settled of the two.
