# i vs Workout Timer Interval & HIIT

The clearest difference is rating: i at 5.0 against Workout Timer Interval & HIIT's 4.5. i also leads on iOS requirement (13.6 vs 16.1). Workout Timer Interval & HIIT's advantage is ads (none vs shown) and ratings volume (145 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. i sells 1 one-off in-app purchase and Workout Timer Interval & HIIT sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

i holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Workout Timer Interval & HIIT has 145 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 43% of i's written reviews are positive against 53% of Workout Timer Interval & HIIT's, so the app with the better star average is not the one people write more warmly about.

i ships an update every 9 days, Workout Timer Interval & HIIT fortnightly. The most recent releases landed on August 20, 2026 and September 21, 2026 respectively.
