# Tabata Timer vs HIIT Interval Timer | Cero

The clearest difference is review sentiment: HIIT Interval Timer | Cero at 75% against Tabata Timer's 38%. HIIT Interval Timer | Cero also leads on ratings volume (435 vs 6) and update cadence (every 3 days vs every 10 days). Tabata Timer's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Tabata Timer sells 2 one-off in-app purchases and HIIT Interval Timer | Cero sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: HIIT Interval Timer | Cero has 435 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 38% of Tabata Timer's written reviews are positive against 75% of HIIT Interval Timer | Cero's, so the app with the better star average is not the one people write more warmly about.

Tabata Timer ships an update every 10 days, HIIT Interval Timer | Cero every 3 days. The most recent releases landed on August 15, 2026 and September 29, 2026 respectively.
