# HIIT vs Voice Pacer

The clearest difference is ratings volume: HIIT at 31K against Voice Pacer's 2. Voice Pacer's advantage is update cadence (every 8 days vs monthly) and rating (5.0 vs 4.8). On price, ads, 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 Voice Pacer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Voice Pacer holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: HIIT has 31K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 91% of HIIT's written reviews are positive against 100% of Voice Pacer's.

HIIT ships an update monthly, Voice Pacer every 8 days. The most recent releases landed on September 24, 2026 and August 23, 2026 respectively.
