# Intervals Pro vs Voice Pacer

The clearest difference is ads: Intervals Pro at none against Voice Pacer's shown. Intervals Pro also leads on ratings volume (14K vs 2). Voice Pacer's advantage is review sentiment (100% vs 84%) and rating (5.0 vs 4.8). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Intervals Pro sells 8 in-app purchases, starting at $2.99 per month 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: Intervals Pro has 14K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 84% of Intervals Pro's written reviews are positive against 100% of Voice Pacer's.

Both ship on a similar rhythm, roughly every 8 days. The most recent releases landed on September 26, 2026 and August 23, 2026 respectively.
