# Interval Flow vs Voice Pacer

The clearest difference is review sentiment: Voice Pacer at 100% against Interval Flow's 48%. Voice Pacer also leads on monetization model (free with in-app purchases vs subscription) and rating (5.0 vs 4.7). Interval Flow's advantage is ads (none vs shown) and ratings volume (168 vs 2). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Interval Flow sells 10 in-app purchases, starting at $4.99 per 3 months and Voice Pacer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
