# Intervals Pro vs Interval Timer

The clearest difference is ads: Intervals Pro at none against Interval Timer's shown. Intervals Pro also leads on ratings volume (14K vs 379) and update cadence (every 8 days vs monthly). Interval Timer's advantage is review sentiment (97% vs 84%) and iOS requirement (15.0 vs 17.5). On price, rating, 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 Interval Timer sells 12 in-app purchases, starting at $2.09 per month. Whichever you choose, the download price is not the number that matters.
