# Intervals Pro vs Intervals

The clearest difference is in-app purchases: Intervals at none against Intervals Pro's 8. Intervals also leads on rating (5.0 vs 4.8) and iOS requirement (12.1 vs 17.5). Intervals Pro's advantage is ads (none vs shown) and update cadence (every 8 days vs every 4 months). On price and device support there is nothing between them.

Both are free to download. Intervals Pro sells 8 in-app purchases, starting at $2.99 per month. Intervals asks for nothing beyond the download.

Intervals 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 1, so its average is the more settled of the two.

Intervals Pro ships an update every 8 days, Intervals every 4 months. The most recent releases landed on October 18, 2026 and October 2, 2026 respectively.
