# Intervals Pro vs Python PTS

The clearest difference is monetization model: Python PTS at free against Intervals Pro's free with in-app purchases. Python PTS also leads on review sentiment (100% vs 84%) and rating (5.0 vs 4.8). Intervals Pro's advantage is ratings volume (14K vs 9) and update cadence (every 8 days vs every 3 weeks). On price, ads, in-app purchases 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 and Python PTS sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Python PTS 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 9, 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 Python PTS's.

Intervals Pro ships an update every 8 days, Python PTS every 3 weeks. The most recent releases landed on October 3, 2026 and September 23, 2026 respectively.
