# Python PTS vs Interval Timer

The clearest difference is ads: Python PTS at none against Interval Timer's shown. Python PTS also leads on monetization model (free vs free with in-app purchases) and update cadence (every 3 weeks vs every 2 months). Interval Timer's advantage is ratings volume (246 vs 9) and iOS requirement (13.0 vs 15.0). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Python PTS sells 1 one-off in-app purchase and Interval Timer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Python PTS against 4.9 for Interval Timer. That said, the two scores are not equally well evidenced: Interval Timer has 246 ratings behind it against 9, so its average is the more settled of the two. Written reviews are what separate them: 100% of Python PTS's written reviews are positive against 84% of Interval Timer's.

Python PTS ships an update every 3 weeks, Interval Timer every 2 months. The most recent releases landed on June 6, 2026 and September 23, 2026 respectively.
