# Python PTS vs Interval Timer

The clearest difference is monetization model: Python PTS at free against Interval Timer's subscription. Python PTS also leads on review sentiment (100% vs 67%) and rating (5.0 vs 4.7). Interval Timer's advantage is ratings volume (3.5K vs 9). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Python PTS sells 1 one-off in-app purchase and Interval Timer sells 12 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Python PTS holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Interval Timer has 3.5K ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 100% of Python PTS's written reviews are positive against 67% of Interval Timer's.

Python PTS ships an update every 3 weeks, Interval Timer every 4 weeks. The most recent releases landed on September 23, 2026 and October 9, 2026 respectively.
