# 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). Interval Timer's advantage is ratings volume (379 vs 9). On price, rating, review sentiment and update cadence 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 $2.09 per month. 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 379 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 97% of Interval Timer's.

Python PTS ships an update every 3 weeks, Interval Timer monthly. The most recent releases landed on June 6, 2026 and September 25, 2026 respectively.
