Verdict
The clearest difference is in-app purchases: Python PTS at none against Interval Timer's 1. Python PTS also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). Interval Timer's advantage is ratings volume (250 vs 9) and iOS requirement (13.0 vs 15.0). On price, rating and device support there is nothing between them.
