Verdict
The clearest difference is in-app purchases: Endura Virtual Challenges at none against Interval Timer's 1. Endura Virtual Challenges also leads on ads (none vs shown) and update cadence (every 4 days vs every 2 months). Interval Timer's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 15.1). On price there is nothing between them.
