Verdict

The call

The clearest difference is in-app purchases: DynoForce at none against Interval Timer's 1. DynoForce also leads on ads (none vs shown) and update cadence (every 6 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.
