Verdict
The clearest difference is in-app purchases: On This Date at none against Interactive Quantum Mechanics's 1. On This Date also leads on iOS requirement (16.2 vs 26.2). Interactive Quantum Mechanics's advantage is ads (none vs shown) and update cadence (fortnightly vs every 2 months). On price and device support there is nothing between them.
