Verdict
The clearest difference is update cadence: Evidation at every 3 days against Apple Research's every 2 months. Evidation also leads on rating (4.6 vs 4.2) and ratings volume (29K vs 1.5K). On price, ads, in-app purchases and monetization model there is nothing between them.

Evidation holds the better App Store score, 4.6 against 4.2.

Evidation ships an update every 3 days, Apple Research every 2 months. Both last shipped on September 30, 2026.
