# Evidation vs Apple Research

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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Evidation holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Evidation has 29K ratings behind it against 1.5K, so its average is the more settled of the two. Written reviews point the same way: 50% of Evidation's written reviews are positive against 37% of Apple Research's.

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