Verdict
The clearest difference is update cadence: Epi Tools at every 2 months against PAHO Virtual Campus's every 8 months. Epi Tools also leads on iOS requirement (13.4 vs 15.0). PAHO Virtual Campus's advantage is ratings volume (12 vs 1). On price, rating, review sentiment and ads there is nothing between them.
