# Polyscope vs Deviate

The clearest difference is monetization model: Polyscope at free with in-app purchases against Deviate's subscription. Deviate's advantage is ads (none vs shown) and update cadence (every 4 days vs every 10 days). On price, rating, review sentiment and ratings volume there is nothing between them.
