# Exoplanet vs TrueSize

The clearest difference is ads: Exoplanet at none against TrueSize's shown. Exoplanet also leads on review sentiment (91% vs 72%) and ratings volume (975 vs 306). TrueSize's advantage is monetization model (free vs free with in-app purchases). On price, rating, update cadence and in-app purchases there is nothing between them.
