# Frame Rate vs Retinal

The clearest difference is in-app purchases: Retinal at none against Frame Rate's 1. Retinal also leads on ads (none vs shown) and update cadence (fortnightly vs every 10 months). Frame Rate's advantage is iOS requirement (14.0 vs 17.0). On price and device support there is nothing between them.
