# Retro Flash vs CompSesh

The clearest difference is update cadence: CompSesh at every 6 days against Retro Flash's every 3 weeks. CompSesh also leads on review sentiment (100% vs 83%) and rating (4.9 vs 4.7). Retro Flash's advantage is ratings volume (226 vs 7) and iOS requirement (15.6 vs 18). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Retro Flash sells 8 one-off in-app purchases and CompSesh sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
