# Space Defence vs RETRO

The clearest difference is in-app purchases: Space Defence at none against RETRO's 1. Space Defence also leads on ads (none vs shown) and iOS requirement (6.0 vs 15.0). On price and device support there is nothing between them.

Both are free to download. RETRO sells 1 one-off in-app purchase. Space Defence asks for nothing beyond the download.
