# ОНЛАЙН vs Space Explorer

The clearest difference is ads: ОНЛАЙН at none against Space Explorer's shown. ОНЛАЙН also leads on monetization model (free vs ad-supported) and iOS requirement (11.0 vs 16.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
