# Observation vs YHUB

The clearest difference is ads: Observation at none against YHUB's shown. YHUB's advantage is iOS requirement (12.0 vs 15.1). 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.
