# Othership vs ISRU

The clearest difference is ads: Othership at none against ISRU's shown. Othership also leads on review sentiment (100% vs 65%) and rating (5.0 vs 4.7). ISRU's advantage is update cadence (every 6 days vs monthly) and device support (3 vs 1). On price and in-app purchases there is nothing between them.

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