# Flow Free vs DOP 2

The clearest difference is review sentiment: Flow Free at 82% against DOP 2's 49%. Flow Free also leads on rating (4.8 vs 4.6) and chart position (#41 vs unranked). DOP 2's advantage is update cadence (every 3 weeks vs every 5 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Flow Free sells 10 one-off in-app purchases and DOP 2 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Flow Free holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 401K and 289K respectively. Written reviews point the same way: 82% of Flow Free's written reviews are positive against 49% of DOP 2's.
