# DoubleFeel vs Luuupa

The clearest difference is rating: DoubleFeel at 4.8 against Luuupa's 4.1. Luuupa's advantage is review sentiment (50% vs 41%) and iOS requirement (15 vs 17). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. DoubleFeel sells 10 in-app purchases, starting at $2.99 per month and Luuupa sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

DoubleFeel holds the better App Store score, 4.8 against 4.1. Both are backed by a comparable volume of ratings — 14 and 10 respectively. Written reviews complicate that: 41% of DoubleFeel's written reviews are positive against 50% of Luuupa's, so the app with the better star average is not the one people write more warmly about.

DoubleFeel ships an update every 9 days, Luuupa weekly. Both last shipped on November 5, 2026.
