# Engross vs Smart Sloth

The clearest difference is rating: Engross at 4.6 against Smart Sloth's 4.1. Smart Sloth's advantage is review sentiment (79% vs 49%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Engross sells 1 one-off in-app purchase and Smart Sloth sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Engross holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 46 and 33 respectively. Written reviews complicate that: 49% of Engross's written reviews are positive against 79% of Smart Sloth's, so the app with the better star average is not the one people write more warmly about.

Engross ships an update every 4 weeks, Smart Sloth every 2 months. The most recent releases landed on October 20, 2026 and October 25, 2026 respectively.
