# Hotmoon vs Light Sleep

The clearest difference is review sentiment: Light Sleep at 83% against Hotmoon's 23%. Light Sleep also leads on rating (4.7 vs 3.2) and update cadence (every 3 days vs fortnightly). Hotmoon's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Hotmoon sells 2 in-app purchases, starting at $4.99 per month and Light Sleep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Light Sleep holds the better App Store score, 4.7 against 3.2. Both are backed by a comparable volume of ratings — 42 and 46 respectively. Written reviews point the same way: 23% of Hotmoon's written reviews are positive against 83% of Light Sleep's.
