# SUNI vs Red Light for Sleeping

The clearest difference is rating: Red Light for Sleeping at 5.0 against SUNI's 4.4. Red Light for Sleeping also leads on update cadence (every 9 days vs every 3 weeks). SUNI's advantage is ratings volume (20 vs 4). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. SUNI sells 6 in-app purchases, starting at $9.99 per 7 days and Red Light for Sleeping sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Red Light for Sleeping holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: SUNI has 20 ratings behind it against 4, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

SUNI ships an update every 3 weeks, Red Light for Sleeping every 9 days. The most recent releases landed on November 5, 2026 and November 1, 2026 respectively.
