# SUNI vs Red Light Therapy

The clearest difference is ads: SUNI at none against Red Light Therapy's shown. SUNI also leads on ratings volume (20 vs 3). Red Light Therapy's advantage is rating (4.7 vs 4.4) and iOS requirement (15.0 vs 18.0). On price, update cadence, in-app purchases and monetization model 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 Therapy sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Red Light Therapy holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: SUNI has 20 ratings behind it against 3, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on November 5, 2026.
