# SkinIO vs 30% Formula

The clearest difference is ads: SkinIO at none against 30% Formula's shown. SkinIO also leads on ratings volume (64 vs 3) and monetization model (free vs ad-supported). 30% Formula's advantage is rating (5.0 vs 4.6). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

30% Formula holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: SkinIO has 64 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 96% of SkinIO's written reviews are positive against 100% of 30% Formula's.

SkinIO ships an update monthly, 30% Formula every 3 weeks. The most recent releases landed on November 2, 2026 and November 5, 2026 respectively.
