# SkinLens vs Trigger

The clearest difference is ads: Trigger at none against SkinLens's shown. Trigger also leads on iOS requirement (15.1 vs 18.6). SkinLens's advantage is update cadence (every 3 days vs weekly). On price, in-app purchases and device support there is nothing between them.

Both are free to download. SkinLens sells 4 in-app purchases, starting at $5.99 per 7 days and Trigger sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

SkinLens ships an update every 3 days, Trigger weekly. Both last shipped on October 31, 2026.
