The short answer
SkinSort has ten different prices, a free trial that quietly turns into a charge, and reviewers say even basic search filters are now paywalled. Worse, it checks products one at a time, so it can miss the clash that actually hurts: two strong products on your face on the same night.
What that means: you can pay up to $59.99 a year and still wake up with a stinging face. ComfiSkin checks your whole week, for free, with nothing to renew.

Ten price tags and a trial that renews
SkinSort’s App Store listing shows ten in-app purchases at six different prices: monthly plans at $7.99 and $12.99, yearly plans from $19.99 to $59.99, and Premium at $35.99 and $39.99. Subscriptions renew automatically.1 When an app needs that many price tags, it’s been designed around billing, and you’ll spend more time working out which plan you’re on than checking your skincare.
Trials that quietly turn into charges are where the anger starts. When we checked, 12 of the 50 most recent App Store reviews gave one or two stars, several about trials and filters.2
“This app makes it nearly impossible to cancel your free trial.”
“…impossible to search with basic filters like region without upgrading.”
ComfiSkin has no trial and no plans. Search, filters and routines are all free, and nothing is held back to push you towards an upgrade.
What that means for you: forget a trial and you’re paying, and reviewers say getting out isn’t easy. With ComfiSkin, there’s nothing to forget.
It checks products, but your skin meets your routine
Knowing that two ingredients can irritate together is useful. Knowing that they both land on your face on Tuesday night is what actually saves your skin. Your face doesn’t meet products one at a time. It meets whatever you put on it that evening. One SkinSort user wrote that the app “does not show conflicts between products in your routine” as they plan each day, and asked for an active warning.2
That’s the gap that hurts. A strong acid toner and a retinol serum can each be “a match” on their own, and still leave you red and stinging when they meet. So you can pay for matching and still get the thing matching was supposed to prevent.
ComfiSkin is built around the routine. It knows which products you use on which nights, flags any evening where two strong products land together, and offers to move one to a clear night with a single tap.
What that means for you: two products that are each fine on their own can still irritate your skin together. ComfiSkin warns you before it happens. SkinSort, as you plan your week, won’t.
Ads on the website, tracking in the app
SkinSort’s privacy policy says its website works with Mediavine to show interest-based ads from third parties.3 On the App Store, the app lists identifiers as data used to track you.1 So you can be charged, shown ads and tracked by the same product. ComfiSkin shows no ads anywhere and keeps your skin notes on your phone.
What that means for you: paying doesn’t buy you out of being advertised to. With ComfiSkin, there’s no advertising to buy out of.
What to do if you use SkinSort
- If you’re in a free trial, decide now. Cancel it or set a reminder for the day before it renews. On an iPhone it’s under Settings, your name, then Subscriptions.
- Plan your nights, not just your products. Keep strong exfoliants and retinoids on different evenings unless you know your skin can take both.
- Let ComfiSkin do the checking. Add your products once and it watches your whole week for clashes, for free.
