ToxFree vs Think Dirty: which non-toxic scanner fits you?
Think Dirty and ToxFree both scan beauty and personal care products and rate their ingredients. They're built for slightly different people, so here's a straight comparison using each app's own App Store listing (checked October 6, 2026).

Where Think Dirty is stronger
Think Dirty has been around for years, has a much bigger database and audience, and suggests cleaner alternatives and curated product lists. If you mainly want help finding replacement products to buy, that's a real advantage. ToxFree doesn't suggest swaps.
Where ToxFree is different
ToxFree opens every scan with the hormone question: which ingredients have been linked to hormone disruption, and why. Each flag names the regulator or study behind it, so a confirmed hormone disruptor never scores like a well-studied preservative. ToxFree also adds up everything you use in a day, so you can see your hormone flags across your whole routine, not one product at a time.
Which should you choose?
Choose Think Dirty if you want the largest database and product recommendations. Choose ToxFree if your main question is hormones, for example if you're trying to conceive, pregnant, or managing PCOS or a thyroid condition, and you want to see the evidence behind each flag.
FAQ
Is ToxFree free like Think Dirty?
Both are free to download. ToxFree's scanning is part of Pro, with a 7-day free trial on the monthly plan. Think Dirty's real-time scanning and personal preferences are part of its Premium plans.
Does ToxFree suggest cleaner products?
No. ToxFree tells you what's in a product and why each flagged ingredient matters. It doesn't recommend products to buy.
Can a brand pay ToxFree for a better score?
No. ToxFree takes no money from the brands it scores, and the score comes from a formula, so the same ingredients always get the same result.
Try ToxFree on your own products. Scan a barcode or ingredient label to get a 0–10 score and every hormone flag, with the reason for each.
