Scan with OsanaQuick answer: what is the best Oasis Health app alternative?
It depends on which part of Oasis you actually use. For packaged food and grocery ingredients — the category Oasis has only just started to cover — Osana is our recommended pick. It gives you a 0–100 score built from nutrition, additives, and ultra-processing (NOVA), plus a photo-scan fallback when a barcode has no match.
If what you value about Oasis is the independent, lab-funded testing model, Clean Label Project is the closest match: it's a free, nonprofit app that pays accredited labs to test food and supplements for heavy metals, pesticides, and plasticizers. If you want the largest free database plus a tap water lookup by ZIP code, EWG Healthy Living is the strongest option. And if your main concern is cosmetics and personal care, a category Oasis barely touches, Think Dirty is built specifically for that.
No single app on this list fully replaces Oasis's specific niche of independently lab-tested water, filter, and air purifier rankings — that combination is still fairly unique. This guide is about the closest and most useful alternatives for each piece of what Oasis does.
What Oasis Health actually does
Oasis (also listed as "Oasis – What's Healthy" or "Oasis – Water Rankings") positions itself as an independent, lab-funded ratings platform. Instead of relying only on ingredient databases, Oasis says it purchases products at retail and pays for accredited lab testing, then publishes purity and safety ratings. It started with bottled water, water filters, and air purifiers, and has been expanding into supplements and food.
Pricing is a free tier plus Oasis Pro at $47/year for top rankings and advanced features. App Store copy describes the free tier as including access to all lab results and reports, though it's worth noting that a number of user reviews on both app stores describe most rankings and personalized recommendations sitting behind the Pro paywall in practice — so what's actually free can vary by what you're trying to look up.
Oasis is a genuinely useful idea: most shoppers have no way to know whether a product's purity claims hold up, and funding lab tests instead of running on ads is a reasonable trust model. But it's not the only way to solve that problem, and it isn't the best fit for every category or every budget.
Why shoppers look for apps like Oasis
- They want a free option instead of a $47/year subscription.
- Their main day-to-day question is about packaged food and additives, not water or filters.
- They want a tap water report for their specific ZIP code, not just bottled water rankings.
- They care about cosmetics, skincare, or personal care, categories Oasis doesn't meaningfully cover yet.
- They've hit the paywall or inconsistent ratings some reviewers report (duplicate listings, differing scores for the same product) and want a second opinion.
- They want an Android-first or barcode-first scanning flow rather than manual entry.
Oasis Health alternatives compared
| App | Availability | Price | How it evaluates products | Best for |
|---|---|---|---|---|
 Osana |   iOS & Android | Free, Premium ~$49.99/yr | 0–100 score from nutrition, additives, NOVA processing, and preferences | Packaged food and grocery ingredients |
 Clean Label Project | iOS & Android | Free (nonprofit) | Independent ISO-accredited lab testing for heavy metals, pesticides, plasticizers | Free lab-tested food & supplement certification |
 EWG Healthy Living | iOS & Android | Free, always unlimited | Science-backed hazard ratings across 200,000+ food, cosmetic, and cleaning products | Largest free database + tap water lookup |
 Think Dirty | iOS & Android | Free, Premium ~$2–5/mo | 0–10 "Dirty Meter" based on ingredient chemistry | Cosmetics and personal care |

1. Osana: the best Oasis alternative for food and grocery ingredients
Osana for iPhone and Osana for Android are built around a question Oasis is only starting to answer: what's actually in this packaged food, and what should I buy instead?
A barcode scan returns a score from 0 to 100 based on nutritional quality, additives, NOVA ultra-processing level, and your own preferences (seed oils, added sugar, high sodium, gluten). If a barcode doesn't return a result, Osana can analyze a photo of the ingredient label instead — useful for store brands and smaller labels that a database-only tool might miss.
Osana includes:
- barcode scanning and ingredient-label photo analysis;
- plain-English ingredient and additive explanations;
- ultra-processed food identification using NOVA;
- preference-aware scoring;
- scan history and healthier alternatives;
- a free tier, with premium around $49.99/year.
Where Osana is honest about its limits: it doesn't run its own accredited lab tests, and it doesn't cover water, filters, air purifiers, or cosmetics — Oasis's original categories. If your priority is exactly what Oasis started with, look at Clean Label Project or EWG below instead. But for the everyday task of scanning what's in your cart at the grocery store, Osana is the more focused, food-first tool.
2. Clean Label Project: best free, lab-tested alternative
Clean Label Project is the alternative closest to Oasis's actual methodology. It's a national nonprofit that buys products at retail and sends them to ISO-accredited labs for testing — heavy metals, pesticide residues, glyphosate, and plasticizers like BPA and phthalates — then certifies the products that meet its standards.
Its free app lets you browse thousands of certified products, build a grocery list from them, and read category-level testing reports. Coverage leans toward baby food and infant formula, protein powder, supplements, snack bars, coffee, and pet food rather than water or air purifiers specifically.
Choose Clean Label Project if what you liked about Oasis was the "someone actually paid to test this in a lab" model, and you want that for food and supplements at no cost.
3. EWG Healthy Living: best free, comprehensive database
EWG Healthy Living comes from the Environmental Working Group, a nonprofit that has published consumer safety research since the 1990s. The app combines three of EWG's databases — Skin Deep for cosmetics, Food Scores, and the Guide to Healthy Cleaning — covering more than 200,000 rated products, and it's explicitly always free and unlimited.
Its standout feature for anyone coming from Oasis is the EWG Tap Water Database: search by ZIP code to see contaminants detected by your local utility, compared against EWG's health guidelines, along with which filter types actually address them. It's not a substitute for testing your own tap, but it's the most useful free starting point for the water question Oasis addresses through bottled water and filter rankings.
Choose EWG if you want the broadest free database and a genuinely useful tap water report, even though EWG doesn't independently lab-test individual air purifiers the way Oasis does.
4. Think Dirty: best for cosmetics and personal care
Think Dirty is the pick if your real concern is skincare, makeup, or personal care — a category Oasis has only touched on (some reviewers have flagged toothpaste and personal care items) and doesn't cover systematically.
Scan a barcode and Think Dirty returns a "Dirty Meter" score from 0 (cleanest) to 10, based purely on the chemistry of the ingredients rather than brand reputation. The database covers more than 2.6 million products across skincare, hair care, cosmetics, household, baby, and pet items. The core scan-and-score experience is free; a Premium/All Access subscription (roughly $2–$5/month depending on the plan) adds personalized allergen alerts and deeper ingredient breakdowns.
Choose Think Dirty if cosmetics and personal care are what you actually want rated, not water or supplements.

How to compare these apps in your own kitchen
Pick three items you buy regularly: a bottled water or filter, a packaged food with a long ingredient list, and one personal care product. Test each one across two or three of the apps above and check whether each app:
- recognizes the product, or offers a useful fallback when it doesn't;
- explains why something is flagged, not just a color or number;
- matches the specific thing you personally care about (a heavy metal, an additive, a fragrance ingredient);
- suggests a realistic swap you'd actually buy;
- is worth what it costs you, free or not.
No app, including Oasis, replaces reading the actual label — especially for allergies or a real medical concern. The value of any of these tools is making that label faster to understand.
Which alternative should you download?
Choose Osana if your main goal is scanning packaged food for additives, ultra-processing, and personal preferences without a subscription commitment.
Choose Clean Label Project if you want the free version of Oasis's own lab-testing model, applied to food and supplements.
Choose EWG Healthy Living if you want the single largest free database plus a real tap water report for your address.
Choose Think Dirty if cosmetics and personal care are your actual concern.
Stay with Oasis if bottled water, filter, and air purifier rankings backed by independent lab testing are specifically what you need, and the $47/year Pro plan fits your budget.
Frequently asked questions
Is there a free alternative to Oasis Health?
Yes. EWG Healthy Living and Clean Label Project are both free, nonprofit apps with no paid tier. Osana and Think Dirty are free to download and scan, with optional premium subscriptions for deeper personalization.
Which Oasis alternative actually lab-tests products like Oasis does?
Clean Label Project is the closest match. Like Oasis, it purchases products at retail and pays accredited labs to test them, rather than relying only on ingredient databases.
Which app checks tap water contamination, not just bottled water?
The EWG Tap Water Database lets you search by ZIP code to see what's been detected in your local water supply and which filters address it. It's the closest free alternative to Oasis's water-focused rankings.
Which alternative is best for everyday grocery shopping?
Osana, for scanning packaged food and understanding additives, ultra-processing, and ingredients at the shelf.
Do any of these apps fully replace Oasis's air purifier rankings?
Not directly. None of the four alternatives above independently lab-test air purifiers the way Oasis does; this remains one of the more specific things Oasis offers.
Is Osana better than Oasis?
They cover different ground. Oasis is built around independently lab-testing water, filters, and air purifiers. Osana is built around scanning packaged food for additives and processing. If your daily use case is grocery shopping, Osana is the more focused tool; if it's water, filters, or air purifiers, Oasis is more specialized.
