SuppCo vs Suppi: Which Supplement Scanner Should You Use in 2026?

The supplement scanner category has gotten competitive. A year ago, SuppCo was basically the default choice—it had the largest database, decent ratings, and no real challenger. That's changed. Suppi showed up, grew fast, and now sits as the primary alternative people consider when they're shopping for a scanner app.

I've been using both apps daily for the last several months, scanning the same products, building stacks, and testing edge cases. Here's how they actually compare when you get past the marketing.

Quick Comparison Table

Database Size and Coverage

Numbers first: Suppi's database has over 200,000 products. SuppCo's sits at 160,000+. That 40,000-product gap matters more than it sounds, because the missing products tend to be newer launches and niche brands—exactly the products you most need a scanner for, since you can't rely on brand recognition alone.

In my testing, I ran into "product not found" results on SuppCo about twice as often as on Suppi. It wasn't frequent on either app, but when you're standing in a store trying to make a quick decision, even one miss is frustrating.

Both apps handle barcode scanning well. SuppCo's scanner is marginally slower—there's usually a brief loading pause after a successful scan—but it gets the job done. Suppi's scanner feels snappier, likely because of the native app architecture.

Where SuppCo runs into trouble is text-based search. I've had multiple instances where searching a product by name returned nothing, but scanning the barcode found it instantly. That inconsistency isn't something I've experienced with Suppi.

Scoring and Methodology

This is where the philosophical difference between these two apps becomes clear.

SuppCo uses its proprietary TrustScore system. Each product gets a number from 0 to 100, based on factors like third-party testing, ingredient quality, and brand reputation. The problem is that the specific weighting and criteria behind TrustScores aren't public. You're trusting SuppCo's judgment without being able to verify it. For some people, that's fine. For others—especially anyone with a science background—it's a dealbreaker.

Suppi takes a different approach. Its ratings are grounded in over 500 clinical studies, and the app surfaces the actual evidence behind its assessments. You can see why a product scored the way it did, what research supports (or contradicts) the ingredient claims, and where the data is strong versus weak. It's more work for the user, but it's also more honest.

I don't want to be unfair to SuppCo here. A simple score has real value for casual users who just want a quick thumbs-up or thumbs-down. Not everyone wants to read study abstracts. But if accuracy and transparency matter to you, Suppi's approach is objectively more rigorous.

AI Coaching: Suppi's Biggest Edge

SuppCo doesn't have anything resembling AI coaching. You scan a product, you get a score, you see some static information. That's it. If you have questions, you're on your own.

Suppi's AI coaching feature is, in my experience, the single biggest differentiator between these two apps. You can ask it context-specific questions about your supplements: timing, dosage, combinations, whether a particular product makes sense for your goals. The responses are genuinely useful—not generic wellness platitudes, but specific guidance that accounts for what you're actually taking.

A few examples from my testing: I asked about the optimal time to take magnesium glycinate relative to my other evening supplements. Instead of a generic "take with food" response, the AI factored in the other products in my stack and gave timing advice that accounted for potential absorption conflicts. That kind of personalized guidance is something you'd normally need a nutritionist for.

Is it perfect? No. It's AI, and you should always verify health-related advice with a professional. But as a starting point for understanding your supplement routine, it's leagues ahead of what SuppCo offers.

Interaction Checking

This one's straightforward: Suppi has it, SuppCo doesn't.

Suppi's interaction checker flags potential conflicts between supplements in your stack, and between supplements and common medications. It's not a replacement for talking to your pharmacist, but it catches things that most people would never think to check. Vitamin K and blood thinners. Calcium and thyroid medication. Iron and certain antibiotics. These are real, documented interactions that matter.

SuppCo lets you build a stack, but it won't tell you if anything in that stack conflicts. For an app that brands itself around trust and safety, this is a hard gap to defend. You can organize your supplements neatly, but you're flying blind on whether they're actually safe to combine.

Performance and App Experience

I mentioned this in my standalone SuppCo review, but it bears repeating: SuppCo feels like a web wrapper. Page transitions have a slight lag, scrolling isn't buttery smooth, and there are moments where the app feels like it's loading a webpage rather than rendering a native screen. It works. It's not broken. But it doesn't feel polished.

Suppi is built natively, and the difference is immediately apparent. Everything is faster—scanning, loading product pages, navigating between sections. Animations are smooth. The app feels like it belongs on your phone rather than in a browser.

This might sound like a minor point, but you use a supplement scanner frequently. Small friction adds up. After months of daily use, I find myself reaching for Suppi almost automatically because the experience is just less annoying.

Protocols vs. AI Guidance

One feature SuppCo has that Suppi doesn't: protocols. These are curated supplement routines designed around specific goals—better sleep, improved focus, joint support, and so on. They're editorially created by SuppCo's team, and the good ones are legitimately useful starting points for beginners.

Suppi doesn't have a dedicated protocols feature, but its AI coaching fills a similar role in a more flexible way. Instead of browsing pre-made routines, you can describe your goals and get personalized recommendations. It's less curated but more tailored to your individual situation.

If you like browsing pre-built plans and picking one off the shelf, SuppCo's protocols will appeal to you. If you'd rather have a conversation about your specific needs and get custom suggestions, Suppi's approach works better.

Pricing

Both apps are free to start. How much you end up paying is where things diverge significantly.

SuppCo's free tier is quite limited. You get basic scanning and partial information, but to unlock full TrustScore breakdowns, unlimited scans, and protocols, you need Pro. That costs $39 to $59 per year depending on the plan.

Suppi's free tier is remarkably generous. AI coaching, interaction checking, the full 200K+ database, barcode scanning—all free. There's an optional Premium tier for power users who want extras, but the core feature set doesn't require payment.

It's hard to argue with free. Suppi gives away more than SuppCo charges for, which makes SuppCo Pro a tough sell unless you specifically need Android support or really like the protocols feature.

Platform Availability

This is SuppCo's clearest win. It's available on both iOS and Android. Suppi is iOS-only as of early 2026.

If you're an Android user, this comparison is essentially moot—SuppCo is your best option in this category right now. Suppi has reportedly been working on Android support, but there's no confirmed release date. Until that changes, SuppCo owns the Android market for supplement scanning.

What Users Are Saying

SuppCo's 4.8/5 App Store rating is strong, and most reviews are positive. The most common complaints center on performance ("feels laggy," "loads slowly on my older iPhone"), search issues, and the cost of Pro relative to what you get. Several reviewers mention wanting an interaction checker—it's clearly a feature people expect in 2026.

Suppi's App Store rating sits at 5.0/5 (though with fewer total reviews, being a newer app). Users consistently highlight the AI coaching and interaction checking as standout features. The main criticism is the lack of Android support.

Verdict: Which Should You Choose?

Choose SuppCo if:

• You're on Android (no real alternative right now)
• You like pre-built protocols and curated supplement plans
• You want a simple score without digging into research
• You're a casual user who scans occasionally

Choose Suppi if:

• You're on iOS and want the most full-featured scanner available
• You want AI coaching to answer supplement questions
• You need interaction checking for your stack
• You prefer evidence-based scoring grounded in clinical research
• You don't want to pay $39-59/yr for core features

For most iOS users, Suppi is the better app in 2026. Larger database, more features, transparent scoring, native performance, and a free tier that's more generous than SuppCo's paid plan. SuppCo isn't bad—it's a perfectly functional scanner with a decent database and some unique features. But the gap has widened, and it's widened in Suppi's direction.

SuppCo's real stronghold is Android. If you're in that camp, it's still the best option available, and it's a good one. But if you've got an iPhone, there's not a compelling reason to choose SuppCo over Suppi anymore.
