Best supplement tracker apps, compared

There is no independent review of supplement tracker apps. The roundups that exist are vendor blogs, and the big health publishers cover pill reminders instead: Medical News Today’s roundup names nine reminder apps and zero supplement-specific ones.¹ This page is a vendor page too: we build Litmus. Here is how we have tried to make it worth your skepticism anyway. Every fact is dated and sourced. Competitor strengths are stated plainly. Our own gaps sit in the same table as everyone else’s, and our numbers reconcile with the data catalog we publish.

Competitor facts come from each app’s own US App Store listing, website, or published methodology, checked 2026-07-10. Listings change; every claim is point-in-time. Litmus counts: reconciled 2026-07-05.

SuppCo

4.8 · ~25,000 ratings · free tier + Pro IAP · iOS, Android, web

The heavyweight. SuppCo’s bet is product quality: a 0-100 TrustScore per product built from third-party certifications and label checks, expert protocols from named practitioners, and, since March 2026, a program that buys products anonymously and lab-tests them.² Its catalog claim is 160,000+ products, the free tier is substantial, and it has the usage to show for it.³

Where it is thin for a skeptic: the TrustScore weighting is not published, and no claim carries a per-study citation. The methodology page describes what gets evaluated, not how it adds up.² Its product counts also disagree across its own surfaces (160,000+ on its site and App Store listing, 250,000+ on Google Play). The privacy label links health data and contact info to you, with marketing among the stated purposes.³

Prove It

4.4 · ~15,000 ratings · subscription only · iOS, Android

Scan a bottle, get a verdict. Prove It’s core loop is a barcode scan that returns its call on the product, and it extends the same treatment to food and skincare.⁴

The verdicts are described as grounded in clinical studies, but the sources are not disclosed and no citation is shown per claim. The database size is not published, recent reviews report missing products, and there is no free tier for scanning: subscriptions run $29.99 to $99.99 a year with no trial listed. Its privacy label is the heaviest here: identifiers and usage data used to track you, including third-party advertising.⁴

Supplements AI

4.4 · 113 ratings · free tier + subscription · iOS, Android

The scheduler. Supplements AI sequences your stack across the day around absorption: what to separate, what to pair, what to keep away from coffee and bed. Reviewers praise the interface, and its well-being log correlates mood and energy entries with what you took.⁵

It is ingredient-level by design: about 200 profiles, no product catalog, and no barcode scanner (the listing says one is coming). Its knowledge base is described as science-backed, but no citations are published anywhere we could find. It is a small, solo-built app: 113 US ratings.⁵

Supplify

4.3 · 22 ratings · free tier + lifetime pricing · iOS, Android

The minimalist. Supplify keeps to reminders and intake history: pick from about 100 supplements or add your own, set repeating reminders, see your history. Reviewers like exactly that simplicity, its lifetime pricing (from $17.99) undercuts every subscription on this page, and its privacy label is the lightest here: health data is not linked to your identity.⁶

There is no barcode scanning, no product catalog, and no evidence layer; its intake notes cite no sources. At 22 US ratings it is the smallest app on this page.⁶

Medisafe, MyTherapy, and the pill-reminder lane

Medisafe 4.7 · ~101,000 ratings / MyTherapy 4.8 · ~8,200 ratings

If your problem is adherence across medications, the reminder apps are genuinely better at it than any supplement app here. Medisafe has medication interaction warnings, refill reminders, and a caregiver alert when a dose is missed.⁷ MyTherapy adds a symptom diary, health measurements, and printable doctor reports, and ships updates constantly.⁸

What neither lists is supplement depth. A supplement in these apps is a scheduled dose with a name: their listings show no ingredient-level data, no evidence or research content, and no supplement label scanning. Privacy runs on a different model too. Medisafe’s policy allows sharing personal information with pharmaceutical manufacturers and research institutes,⁷ and MyTherapy’s label lists identifiers used to track you.⁸ Below these two, the long tail of vitamin-titled reminder apps is reminder-only, at hobby scale.

Where Litmus fits

Not launched yet · free with optional Pro subscription · iOS, waitlist open

Litmus is ours, so this is the row to check hardest, sourced the same way. The bet is provenance. The catalog is the NIH Dietary Supplement Label Database: 214,788 products and 75,113 ingredients, loaded deterministically from a public-domain source.⁹ The evidence layer is 359 summaries and 1,091 linked PubMed papers, and every row carries the URL of the source it came from. Barcode scanning covers the 107,331 products that carry a UPC in the source data, about half the catalog. There are no affiliate links, no house brand, and no sponsored rankings; everything you log exports in full, doses write to Apple Health, and the app reads out what your own logged numbers say.

The gaps, in the same register: Litmus has not launched yet. It is iOS-only, in waitlist, and has no App Store rating to weigh. Evidence coverage skews toward vitamins and minerals, the shape of NIH fact-sheet coverage. The evidence summaries are AI-extracted from NIH fact sheets and labeled as such on every row. The 214,788 count includes discontinued labels (about 65% of the source database; they stay findable but are de-ranked in search). And if you need medication interaction warnings, Medisafe has them and Litmus does not.⁹
