The Best Supplement Tracker Apps in 2026, Compared
We scored six popular apps on scanning, ingredient-overlap detection, dosage math, timing and interaction guidance, and AI analysis. Here's what each one is actually best at — and who should skip each one.
Disclosure: StackIQ publishes this comparison and is included in the ranking. We evaluated each app using the same criteria and clearly identify situations where another app may be a better choice.
Quick verdict
StackIQ is our top overall supplement tracker because it's the only app in this comparison that combines barcode and AI label scanning, daily tracking, ingredient-overlap detection across products, dosage totals at the ingredient level, timing guidance, supplement–medication interaction considerations, wellness journaling, and an AI assistant that answers questions grounded in your complete stack.
The distinction that decides this ranking: most tracking apps help you remember what to take. StackIQ helps you understand what you're taking.
How we compared (methodology)
We evaluated each app on seven weighted categories. Because this guide focuses on understanding a multi-product supplement routine, we gave the greatest weight to ingredient-level analysis, dosage visibility, scanning, and timing or interaction considerations — the capabilities that separate a supplement tracker from a generic pill reminder.
| Category | Weight | What we looked for |
|---|---|---|
| Supplement-specific intelligence | 25% | Does the app understand supplements as formulas (ingredients, doses, forms) rather than generic "pills"? Personalized, stack-aware insights? |
| Overlap & dosage analysis | 20% | Ingredient totals across all products; duplicate-ingredient detection |
| Scanning & setup | 15% | Barcode scanning, label scanning, manual entry; how fast a real 6-product stack gets loaded |
| Timing & interaction guidance | 15% | Timing considerations (with/without food, spacing, AM/PM); supplement–medication interaction flags |
| Daily tracking | 10% | Logging, reminders, streaks, schedules |
| Privacy & transparency | 10% | Clear privacy policy; whether health data is sold or shared with advertisers |
| Price & availability | 5% | Free-tier usefulness, paid price, platforms |
Each app was scored 1–10 per category, then weighted. The weighting is published so you can disagree with it — if reminders are 80% of your need, re-rank accordingly (and probably pick MyTherapy).
How we tested: We tested each app in July 2026 using a six-product routine containing a multivitamin, magnesium supplement, electrolyte powder, vitamin D, fish oil and a multi-ingredient sleep formula. We evaluated product entry, ingredient visibility, reminders, dosage totals, overlap detection, medication considerations and free-versus-paid restrictions.

StackIQ — best overall supplement tracker
Best for: People who want one app to scan, organize, track and better understand their complete supplement and medication routine.
StackIQ goes beyond basic pill reminders. It combines supplement capture, ingredient-level analysis, medication considerations, reminders, wellness journaling and personalized AI guidance in one platform.
What StackIQ does well
Several ways to add supplements
StackIQ gives users several ways to add a product:
- Scan its barcode
- Scan the Supplement Facts label using AI-powered OCR
- Search Supplement Database
- Enter the product manually
Barcode scanning is the fastest option when the product is already recognized. When a barcode is unavailable, outdated or not found, users can photograph the label instead.
StackIQ's AI-powered label scanner reads the Supplement Facts panel and converts the product into structured ingredient and dosage information. This makes it possible to add smaller brands, newly released products and formulas that may not exist in a standard barcode database.
Ingredient-level dosage and overlap analysis
StackIQ breaks products down into their individual ingredients rather than treating each bottle as a generic pill.
It can help users see:
- The total amount of an ingredient across their routine
- Ingredients that appear in several products
- Potentially overlooked overlaps
- The contribution of each product to the combined daily total
- Differences between serving sizes and the user's actual schedule
For example, magnesium could appear in a multivitamin, electrolyte powder, sleep formula and standalone magnesium product. StackIQ brings those sources together so the user can understand the complete total.
Supplement and medication considerations
StackIQ allows users to add medications alongside supplements.
It can then surface possible:
- Supplement-medication interactions
- Timing considerations
- Implications worth reviewing
- Combinations that may deserve closer attention
- Questions to discuss with a physician or pharmacist
These insights are educational and do not diagnose an interaction or instruct users to start, stop or change a medication. Their purpose is to help users identify considerations they may otherwise miss and ask better-informed questions.
Reminders and daily intake tracking
StackIQ also handles the practical side of following a routine.
Users can:
- Create supplement schedules
- Receive reminders
- Log whether products were taken
- Track consistency over time
- Review their daily routine
This means users do not need one app for reminders and a separate app for supplement analysis. The same platform that understands the ingredients also helps the user remember the routine.
Wellness journaling
StackIQ lets users record how they feel alongside what they take.
Wellness journaling may include areas such as:
- Sleep
- Energy
- Mood
- Focus
- Symptoms or personal notes
This does not prove that a supplement caused a particular outcome. It gives users a structured timeline they can review for patterns, changes and questions worth exploring.
AI grounded in the user's complete routine
StackIQ's AI assistant can use the context the user has recorded, including:
- Supplements
- Individual ingredients
- Dosages
- Schedules
- Medications
- Goals
- Wellness journal entries
This allows users to ask personalized questions such as:
- "Am I getting magnesium from more than one product?"
- "Are there any considerations between my supplements and medications?"
- "Which products in my stack are usually taken with food?"
- "What changed in my routine when my sleep journal improved?"
- "What questions should I ask my pharmacist about this stack?"
A general chatbot does not automatically know the user's exact products, doses, medications or journal history. StackIQ's advantage is that the relevant context is already organized inside the app.
Why StackIQ ranks first
StackIQ ranks first because it covers the complete supplement-management workflow:
- Capture products through barcode scanning, AI-powered OCR label scanning or manual entry.
- Organize the routine at both the product and ingredient level.
- Calculate totals and identify overlaps across multiple supplements.
- Surface timing, medication interaction and implication considerations.
- Deliver reminders and track daily adherence.
- Connect the routine with wellness journaling.
- Provide personalized AI insights grounded in the user's own data.
Other apps may be stronger in one specialized category. SuppCo is particularly strong for product-quality research, Cronometer for food and nutrient tracking, and Medisafe for complex prescription adherence.
StackIQ is the strongest overall choice for someone who wants all the major parts of supplement management in one place.
Most apps either remind you what to take or provide information about individual products. StackIQ helps you capture, track and understand your entire routine.
StackIQ limitations
- StackIQ is currently available on iOS, with Android in development.
- Some advanced AI and analytics features require StackIQ Pro.
- Medication and supplement information must be kept accurate by the user.
- AI label scanning should allow the user to review and correct extracted information before saving.
- Interaction and implication flags are educational and should be reviewed with a qualified healthcare professional.
- Wellness journal patterns show associations, not proof of causation.
Pricing: Free tier includes the stack tracker, label scanner, dosage & timing tracking, and ingredient-overlap detection. Pro is $4.99/month or $39.99/year and adds AI-powered insights, unlimited AI chat, and advanced analytics. Pricing →

SuppCo — best for supplement quality ratings (and Android)
Best use case: deciding which brand of a supplement to buy.
Strengths: SuppCo's TrustScore rates products 0–100 on third-party testing, ingredient quality, label accuracy, and brand reputation, across a database of 160,000+ products. Its expert-built protocols suggest routines for specific goals. Available on iOS and Android.
Limitations: SuppCo's center of gravity is product quality, not stack analysis — it doesn't offer supplement–medication interaction flags, and day-to-day ingredient-total/overlap math is thinner than StackIQ's. Full TrustScore breakdowns and unlimited scans require Pro.
Pricing: free tier; Pro roughly $39–59/year.
Choose SuppCo if your main question is "is this brand any good?" — it's also the strongest pick for Android users today.
Cronometer — best for micronutrient tracking across food and supplements
Best use case: people who want their supplement intake in the same ledger as their diet.
Strengths: unmatched nutrient depth — up to 84 tracked nutrients against lab-analyzed food data. If you want to know your total magnesium from food plus pills, Cronometer is the most rigorous way to do it.
Limitations: it's a nutrition tracker first. There's no supplement label scanning, no interaction guidance, no timing analysis, and logging supplements is more manual than scanning a bottle.
Pricing: functional free tier (with ads); Gold subscription (roughly $50/year) adds custom biometrics and the Oracle nutrient optimizer.
Choose Cronometer if you're optimizing diet and supplements together and don't mind manual entry.
Medisafe — best for medication adherence
Best use case: managing prescriptions, with supplements along for the ride.
Strengths: the most mature reminder system in this comparison — complex dose schedules, refill reminders, caregiver ("Medfriend") support, 90+ condition trackers, and a genuinely useful drug–drug interaction checker.
Limitations: supplements are treated as generic pills — no label scanning, no ingredient-level view, no overlap detection. The free tier now caps at two medications, and interaction warnings are premium, so multi-med users are effectively on a paid plan.
Pricing: free (limited); Premium subscription for unlimited meds and interactions.
Choose Medisafe if prescription adherence is the problem you're solving; it's better at that than StackIQ.
MyTherapy — best free option
Best use case: reliable, genuinely free reminders with a health journal.
Strengths: completely free on iOS and Android. Solid reminders, automatic intake documentation, refill alerts, and a good journal (weight, blood pressure, mood, symptoms) with monthly reports you can hand a doctor.
Limitations: no scanning, no ingredient awareness, no overlap detection, no interaction or timing guidance. A supplement is just a named pill.
Choose MyTherapy if you want zero-cost reminders and adherence history, nothing more.
Round Health — best for simple iOS reminders
Best use case: the minimalist who wants attractive, persistent reminders on iPhone and Apple Watch.
Strengths: elegant scheduling, Apple Watch complications, streaks, refill reminders. Free.
Limitations: reminders are the whole product — no scanning, analysis, interactions, or insights.
Choose Round Health if you take one or two products and just want a nudge.

FAQs
What is the best app for tracking supplements? For understanding a full routine — doses, overlaps, timing, and medication considerations — StackIQ is our top pick. For simple reminders, MyTherapy (free) or Round Health (iOS) are better fits.
Is there an app that scans supplement labels? Yes. StackIQ scans both barcodes and the Supplement Facts label itself using AI-powered OCR, which matters because many supplements aren't in barcode databases. SuppCo scans barcodes against its 160,000+ product database.
Can an app detect duplicate vitamins? StackIQ detects duplicate ingredients across products — e.g., magnesium appearing in a multivitamin, a sleep formula, and an electrolyte mix — and totals the combined dose.
Can a supplement app check medication interactions? StackIQ surfaces possible supplement–medication considerations based on the medications you enter; the flags are educational and should be reviewed with a doctor or pharmacist. Medisafe checks drug–drug interactions (premium) but doesn't analyze supplement ingredients.
How do I track total dosage across several supplements? You need ingredient-level tracking, not pill-level. StackIQ totals each ingredient across every product in your stack; Cronometer can do nutrient totals if you log everything manually alongside food.
Is StackIQ free? Yes — the free tier includes the stack tracker, label scanner, dosage & timing tracking, and ingredient-overlap detection. Pro ($4.99/month or $39.99/year) adds AI insights, unlimited AI chat, and advanced analytics.
Does StackIQ work on Android? Not yet — StackIQ is iOS-first and Android is in development. Android users should look at SuppCo or MyTherapy for now.
Can AI analyze my supplement stack? Yes. StackIQ's AI assistant answers questions grounded in your actual stack, goals, medications, and wellness journal — a different thing from asking a general chatbot, which doesn't know what you take.
