Taking multiple supplements every day? The hard part is not remembering them — it is knowing what goes together, what needs spacing, and when each one works best. StackFlow turns supplement chaos into a clear, executable daily system. BUILT ON 200K+ REAL SUPPLEMENT PRODUCTS Search or scan real products with real ingredients, real serving sizes, and real label facts — not a generic vitamin list. INGREDIENT-LEVEL INTELLIGENCE StackFlow maps each product to its actual ingredients, so you understand what you are really taking — not just the brand name on the bottle. SCAN A LABEL, ADD IN SECONDS Point your camera at any supplement label. StackFlow reads the product, maps the ingredients, and places it into your routine. AI TIMING PLANS THAT EXPLAIN WHY Get timing suggestions based on ingredient interactions, absorption rules, and your current stack. Every recommendation shows the reasoning behind it. SYNERGY AND SPACING, MADE VISIBLE See which supplements work better together, which ones need to be spaced apart, and why your routine is organized the way it is. YOUR DAILY COMMAND CENTER Open StackFlow each morning. See exactly what to take now, check off each time slot, and keep your routine moving without guesswork. TRACK HOW YOUR BODY RESPONDS Log energy, sleep, digestion, and other signals. Over time, connect your routine to what you actually notice. DAILY INSIGHTS FEED (PRO) Receive a curated daily digest based on your stack, check-ins, and patterns — not a generic health tip, but intelligence about your specific routine. StackFlow is built for people who take supplement routines seriously. It is not medical advice, diagnosis, or treatment.

Here's the full description: Partiqule scores any product from 1 to 10 on ingredient safety and health impact. Food, personal care, baby products, home goods, clothing — if it has ingredients, Partiqule scores it. Every score runs two independent research passes grounded in peer-reviewed science from NEJM, Nature Medicine, and The Lancet. No brand can pay to change a score. No advertising. No sponsored results. WHAT YOU CAN SCAN Type any product name and get an instant health score with a full breakdown of what's flagged and why. Or use the camera to photograph a product label, tag, or packaging and let Partiqule identify and score it automatically. KIDS MODE Toggle Kids Mode to see how any product scores specifically for children. Children's developing organ systems are more sensitive to synthetic dyes, hormone disruptors, and ultra-processed ingredients. M&Ms score 7 out of 10 for adults — they score 9 out of 10 for kids, because four FDA-flagged petroleum dyes have confirmed links to hyperactivity and neurodevelopment disruption in children. Kids Mode adjusts daily value thresholds for sugar, sodium, and saturated fat to reflect children's recommended limits. NUTRITION BADGES For food and beverage products, Partiqule shows sugar, sodium, and saturated fat as a percentage of daily recommended values — and automatically switches to children's daily values when Kids Mode is active. See at a glance whether a product blows through daily sugar limits in a single serving. SUBSTANCE ANALYSIS Every scan breaks down flagged substances by severity — High Concern, Medium Concern, and Low Concern — with the specific research behind each flag. Red 40 is flagged because the FDA is actively phasing it out. Titanium dioxide is flagged because the EU banned it from food in 2022. The science is cited, not summarized. CLEAN ALTERNATIVES Every scan suggests cleaner alternatives with their own scores, descriptions, and links to purchase. Switching from M&Ms to Hu Chocolate Bar eliminates four petroleum dyes and drops your score from a 7 to a 2. VERIFIED CALIBRATION Over 3,500 products have verified calibration entries — meaning their score is locked by research, not estimated by AI. Centrum Silver is locked to a minimum of 6 because it contains FD&C Blue 1, talc, and titanium dioxide. Larabar is capped at 3 because it is a NOVA 1 whole food with two ingredients. The AI handles new and unknown products. The registry handles everything it has already verified. SCORE SCALE 1 to 2 — Safe. Clean ingredients, minimal processing, no flagged substances. 3 to 4 — Good. Conventional but no significant concerns. 5 to 6 — Caution. Real concerns worth knowing about. 7 to 8 — Switch. Known harmful substances or high processing load. 9 to 10 — Avoid. Confirmed harmful ingredients or banned substances. WHAT PARTIQULE IS NOT Partiqule is not influenced by brands or advertisers. It does not accept sponsored placements. It does not inflate scores for products with marketing claims like "natural," "clean," or "plant-based." A Beyond Burger scores a 5 because it is an ultra-processed NOVA 4 formulation regardless of its plant-based positioning. Free to start. No account required for your first scans. Unlimited scanning with a subscription. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is monetization model: Partiqule at free against StackFlow's free with in-app purchases. Partiqule also leads on iOS requirement (15.0 vs 17.6). On price, rating, review sentiment and ratings volume there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. StackFlow sells 2 in-app purchases, starting at $4.99 per month and Partiqule sells 1 in-app purchase, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for StackFlow against 5.0 for Partiqule. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews split almost evenly too, at 100% and 100% positive.
StackFlow ships an update every 2 weeks, Partiqule every 9 days. Both last shipped on October 2, 2026.
