Store description excerpt
Most supplement apps are a checklist. Stackwise is the one that tells you whether any of it is doing anything. WHAT'S IN YOUR STACK, AND WHAT IT ADDS UP TO Scan a bottle and Stackwise pulls the actual supplement facts panel from the NIH's label database — not a guess, not a name match. It totals every nutrient across every product you take, so you find out that three of your products all contain magnesium and you're at 480mg without ever deciding to be. INTERACTIONS YOU'D OTHERWISE MISS Calcium blocks iron. Zinc depletes copper above 40mg. Several common supplements interfere with thyroid medication if taken at the same time. Stackwise flags these between the specific products you've added — no generic warning lists, no alarms about things you don't take. Each one explains the mechanism and how far apart to space them. WHAT'S ACTUALLY WORKING Rate your sleep, energy, focus and mood in a few seconds a day, or let Apple Health supply sleep, workouts, HRV and resting heart rate automatically. Stackwise looks for associations between what you take and how you feel. Here's the part other apps skip: when you test dozens of supplement-outcome pairs at once, some will look meaningful purely by chance. Stackwise corrects for that, and tells you how many associations it tested. If nothing survives, it says so. A tool that only ever finds good news isn't telling you anything. WHAT YOU'RE PAYING FOR Monthly cost per product, cost per serving, duplicate ingredients across products, and what you're paying for but not consistently taking. Most people find something to cut. BUILT TO STAY OUT OF THE WAY Four time slots, one tap to log. No streaks, no badges, no notifications guilting you about a missed dose. PRIVACY Your data stays on your device. There's no account, no sign-up, and nothing is uploaded. Health data is read only — Stackwise never writes to Apple Health, and never uses it for advertising. FREE AND PRO Free: up to 3 products, interaction checking, daily logging, 14 days of history. Pro: unlimited products, barcode scanning and label import, Apple Health, outcome analysis, and cost tracking. $29/year (first month free) or $3.99/month. Stackwise is an educational reference tool, not medical advice. Anything it flags is a prompt to talk to a pharmacist or doctor — not an instruction. SUBSCRIPTION DETAILS Stackwise Pro is $29/year (with a one-month free trial) or $3.99/month. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel any time in your Apple Account settings.
