OnDose vs SelfAssay

Know what you're taking. OnDose organises your supplements by timing and absorption, flags interactions from published research, and tracks what you take each day. Not medical advice. Just clarity. — SEE HOW THEY INTERACT Add a supplement and instantly see what competes, what combines well, and what to separate. Every interaction in your stack is checked against published research. Severity levels from Info to Avoid, each with a cited source. Zinc blocks iron. Calcium competes with magnesium. Your morning stack might be cancelling itself out. OnDose catches it. — GET YOUR TIMING RIGHT Supplements are grouped into timing windows based on absorption science. Iron on an empty stomach, magnesium in the evening, competing minerals separated by two hours. OnDose builds your daily schedule so you don't have to think about it. — DAILY CHECK-IN Your daily schedule shows what to take and when. Check off each supplement as you go, build a streak, and look back at any day to see exactly what you took. Push notifications at each timing window keep you on track. — SCAN. DON'T TYPE. Point your camera at a product's UPC barcode. OnDose checks against 37,000+ supplements from DSLD, Open Food Facts, and major brands. Name, dose, and ingredients fill in automatically. Not in the database? Photograph the Supplement Facts label. Ingredients, doses, and serving size are extracted automatically. — ORGANISE YOUR STACK Add supplements, set doses and timing, and keep your full routine in one place. — YOUR DATA, ALWAYS Export your full supplement history, check-ins, and stack configuration as JSON or CSV. No lock-in. If you leave, your data leaves with you. — WHAT'S INSIDE • 350+ supplement compounds covered • 100+ interactions checked with cited sources • 37,000+ barcodes indexed • Timing recommendations based on absorption science • Daily check-ins with streak tracking • Push notifications for each timing window • Barcode scanning and label photo OCR • Full data export (JSON/CSV) — ABOUT THE DATA Interaction data is sourced from NIH Office of Dietary Supplements, EFSA, and peer-reviewed journals. Every interaction cites at least one published source. Absence of data is shown as "no known interaction data available," never as "safe." This app is for educational purposes only. It is not medical advice and does not diagnose, treat, cure, or prevent any disease. Always consult a qualified healthcare professional before making changes to your supplement regimen. — SUBSCRIPTION OnDose requires a subscription to use. 3-day free trial, then auto-renews monthly.

SelfAssay is a research workspace for people who self-experiment with supplements, peptides, and nootropics. Look up the evidence, then find out with your own data whether your stack is actually working for you. IMPORTANT SelfAssay is decision support for your own research. It is not medical advice and does not diagnose, treat, cure, or prevent any disease. It does not sell, source, or recommend any compound, and it does not encourage the acquisition or use of any substance, including prescription or research compounds. Always consult a qualified clinician and follow the laws where you live. LOOK UP ANY COMPOUND Search a growing index of 500+ compounds. Each dossier shows an effectiveness grade by purpose (sleep, focus, recovery, fat loss, and more) and a separate safety grade, both computed from thousands of classified first-hand community reports. See the most-reported effects and side-effects, cited studies and clinical trials, and clinical biomarker directions. When there is not enough first-hand data yet, you see a dash. We never guess. TRACK YOUR OWN STACK Log the compounds you take with dose and schedule, run daily check-ins for energy, focus, mood, and sleep, and set up simple n-of-1 experiments. Connect Apple Health to layer your sleep, HRV, and resting heart rate onto the days you took a compound versus the days you did not. The correlation is computed entirely on your device. MORE TOOLS - Companion: an AI assistant for compound questions, grounded in the dossier data so it refuses rather than fabricates. - Pre-Flight: surfaces interaction and safety considerations reported in the community and the literature for a planned stack, as information to review with a qualified clinician. - Decoder: organizes the values from your own lab report for your reference and lines them up against your stack. It does not diagnose or interpret your results. - Protocols: save and revisit structured protocols. PRIVATE BY DESIGN Your vault is encrypted at rest. Apple Health data stays on your device and is never sent to our servers. There is no third-party analytics and no tracking. Export or permanently delete your account and data anytime from the app. FREE TO USE Core research and tracking are free to use. Companion, Pre-Flight, and Decoder have free limits, and advanced use is part of SelfAssay Pro.
