Keep your supplements and peptide doses organized in one daily schedule. Log what you take, get reminders, and review your adherence, weight and wellness over time. YOUR DAY, TOGETHER See supplements and scheduled peptide doses in Today. Build a routine around your wake-up, meals and bedtime, then check off each dose as you take it. A RECORD YOU CAN REVIEW Explore dose history, adherence calendars and progress views. Record weight and wellness check-ins alongside your regimen to spot patterns. Patterns and correlations do not establish cause and effect. PEPTIDE TRACKING Keep records of your protocols, vial use and injection sites. Review past site usage to help plan rotation. Any estimated compound-level chart is illustrative and is not a measured blood level or a guide to when to take a dose. Follow your clinician's instructions. BUILD AND MAINTAIN YOUR STACK Find supplements in the library, add your own items, manage inventory and review supported timing checks. Checks are informational, are not exhaustive and do not establish that a combination is safe. REMINDERS AND WIDGETS Use reminders and supported Home Screen or Lock Screen widgets to keep your routine visible. Reminder timing follows the schedules you enter. BACKUP AND RESTORE Create a full backup in Files and restore your saved regimen and history when needed. Keep backups somewhere safe before replacing or deleting your app. OPTIONAL ONLINE TOOLS Label scanning and the AI Supplement Advisor use online processing. Relevant input is sent to service providers when you use these features. Core tracking records are stored on your device; analytics and subscription services also process data as explained in the Privacy Policy. SUBSCRIPTION ACCESS New users need a StackDay Pro subscription to continue after setup. Available plans, prices and any eligible free trial are shown before purchase. Subscriptions renew automatically unless canceled through your Apple account. Existing users may retain legacy access. MEDICAL DISCLAIMER StackDay is for personal organization and tracking. It does not provide medical advice, diagnose conditions, prescribe treatment or determine safe doses. Verify any calculations independently and consult your healthcare provider before changing a medication, supplement or peptide regimen.
