AI Peps is a private research log for tracking peptide research entries, reconstitution math, and personal schedules — built for biohackers, researchers, and self-quantifiers who want one organized place for their notes. Important: This app is provided for research and educational purposes only. It is not medical advice, not a diagnostic tool, and not a substitute for a licensed healthcare provider. The compounds referenced are research compounds and are not approved by the FDA (or equivalent regulators) for human use, treatment, diagnosis, or prevention of disease. WHAT YOU CAN DO • Schedule reminders — Set your own recurrence (daily, every-N-days, specific weekdays, weekly) and get reminders so you don't lose track of your research log entries. • Site rotation tracker — A visual body map for logging which site you used for each entry. Helpful for keeping your records organized. • Research literature library — Browse a catalog of 55+ research peptides with mechanism summaries, reported research ranges from published literature, and peer-reviewed citations linked directly to PubMed and journal sources. • AI insights — Optional pattern analysis across your own logged entries: adherence to your schedule, site rotation patterns, and research-log consistency. Insights are observations on your own data, not medical recommendations. • Apple Health integration — Optionally read weight and workout data from HealthKit to keep all your self-tracking in one view. • Private and secure — Your research log is stored privately in your account and never sold or shared. AI Peps includes auto-renewable subscription options for AI Peps Pro. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current billing period. Payment is charged to your Apple ID account at confirmation of purchase. You can manage or cancel subscriptions in your Apple ID account settings.
