About The Onset
Onset helps you organize and follow daily wellness routines in one place. Scan your supplement bottles, build a timed daily plan, log quick check-ins, and track what you take — on your schedule, the way you decide. KEY FEATURES: - Daily routine organizer — schedule supplements and wellness habits by time of day with timed reminders you set - Practitioner protocols — connect with your clinic using a personal connection code to import assigned supplement routines and optionally share adherence, labs, and check-ins you choose to disclose - Fitness routine organizer — arrange a weekly exercise plan by day and movement, import templates, or accept clinic-assigned routines alongside your supplement schedule - Bottle scanner — point your camera at a supplement label to identify the product and add it to your routine as an editable draft - Inventory tracking — track remaining supply for each supplement and receive on-device low-stock reminders - Lab result import — import lab reports and view values alongside your laboratory's reference ranges (display only; no interpretation) - Supplement reference library — view published information from NIH and CDC sources for supplements in your routine, including common dose ranges, timing notes, and known nutrient interactions, all with source citations - Quick check-ins — log sleep, energy, mood, and other wellness metrics on simple scales - Mode selection — choose Recovery, Performance, or Fertility (male) or Balance, Cycle Awareness, or Fertility (female) to frame your routine - Protocol Lab (Pro) — an interactive educational simulation where you create virtual characters, assign supplement protocols, and visualize how different combinations interact through animated gameplay - Cycle awareness — female users can track cycle phases and view how routines relate to their monthly rhythm - Trend display — view your self-reported check-in data over time as simple charts - Performance prep timer — countdown and checklist for pre-activity preparation - Completion tracking — see your daily adherence and streaks - Apple Watch companion and home screen widgets — view today's routine at a glance - Last1.id link (optional) — connect a portable identity in Settings to simplify sign-in across Last1 apps when you choose to link accounts Onboarding includes a biological-sex profile so mode options and routine framing match app settings. Users can update preferences anytime in Settings. Clinic connection: If your practitioner uses Onset Clinic, enter your personal connection code during onboarding or from the subscription screen to continue with your assigned protocol at no charge. Supplement and fitness imports appear in your library for you to organize and mark active. Onset is a wellness organization tool. It displays published reference information and user-entered data. It does not provide medical advice, diagnose conditions, or recommend treatments. Always consult a healthcare provider for medical decisions. SUBSCRIPTION: Onset Pro unlocks the bottle scanner, inventory tracking, Protocol Lab, additional modes, performance prep timer, routine reminders, and advanced organization tools. Pricing and terms available at checkout. Practitioner-assigned protocol items remain available without Pro. Privacy policy: https://theonset.app/privacy Terms of use: https://theonset.app/terms
