Build a supplement routine you'll actually keep. Tell fillin what you want in plain language—"I want to sleep better and feel less stressed"—and get a stack of nutrients, products and daily check-ins for that goal. Then track it in one place, every day. WHY FILLIN Most people take supplements without knowing what they take, why, or whether it helps. fillin turns that into a routine you can see: what's in your stack, what you took today, and how you feel over time. BUILD A STACK FROM ONE SENTENCE Describe your goal. fillin proposes ingredients with doses, products that cover them, and the check-ins that matter for that goal—each with its sources. Review, adjust, and create your stack in seconds. MORE THAN ONE STACK Sleep, training, focus—keep a separate stack for each goal, with its own supplements and tracking. Today rolls them all into one daily view. TODAY, IN ONE VIEW Check off what you took. Log how you feel on a simple 1–5 scale. One progress ring shows where you stand across all your stacks. KNOW WHAT YOU HAVE Items keeps your products in two lists—already have and to buy—and adds up ingredients across your stacks so you don't double up. FIND AND COMPARE Search supplements by need or ingredient and compare products before you buy. Purchases happen outside the app. INSIGHTS As you track, fillin builds reports that connect your routine to how you feel—so you can see what's working and what isn't. APPLE WATCH (OPTIONAL) Wear an Apple Watch to sleep and fillin can read sleep and activity data from Apple Health to show passive trends on Today. Read-only, clearly labeled, and entirely optional. fillin is a wellness and organization tool. Its suggestions are general information, not medical advice. It does not diagnose or treat any condition—always consult a qualified professional about your health and any supplements you take.

Build a routine that actually sticks, get reminded until you log it, and never run out of what matters. BUILT FOR YOUR STACK Track vitamins, minerals, protein, and pre/post-workout supplements alongside prescriptions and OTC meds — all in one place Schedule doses by specific times, fixed intervals, selected weekdays, on/off cycles, or as-needed (PRN) Smart reminders repeat until you actually log the dose — not just once Track pills/servings on hand and get a refill nudge before you run out Start fast with ready-made stacks (Morning Energy, Sleep & Recovery, Immunity Boost, Pre-Workout Performance, Post-Workout Recovery, Joint & Mobility Support) or build your own from scratch See your adherence over time and export a clean PDF report to share with your doctor or coach Snap a photo of the bottle or pill so you always grab the right one WHY IT WORKS Most supplement routines fall apart because there's no system — SuppTrack gives your vitamins, protein, and pre/post-workout stack the same structure a pill organizer gives medication, so taking your supplements becomes a habit instead of a guess.
