Fillin: Supplement Tracker

Fillin helps you build a supplement routine that fits your goals—and actually stick with it. BUILD YOUR STACK Tell Fillin your health goal and current state, and our AI suggests nutrients and supplements tailored to you. Start from a preset, get AI recommendations, or add your own—then organize everything by when you take it (morning, afternoon, evening). NEVER MISS A DOSE Set your own reminder times and get a gentle nudge at each time slot. Timing is everything with supplements—Fillin makes it effortless. TRACK WHAT MATTERS Check off what you took each day and see your progress. Over time, Fillin helps you understand your routine instead of guessing. SLEEP & RECOVERY (Apple Watch) If you wear an Apple Watch to sleep, Fillin can read your sleep and recovery signals from Apple Health to show daily Sleep and Recovery scores. This data is processed entirely on your device and is never sent to our servers or used for advertising. It's completely optional. INSIGHTS As you track, Fillin builds insight reports that connect your routine to how you feel and recover—so you can see what's working. Fillin is a wellness and organization tool. It does not provide medical advice, diagnosis, or treatment. Always consult a qualified professional about your health and any supplements you take.
