Matched from 17,000+ products. Each need gets a product chosen by quality score and buyers' ratings, scheduled at one serving from its label.
A reason for every product. Each item says why it's there and why at that time; “About this routine” covers priorities, your shelf, what's new and what was left out.
Timed for your day. Morning, noon, evening or bedtime, with a short instruction such as “with dinner”.
Review when things change. When your goals or shelf change, the app suggests a review; you choose whether to rebuild. Earlier routines stay in history.
Add or edit anything yourself. Add any product, set its part of the day, repeat days and amount per take, or remove it.

Supply counts. How many are left in each bottle, counted down as you take them, with roughly how many days remain.

Reminders per part of the day. Your own time for morning, noon, evening and bedtime; skipped when you've already marked everything.

Knows your routine and shelf. Answers draw on your answers, routine, shelf, what you've taken and the catalog, and show the steps taken.
Photos and PDFs. Attach a photo or PDF, such as a label or a lab report, and get it explained in plain language; nothing is stored.
Product cards and follow-ups. Products appear as cards you can open, with suggested next questions under each reply.

Conversations. Keep several conversations, go back to earlier ones, or clear one to start fresh.

Safety rules. Pregnancy, medication, condition, allergy, diet and upper-limit checks before anything is suggested; some products are marked “Review with a professional”.
