What you get
Two products, one ingredient, so you know what to review next.
Sample data. What day one looks like from a pasted list.
02 · Observe, then decide
Keep the record and the next question together.
See what was recorded, what may be forming and what still needs more time. Then ask the Almanac Advisor with that context in view. A pattern is something to revisit, not proof of cause.

Today
See what changed, and what the record can support.
- Observed
- Enough of your own record to show a pattern worth reading.
- Emerging
- A pattern may be forming. Keep the routine steady.
- Too early
- Useful context, but not enough to draw a conclusion.
Almanac Advisor
Ask a better question with the full record in view.
The Advisor uses the supplements, goals and observations you choose to save. It cites sources, gives you one practical next step, and flags questions that belong with your GP or pharmacist.
Free to start. Pro only if it earns its place.
7 days of Pro, no card. On day 8 you move to the free plan and pay nothing.
Free plan: 5 Advisor messages a day and bottle scans (10 a day, 30 free in total).

Overlaps, timing, cost, check-ins, blood results, 5 Advisor messages a day and bottle scans (10 a day, 30 free in total)

£9.99 a month: 30 standard and 5 advanced-analysis messages a day, bottle scans (50 a day), Oura sync, Stack Impact and a doctor PDF
Questions people ask before they start.
- Do I need a wearable?
- No. Daily check-ins on sleep, energy and focus are enough for your record to compare days on and off a supplement. If you do have one, Apple Health comes in free through an iOS Shortcut (steps, sleep, resting heart rate, blood pressure and body weight), and Oura syncs on Pro.
- Will it tell me to stop my medication?
- No. Stack Almanac is a personal record and reference tool for adults who take supplements. It does not diagnose, treat or advise on medical conditions, and nothing in it is a reason to stop a medicine. Don't stop or change anything your GP or pharmacist prescribed. The Advisor tells you when a question is one for your GP or pharmacist.
- What happens after the trial?
- On day 8 your account moves to the free plan and nothing is charged. You never gave a card, so there's nothing to cancel. Your list, check-ins and blood results stay. The free plan keeps 5 Advisor messages a day and bottle scans (10 a day, 30 free in total). Oura sync, Stack Impact and the doctor PDF are Pro, at £9.99 a month if you choose it.
Start the next decision with the routine you already have.
