What is Stack Almanac?

Stack Almanac is an AI-powered supplement advisory platform that learns what works for your body. It combines a conversational AI advisor, personal insights, and personalised recommendations to help you optimise your supplement routine with data.

How much does Stack Almanac cost?

Stack Almanac is free to use with 3 AI advisor messages per day. Pro costs £7.99/month and includes 30 Sonnet + 5 Opus messages per day, advanced analytics, and personalised recommendations. Every new account starts with a 21-day Pro trial, no credit card required.

How is Stack Almanac different from other supplement trackers?

Stack Almanac's unique advantage is personal insights that learn from your data over time, not generic literature. It connects what you take to how you feel, with personalised recommendations based on your biology, goals, and health metrics.

What is the consistency card in the Restock section?

It shows your personal take rate for a supplement over the past six weeks. Stack Almanac calculates it from your daily logs, so the number reflects how consistently you have actually been taking it, not just what you intended.

How do I turn on push notifications for restock alerts?

Open Settings, go to Notifications, and enable Restock alerts. You can also toggle alerts for individual supplements from their detail screen. Restock push notifications are available on the Pro plan.

How does Stack Almanac know which region to show offers for?

It uses the country you set in Profile settings. You can also change region directly from the Restock card without going back to settings. Partners are filtered to UK, US, EU, or Global based on your selection.

What happens if I scan multiple bottles at once?

Bulk scans using Add all apply a suggested days-supply figure automatically based on the serving size on each label, with no extra prompts. Single scans show a quick-select so you can confirm or adjust.

Restock smarter: alerts, impact data, and regional pricing

Push alerts when supplements run low, a consistency card before you restock, regional partner pricing, and a shareable shopping list.

product releases

Stack Almanac now shows you your own consistency data before suggesting a restock, sends push notifications when supplements run out, and routes you to the best-priced partner in your region. This update also adds a shareable shopping list and auto-suggests how many days supply to log when you scan a new bottle.

Know what has been working before you restock

A new card appears in the Restock section for any supplement you have been taking consistently. It shows your actual take rate over the past six weeks, your star rating if you left one, and a direct link to buy more. The card only appears once you have 14 or more logged doses, so the data behind it is meaningful.

If you are below the threshold, a small progress bar shows how close you are to unlocking it. No pressure, just a nudge to keep logging.

Push notifications when supplements run low

Pro subscribers now receive a push notification when any supplement reaches Critical or Depleted status. Notifications are per supplement, deduplicated over seven days, and respect a quiet window between 10pm and 7am. You can toggle alerts for individual supplements directly from the supplement detail screen.

Regional pricing

The Restock section now filters offers by your region. Set your country in Profile settings and Stack Almanac will show UK, US, EU, or global partners accordingly. A region picker also appears inline on the Restock card so you can switch without leaving the screen.

Shareable shopping list

Tap the share button on the Restock card to share your current restock list via the system share sheet. On browsers without share support, a drawer opens with a copy-to-clipboard option.

Days-supply capture when adding supplements

When you scan a single supplement barcode, a quick prompt now asks how many days supply the bottle contains. Tap one of the quick-select options (30, 60, 90, or 180 days) or let Stack Almanac suggest a number based on the serving size on the label. Bulk scans use the suggested default silently, with no extra taps.

Restock section in the weekly digest

The weekly email digest now includes a Time to Restock section listing any supplements at low, critical, or depleted status, with a direct buy link for your region. You can disable this section in Notification settings if you prefer.

Admin tooling for the affiliate programme: partner rows in the admin panel now show a direct link to join each retailer's affiliate programme, an amber badge where an affiliate tag is still missing, and an editable field for programme signup URLs. This is internal tooling — nothing changes for users.
