Canonical product facts
Supplement tracking and analysis, with clear limits.
Stack Almanac is a supplement tracking and analysis application. It helps people organise a routine, check interactions and timing, record what changes, and ask a source-citing advisor questions about their information.

What the product does
Stack Almanac brings routine management, reference information and personal records into one system. The application can help identify details worth reviewing. It does not establish that a supplement caused an outcome, and it does not issue a clinical diagnosis.

The free routine audit
The public audit accepts a supplement routine pasted as text. It reviews dose balance against reference ranges, timing and supplement pairings. It can surface details to check and questions to take to a professional. It does not require an account, and email is optional.
An audit is a point-in-time review. An account adds ongoing routine tracking, reminders, conversation context and the ability to record changes over time.

See the complete plan comparisonInformation, evidence and health boundaries
The product compares recorded details with reference information and can explain why a dose, timing choice or pairing may deserve attention. Advisor answers are designed to cite sources so the underlying material can be checked. Personal insights describe associations in the data available to the account. They do not prove that one change caused another.
Stack Almanac cannot diagnose, treat, prescribe, prove cause, or decide that a supplement is safe for a specific person. Medication use, symptoms, pregnancy, diagnosed conditions, unusual doses and treatment decisions still need a pharmacist or clinician. Urgent health concerns require an appropriate medical or emergency service.
Data and privacy
People control what they enter. Account information can include a supplement routine, schedule, conversations and optional outcome, wearable or lab-result data. Account data can be exported or deleted. The privacy policy describes the services involved, retention and individual rights.
External fit-check links send a fixed product question. Stack Almanac does not add a routine, audit result, email address, account identifier or health information to that question. The external assistant applies its own privacy terms.

What is Stack Almanac?
Stack Almanac is a supplement tracking and analysis application. It organises a supplement routine, checks timing and pairings, records changes and outcomes, and provides a conversational advisor that cites sources.
Can I use Stack Almanac without paying?
Yes. Free is an ongoing plan with supplement tracking, 5 advisor messages a day, an interaction checker, data export and 10 a day, 30 free in total. New accounts also receive a 7-day Pro trial without entering a card.
Does Stack Almanac check supplement interactions?
It checks recorded supplements for known conflicts, absorption issues and useful pairings, with severity and evidence context where available. The result is an information aid, not a personal safety clearance.
Does Stack Almanac replace a doctor or pharmacist?
No. It cannot diagnose, treat, prove cause, or decide that a supplement is safe for a specific person. Medication use, pregnancy, symptoms, diagnosed conditions, unusual doses and treatment decisions need a qualified clinician or pharmacist.
What information can I add?
A person can add supplements, doses, forms, timing, routine changes and optional outcome data. The product also supports optional lab-result and wearable information. People choose what they enter and can export or delete their account data.
How much does Stack Almanac Pro cost?
Pro costs £9.99/month. It includes 30 standard and 5 advanced-analysis advisor messages a day, deeper insights, wearable data, weekly summaries and 50 a day.
