Safer advisor suggestions, plus a smarter weekly digest

Stack Almanac just got two upgrades aimed at the same thing: making suggestions you can act on with one tap, without second-guessing them. The Almanac Advisor now refuses to add or move a supplement that clashes with your diet or allergies, and the weekly digest now shows week-over-week trends for each of your health metrics, with a personalised insight for Pro subscribers.

What happens if I tap to add a supplement that clashes with my diet?

It will not be added. When you ask the Almanac Advisor to add or move a supplement and tap to apply, it now checks the supplement's ingredients (including different forms of the same supplement, like lichen-derived versus lanolin-derived vitamin D3) against your diet and your allergies before saving anything. If something clashes, it blocks the change and offers a suitable alternative instead. No more discovering after the fact that the fish-oil capsule the advisor mentioned in passing has actually landed in your stack while you are vegan.

This sits on top of the existing rule that the advisor should not recommend things that clash with your diet in the first place. The new check is the second layer: even when a suggestion slips through, the apply step holds the line. If the app cannot read a supplement's ingredients or your bio profile for any reason, the add is blocked with a "couldn't verify" note rather than letting it through. Safer to ask twice than to add the wrong thing.

What changed in the weekly digest?

Two things. First, every health metric in the digest (sleep, HRV, resting heart rate, your outcome scores) now shows a this-week-versus-last-week delta, so you can see at a glance whether things are trending in the right direction without having to remember last week's numbers. Sleep duration in particular now reads correctly, in hours and minutes, instead of as a raw figure that was easy to misread.

Second, Pro subscribers now get a personalised two-sentence insight from the Almanac Advisor at the top of the digest. It looks at your week, picks out the one thing worth noticing, and says it in plain English: a metric that moved, a supplement worth reconsidering, a streak worth keeping. One paragraph, one decision.

What about the Memory page?

The Memory page from last week's release (what the Almanac Advisor knows about you) now lets you edit a saved fact inline, instead of having to delete and re-add it. And a daily background pass merges near-duplicate facts so the list stays tidy, even if you have told the advisor the same thing a few different ways over time. Less manual housekeeping, same full control.

Do I need to do anything?

No. The diet and allergy check is on by default and applies as soon as you update the app. If you have not set your diet or allergies yet, this is a good moment to add them in Bio Profile so the advisor has something to check against. The weekly digest changes show up in the next Sunday email. The Memory page changes are live now.
