Your body keeps a record too
The Body log shipped in 1.9: bathroom breaks, how you feel, supplements and your cycle, one tap each, sitting next to your meals. Built for people whose medication changes more than their appetite.
If you’re on a GLP-1, the food log is only half of what you need to see. The other half is what your body did about it — the days nothing moved, the days everything did, the week the nausea lifted, the stretch where you felt fine and forgot you were on anything at all.
People were already tracking that. In a notes app, on paper, in their head badly. So in 1.9 we built it into the app, next to the meals, where it can actually be read against them.
What it is
Four sections, each one tap from the Today screen:
- Bathroom break. Both kinds. Bristol scale if you want it, ease and amount if you want them, nothing required.
- How I feel. A short list of the symptoms that actually come up on these medications, plus a note field.
- Supplements. A checklist of what you take, ticked off as you take it.
- Cycle. Period days, logged plainly.
You switch on only the sections you want. Bathroom and How-I-feel are on by default because they’re what most people came for; cycle is off until you turn it on. The ones you don’t use stay invisible — no empty cards reminding you of a feature you declined.
What it deliberately doesn’t do
There is no gut score. No streak. No “you haven’t logged a bowel movement in 3 days” notification. Nothing is graded, and nothing here feeds a number that judges your week.
That restraint is the whole design. The value of this data is that you’ll actually enter it, honestly, on a bad day. Anything that makes a bad day feel like a failed day gets that data deleted or fabricated, and then it’s worth nothing to you or your prescriber.
It also stays firmly on the passive side of a line we hold: Macroline records what you tell it and shows you the patterns. It does not interpret symptoms, suggest a dose, or tell you what any of it means medically. That conversation belongs to you and your clinician, and the log exists to make it a better conversation.
Why it sits next to the food
Because that’s where the pattern is. Three low-protein days in a row and a rough Thursday is a thing you can see on one screen, and it’s the kind of thing worth mentioning at an appointment — not because the app drew a conclusion, but because you can point at the week.
The diary shows it inline with your meals. History shows it over time. And if you’ve connected Claude, it can log any of it by voice while you’re doing something else: “log a bathroom break, normal” while you’re washing your hands beats opening an app.
The privacy part, plainly
This is the most sensitive data in the product, and it’s treated that way. It’s named explicitly in our privacy policy rather than buried under “health data”. It isn’t sold, it isn’t used to train models, and deleting your account deletes it — the bathroom log, the symptoms, the cycle days, all of it, along with everything else.
If you’re on a GLP-1 and you’ve been keeping two records — one in a tracker and one in your head — this is us trying to end that.
