Tracker

GLP-1 weight tracker

A single morning reading is mostly noise — fluid, food, timing. What is actually informative is the trend, and what makes the trend legible is knowing what else was happening that week. Cafeity records measurements alongside doses and meals, and refuses to turn any of it into a forecast.

Trend over reading

Cafeity shows the direction of travel rather than treating each morning as a result. Day-to-day variation can be substantial for reasons that have nothing to do with fat mass — hydration, salt, what time you weighed, where you are in the cycle — and a chart that reacts to every one of them teaches you the wrong thing.

The practical consequence is that the app is unhelpful to check obsessively, which is intentional.

Measurements, not just the scale

Waist and other measurements are recorded too, because weight alone is a poor description of a period where the stated concern is usually keeping lean mass. It is the same reason the nutrition side is protein-first.

Two people losing the same number of kilograms can be having quite different experiences, and the scale alone cannot tell them apart.

What it will not do

Cafeity does not predict how much you will lose or when, does not accept a weight goal below a BMI of 18.5, and does not set a calorie target below 1,200 kcal. Weight-loss apps routinely do all three.

These are hard limits rather than settings. Appetite suppression makes very low intake easy to reach accidentally, and a projection chart on a medication whose response varies widely between people is a promise nobody is in a position to make.

Plateaus are data, not failure

A flat stretch is a normal feature of the record. The app describes it and shows what else was happening around it — protein, hydration, symptoms, dose changes — without editorialising, congratulating or nudging.

There is no streak to break and no encouragement to earn. The record is meant to be something you can look at honestly on a bad month.

What the record holds

Every entry below sits on one timeline, so any of them can be read against where you were in the medication cycle when it happened.

  • Doses — date, time, the amount you were prescribed, and the medication as a plain label.
  • Injection site, on a body map, so rotation is visible rather than remembered.
  • Meals, with protein, fibre and hydration derived from what you logged.
  • Symptoms, in your words, with your own severity rating.
  • Weight and measurements, shown as a trend rather than a daily verdict.

Across every medication

This works the same way whichever medication you are on — the only thing that changes is the half-life behind the curve.

  • Semaglutide — once weekly, published half-life about 7 days (roughly 165 hours).
  • Tirzepatide — once weekly, published half-life about 5 days (roughly 117 hours).
  • Liraglutide — once daily, published half-life about 13 hours.
  • Dulaglutide — once weekly, published half-life about 4.7 days (roughly 112 hours).
  • Exenatide — twice daily, or weekly in the extended-release form, published half-life about 2.4 hours for the immediate-release form.

Where your data lives

On your device and in your own account, under per-record permissions. Health data is never stored in iCloud, never sold, never used for advertising, and never used as training data.

You can export everything in one file at any time, and you can delete the record entirely. When you want to bring something to an appointment, the Visit Summary builds a one-page, print-ready PDF from a period and the sections you choose — and nothing leaves the phone until you do that yourself.

What Cafeity will never do

  • Recommend, calculate or adjust a dose, or tell you when to take one.
  • Interpret a symptom, name a condition, or suggest what is causing something.
  • Predict how much weight you will lose, or when.
  • Set a calorie target below 1,200 kcal, or a weight goal below a BMI of 18.5.

Cafeity is a general wellness product. It does not diagnose, treat, cure, mitigate or prevent any disease or condition. Questions about your treatment belong with a licensed healthcare professional.

Common questions

Will it predict my weight loss?
No. Predicting an outcome is a hard limit. The app describes what has happened; it makes no claims about what will.
Can I set any goal I want?
Not any. Cafeity will not accept a weight goal below a BMI of 18.5 or a calorie target below 1,200 kcal.
Do I have to weigh myself daily?
No. Log at whatever frequency you and your clinician think is useful — the trend tolerates gaps.
Does it connect to Apple Health?
Cafeity is built around its own record so that the export is complete and portable. Health data stays out of iCloud regardless.
