Log GLP-1 doses
Log every dose, injection or pill, and get a reminder when the next one is due. Bild Health estimates how much medication is in your body with a pharmacokinetic model of your own doses, and shows it at the top of your week, above protein, water and training.
Lose the fat. Keep the muscle.

Up to 39% of the weight lost on a GLP-1 is muscle.
You can lose weight and keep your muscle, and some people even build it. It takes lifting heavy and eating plenty of protein.
Getting ~150 g of protein while eating 1,800 calories is HARD.
Bild Health makes it EASY.
Where your medication is, day by day.
A GLP-1 level climbs after each dose and falls until the next one, so no two days of your week start from the same place. Bild Health models that rise and fall with pharmacokinetics: each medication's published half-life and absorption time, applied to the doses you actually logged. The estimate leads the Week tab, with your protein, water and training for the same seven days below it.
- Dose reminders at the time you choose, kept on home time when you travel
- Zepbound, Mounjaro, Wegovy, Ozempic and more, injection or pill, with injection-site rotation
- Estimated medication level from a pharmacokinetic model of your own doses
- Week: the level card first, then protein, water and training for the same days
- An educational estimate, not a dosing tool and not medical advice

More features to help you hit your goals
Track fat and muscle
Fat mass and lean mass charted as two separate lines, from a body-composition scale through Apple Health and Health Connect and from imported DEXA scans.

1-tap protein logging
Four quick-add chips sized to real food. One tap logs a meal, and the same four sit on your watch.

Import DEXA scans
Connect BodySpec or upload a report PDF, and every scan lands on the same chart as your daily readings.

Sources and methodology
On the evidence. No randomized trial has tested sleep, protein or training in people taking a GLP-1 specifically. The evidence comes from energy-deficit studies generally, which is exactly why measuring your own result matters. The protein figures come from controlled energy-restriction work in populations that were mostly younger, often trained and often male.
How body composition is measured. From a body-composition smart scale synced through Apple Health and Health Connect, with DEXA scans as checkpoints, imported from a connected BodySpec account or a report PDF from any provider. The scale supplies cadence and the scan supplies the anchor.
On the medication level. The estimate applies published half-life and absorption data for your medication to the doses you log. It measures nothing in your body, it is not a dosing calculator, and nothing in Bild Health should be used to decide what or when to take. That is between you and your prescriber.

Know what you are losing.
Bild Health keeps fat mass, lean mass, protein, training and your dose history in one record. The lean number is measured from your scale, anchored by imported DEXA scans.
