Shotsy tracks your shots.
Bild Health tracks your muscle.
Shotsy focuses on your GLP shots, timing, location, side effects, and tracking overall weight loss. If you’re primarily trying to chase down negative side effects based on dosage, Shotsy is the better choice.
If you are concerned about weight loss AND muscle loss, Bild Health is for you. We center you on muscle-preservation goals with protein targets, lean mass & body fat tracking and more.
Feature by feature

How the rows are scored
Why these rows decide it, with the trials behind each one: The Science.
Shotsy’s v3.2.0 release notes (28 April 2026) list body fat and lean body mass among metrics you can enter, so those fields exist. We score them as a cross because a value you type in and never see charted is not tracking — we installed the app on 31 July 2026 and there is no lean-mass trend to read them against. Hydration is imported from Apple Health without a target, and is scored the same way. Everywhere else a cross means the feature is absent from what Shotsy publishes, which is not proof the app cannot do it.
Checked August 24, 2026. Every claim about Shotsy on this page comes from Shotsy’s own published feature and pricing pages, read on that date, with the one exception noted above. Products change; if something here has gone out of date, tell us and we’ll correct it.

Up to 39% of the weight lost on a GLP-1 is lean mass, not fat.
There is a narrow path to losing weight and keeping or even gaining muscle. To do so you must lift heavy and consume a ridiculous amount of protein.
Track Protein in 1-Tap.
Consuming 140–180g of protein a day is very hard. Bild Health makes it easy to track how much you consumed each day with simple 1 tap logging for protein, hydration, and exercises. You can also track from your Apple Watch. Start with the free protein calculator.
Track Weight and Muscle
Bild Health integrates with smart scales to help you track not just your weight but your lean mass as well, track both together and adjust your exercise and protein intake based on your results. See what the split looks like with the muscle-loss calculator.
Import Your DEXA Scans
Smart scales are good, but the reference most of them are checked against for body fat and lean mass is the DEXA scan. Bild Health imports your scan results and adds these to your charts beside your scale readings, giving you more data on your fat loss progress. More on how the two compare in DEXA scans vs. smart scales.
Shotsy alternatives, answered
Is Shotsy free?
No. The features it's known for sit behind Shotsy+, which runs $39.99–$59.99 a year depending on the offer you're shown.
Does Shotsy set a protein target?
Not that Shotsy describes. Its materials present protein as a number imported from Apple Health and displayed alongside the rest of your record; nothing in them describes a target being set, personalized or coached. That is absence from the vendor's own account rather than proof of absence. Bild Health computes a protein target against your measured lean mass and moves it as that number moves, which is a different job from showing you what you ate.
Does Shotsy track body fat and lean mass?
Since version 3.2.0 (April 2026) the fields exist: values you can enter. What we could not find in the running app on 31 July 2026 is a lean-mass trend: the value is stored, never drawn as a line. That line is the whole reason Bild Health exists.
Does Shotsy sync with a smart scale or import DEXA scans?
Nothing Shotsy publishes describes either: its Apple Health section names weight, calories, protein and water. That is absence from the vendor's account, not proof the app cannot. Bild Health reads fat and lean from a body-composition scale through Apple Health, anchored by imported DEXA scans.
Can I use Shotsy and Bild Health at the same time?
Plenty of people will: keep the deep medication logbook where it is deepest, and the composition record where it is measured. Bild Health logs doses, food and protein as well, so it also works as the only app on the phone. The only thing worth avoiding is keeping two authoritative dose histories, since reconciling them later is miserable. Pick one app as the record of the shot.
Keep the shot log. Add the muscle.
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.
Lose the fat. Keep the muscle.
