The GLP-1 companion built around protein, not weight

Sustain is a companion app for people on Ozempic, Wegovy, Zepbound, and Mounjaro. Most trackers in this space are built around weight. Sustain is built around protein instead, since losing muscle along with fat is what GLP-1 patients worry about most. Point your camera at a plate for an instant protein estimate, track dose, weight, and side effects, and get a weekly AI recap. Manual logging is free forever.

Hey PH, maker here. Built this solo after noticing every GLP-1 tracker on the App Store was injection-first and scale-obsessed, while the actual GLP-1 communities online talk about muscle loss constantly. Went through two App Store rejections getting the subscription disclosure and the medical framing right, and just shipped a 2.0 with real account sync and a proper in-app camera for the photo-to-protein feature. Happy to answer anything, including what didn't work.

What do GLP-1 tracking apps get wrong?

If you've used a GLP-1 tracking app (Ozempic, Wegovy, Zepbound, Mounjaro, whatever), what made you stop using it, or never start? For me it was that every app I tried was scale-obsessed and injection-first, while the actual conversation in GLP-1 communities is constantly about muscle loss, not just weight loss. That gap is what I built Sustain around.

Curious what's missing or broken in the ones you've tried, good or bad, happy to hear it before launch day.
