2026 buyer's guide

Eight AI weight-loss apps, compared by how they help

The label “AI weight-loss app” covers very different jobs: proactive coaching, behavioral programs, tracking, communities, and photo estimation. Compare reproducible behavior rather than treating a feature checklist as proof of efficacy.

Start with the job you want the app to do

Glow is built for people who want the coach to initiate a voice check-in. Other apps may be stronger fits for database-led tracking, community, human coaching, or photo-first logging.

How to choose

Choose proactive contact only if you want it. Choose text for asynchronous reflection, voice when speaking is more convenient, and qualified care for diagnosis or treatment. Verify privacy, deletion, billing, and cancellation before subscribing.

Build a check-in rhythm that fits your day.

Glow AI Coach is a separate app subscription purchased through the Apple App Store or Google Play. It is not the separately enrolled and billed Endo Health GLP-1 clinical program or medical care.
