Exactly the app I needed as a college student

I’ve tried a few GLP-1 apps and this is the first one I’ve actually stuck with. Love how easy it is to track my shots, water, protein, and food without spending forever logging everything. The little widgets are super cute too. Makes staying consistent way easier.
