Bo is an iOS app for people on GLP-1 medications and peptide protocols.

It does your reconstitution math (U-100, U-40 and tuberculin syringes), reminds you when a dose is due, remembers where you injected last time on a tap-anywhere body map, and models your estimated medication level between doses using half-life data from FDA labels and published studies. It also scans meals from a photo, scores them for someone on a GLP-1, and answers questions through Ask Bo, an AI chat that knows your own doses and meals.

GOOD TO KNOW iPhone and iPad only, no Android yet. Data is stored on your device, so it does not transfer to a new phone. Bo is a tracking and calculation tool, not a medical device, and does not give medical advice.
