Shotsy alternatives: an honest comparison
Stay with Shotsy if you take a single branded pen and want the most-tested option in the category. It holds 4.84★ across 28,063 ratings, which is real evidence that the fundamentals work. Look elsewhere if you reconstitute vials, take peptides alongside your GLP-1, or want the dose countdown on your Lock Screen.
When to stay with Shotsy
The category's scale leader by a wide margin. GLP-1 first: no reconstitution calculator is advertised, and its own site describes injection-site rotation with next-site suggestions. Switching trackers means leaving your dose history behind, so a small feature gap is rarely worth it. The reasons that genuinely justify a move are structural: your medication does not fit the app's model, or a capability you need every week simply is not there.
When another app fits better
- You reconstitute vials. Shotsy does not advertise a reconstitution calculator. Bo, PeptidePal, Pep AI, Regimen and OptiPin do.
- You take peptides alongside a GLP-1. GLP-1-first apps are built around one branded medication; peptide-first apps expect several compounds on different schedules.
- You want to pay nothing. Injectly and Glippy advertise no in-app purchases at all.
- You want sourced estimated levels. Bo publishes the half-life and time-to-peak behind every curve with a link to the FDA label or study, and marks where human data is limited. See the chart.
The comparison
A checkmark means the feature is advertised by the developer; a dash means it is not advertised, which is not proof of absence.

About Bo
Bo is my app, so here is the honest shape of it: it is built for people reconstituting vials who also want food and weight in one place, it has a free calculator and free estimated levels, and it has no cloud sync and no Android version. If either of those is a dealbreaker, Shotsy or one of the others above is the better choice, and I would rather say so than have you find out after switching.
