Compare · GLP-1 injection tracker
VialBook vs Shotsy.
Shotsy is one of the most polished GLP-1 injection trackers, with a strong multi-metric chart. VialBook takes a wider, more private approach: one app for TRT, peptides, GLP-1, supplements, and labs, with the data kept on your device. Here is an honest, side-by-side look so you can pick what fits.
- A genuinely good multi-metric chart for weight and dose over time
- Clean, focused experience for people who only run a GLP-1
- Home-screen widget for the next shot
- One app for the whole stack
Shotsy is GLP-1-focused. VialBook tracks TRT, peptides, GLP-1, supplements, and labs in one timeline, so you aren't juggling apps if you run more than one thing.
- Reconstitution math built in
VialBook computes draw volume and U-100 units from your vial and BAC water inside the dose logger. A lyophilized GLP-1 vial reconstitutes the same as any peptide, and the math is shown with no rounding.
- Private by default
Shotsy syncs to the cloud. VialBook keeps your data on your device by default, with no account required and a one-tap wipe. Nothing is sold.
- Free to start
VialBook's free tier tracks up to 3 active compounds forever. Paid unlocks unlimited compounds, the cross-stack timeline, and export.

If you only run a GLP-1 and like a cloud-synced, chart-first app, Shotsy is a strong pick. If you run more than one thing, want the reconstitution math built in, and want your protocol data to stay on your device, VialBook is built for that.
FAQ
VialBook vs Shotsy, answered.
Is VialBook a good Shotsy alternative?
Yes, especially if you want more than GLP-1 tracking, want reconstitution math built in, or want your data to stay on your device instead of syncing to a cloud account. Shotsy remains a strong choice for a GLP-1-only, chart-first experience.
Does VialBook track GLP-1 like Shotsy?
Yes. VialBook tracks GLP-1 doses, sites, weight, and labs, and adds reconstitution math for lyophilized vials. It also covers TRT, peptides, and supplements in the same app.
Does VialBook sync to the cloud?
No. VialBook is on-device by default, with no account required. That is a deliberate difference from cloud-synced trackers. Your protocol data stays with you.
