Protokol Lab vs
every other GLP-1 tracker.

Honest head-to-heads against every tracker in the GLP-1 space — iOS natives like Shotsy and MeAgain, free PWAs like Glapp and DoseDiary, and legacy calorie counters like MyFitnessPal and MacroFactor. Feature matrices, pricing, and a clear "use them if…" vs "use us if…" on every page.

What makes Protokol Lab different

Two things no other tracker in the space combines:

  • Pharmacokinetic dose modeling — Bateman-equation half-life curves for every built-in compound and any custom compound you add.
  • Rolling 7-day calorie budget — calories roll forward so low-appetite days after your shot don't read as failure.
  • 0–10 symptom severity — correlate nausea, fatigue, or injection-site reactions against your dose curve, not just a yes/no toggle.
  • Agentic AI — reads your full log, searches the web, creates custom foods, and writes entries into your day.
