Best App by Use Case

  • GLP-1 only (Ozempic, Wegovy, Mounjaro): Shotsy — purpose-built with excellent GLP-1 level tracking
  • TRT only: TRT Plus — deep TRT focus with advanced PK modeling
  • Multiple medication types + AI: Dose Track — the only app with AI bloodwork analysis and 600+ built-in medications
  • Don't want to enter medication data manually: Dose Track — native database with validated PK parameters
  • DIY users who want full control: Regimen — enter your own formulas
  • One-time purchase (no subscription): TRT Plus

The Honest Bottom Line

There's no single "best" app — it depends on your needs:

  • If you only use GLP-1 medications, Shotsy is excellent and purpose-built for that.
  • If you only use TRT, TRT Plus offers the deepest testosterone-specific features.
  • If you use multiple medication types (TRT + peptides + GLP-1), Dose Track or Regimen are better all-in-one options.
  • If you want to scan bloodwork PDFs and correlate with dosing, Dose Track is the only option with on-device OCR.
