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 45+ built-in medications
- Don't want to enter medication data manually: Dose Track - native database with validated PK parameters

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.
