Is there a free GLP-1 tracker?

Yes, more than one. Glapp is currently free with no premium tier. Shotsy, Pep, and Mingo are free to download with optional premium features. Regimen is freemium, with a free tier (one compound) and a free trial before paid Premium. Phaze keeps its core free: dose logging for your first medication, the Estimated Levels chart, side-effect logging, weight, check-ins, meal logging by search, barcode, label scan and manual entry, four progress photos, the PDF report for your appointment, Apple Health sync, and widgets. The parts that cost engineering and per-scan compute, lab-document OCR import, DEXA import and unlimited AI meal scanning, are Phaze Pro, along with a second medication, supply tracking and Community on iPhone and Android after your first seven days in it, with monthly and yearly options. If your only requirement is a free GLP-1 tracker, Glapp and the free-to-download apps all qualify; Phaze adds a free Estimated Levels chart and free core tracking with paid AI and OCR on top.
