VialTrack

Read full description

VialTrack helps you stay clear, consistent, and organized when managing complex personal protocols. Instead of juggling notes, spreadsheets, reminders, and vial math, VialTrack gives you one private place to understand what is due, what you logged, what you have left, and how your progress is trending over time. Create custom protocols from a compound library, plan dosing and titration phases, log doses in seconds, rotate injection sites, track symptoms, and follow progress metrics that matter to you. VialTrack also helps you manage reconstituted and unmixed vial inventory so you can better understand what you have on hand and when supply may be running low. For users who want a deeper view of their routine, VialTrack can show estimated compound level trends based on the information you enter, helping you visualize schedule timing and protocol history more clearly. Your data stays private. VialTrack is local-first and does not require an account. When iCloud is available, your app data can sync and back up through your private iCloud database. Optional Apple Health syncing can import or export selected metrics with your permission, such as weight, waist circumference, and sleep. VialTrack is designed for personal organization and tracking. It is not a medical device or healthcare provider, and it does not provide medical advice, diagnosis, dosing recommendations, or treatment guidance. Always consult a qualified healthcare professional before starting, changing, or stopping any medication, supplement, protocol, or treatment.
