PepKeep

PepKeep is a dose tracker for people on weekly or daily injections who draw from vials. It shows the exact units to draw on a U-100 syringe from your own vial and water, reminds you at every dose, counts your vials down with reorder dates, and tracks your real cost per shot. You can import entire protocols, and it manages scheduling, doses, and budget automatically. It can be run hands-free using Siri commands like "log my shot," "what's due today," and "how much is left in my vials." It does the math based on your plan and works on iPhone, Android, and desktop. A 7-day free trial is available, then $4.99/month or $39.99/year.
