Phaze vs Shotsy vs Pep, which is best?

Shotsy is iPhone-first, paid, and excellent at injection rotation and dose tracking. Pep is free, simple, and covers doses and weight without much else. Phaze covers doses, side effects, weight, food (with AI scan), labs (40+ biomarkers, photo and PDF OCR), DEXA body composition, and a real watchOS app, on both iPhone and Android, in 8 languages. Side-effect logging in Phaze is structured, with severity and timeline, not a free-text note. If you only inject and you are on iPhone, Shotsy is good. If you only want doses plus weight for free, Pep is fine. If you also care about labs, body composition, watchOS, or Android, Phaze is the broader fit. Try free first, all three offer it.
