Frequently asked
What's the best peptide tracker app?
It depends on what you need. DoseCraft is the most complete — protocols, evidence-tiered library, calculators, an AI coach that actually answers, and tracking — across web, iOS, and Android. Shotsy is a strong, simple GLP-1 injection tracker. PepStackr is a free web stack builder. Compare the full feature matrix above and pick what fits your goals.
Is there a free peptide tracker app?
Yes — PepStackr is free (web), and Shotsy has a free tier. DoseCraft offers free no-signup calculators plus a 14-day full-Pro trial (no card required), then $19.99/mo.
What's a good PeptIQ alternative?
DoseCraft covers what PeptIQ does and adds a three-lane evidence model, an interaction checker, PK concentration curves, a fact checker, and web + Android support (PeptIQ is iOS-only). Verify current PeptIQ features yourself — apps change.
Does any app calculate reconstitution and the syringe draw?
Yes. DoseCraft's free reconstitution calculator returns concentration and the exact insulin-syringe unit mark to draw, with a visual syringe. PeptIQ, Shotsy, and PepTracker also offer reconstitution math in varying depth.
