Fixed: the Schedule tab's Your Stats list could get stuck partway down and not scroll to the rest of your peptides. New: Sign in with Apple, and a way to resend your confirmation email if it never arrived. New: an estimated blood level chart for every peptide, right on your Schedule tab — shows your current, peak, and trough levels based on your logged doses and each peptide's half-life. Vials are now fully manageable, not just visible. The Calculator's IU option is now split into Low IU and High IU for the right step size whether you're dosing HGH-scale or HCG-scale.
