What's New in Peptide Tracker
1.1.0
August 3, 2026
FORMS THAT LINE UP Every field, picker and date now shares one clean left edge, and text no longer sits jammed against the edge of its box. This affects the log, calculator, vials and schedule screens. A CLEARER SCHEDULE SCREEN Adding a schedule now shows only the fields that apply to the pattern you picked, instead of every option at once. "Weekly" is now called "Specific days of the week", which is what it actually does — you choose the individual days. ALSO IN THIS RELEASE - Tidier launch screen. As always: your data stays on your device. No account, no analytics, no tracking.
