What’s new
Version 1.1.0 · Updated March 13, 2026
Protocol Archiving: Archive protocols you're no longer using instead of deleting them. Your dose history is preserved, and you can un-archive anytime. Find archived protocols in the new Active/Archived filter on the Protocols screen. Start & End Dates: Set when a protocol begins and optionally when it ends. Backdate your start to when you actually began, or set a future start. Ended protocols automatically stop appearing on your daily dashboard. Smarter Form Validation: The Add Protocol form now shows clear, inline error messages when something needs fixing — like an invalid dose or missing fields. Errors clear automatically as you correct them. Calculator Integration: When adding a peptide protocol, a quick link to the Dosing Calculator appears right in the form. Both the Dosing and Reconstitution calculators now have a "Create Protocol" button that pre-fills a new protocol with your calculated values. Cycle Sync: If you're already mid-cycle when adding a protocol, you can now set a separate Cycle Start Date so the app knows exactly where you are in your on/off cycle — no need to adjust your protocol start date.
