A clearer name, and a fresh look on the App Store. • Ligand is now "Ligand · Peptide Tracker" — the same app, named for the thing you open it to do. • New screenshots and a new preview video: the calculator with its working shown, a saved calculation reopened, your saved list, your log, a vial, and the week you planned. Nothing in the app itself changed in this release.

Save your calculations — and check every number. • Save any dose calculation and reopen it later: your inputs, the full working, and the exact-vs-rounded result, frozen. • Enter your target in mg or mcg — your choice. • Share a calculation as plain text — the whole derivation, ready to paste. • Free to try, no account. • Pro: export & back up your records (CSV + JSON), now also available as a one-time Lifetime purchase. • A new icon and a cleaner look throughout. Ligand does the math and keeps your log. It never tells you what to take.

Behind-the-scenes refinements for a smoother, more reliable experience. Thanks for using Ligand!
