What's New in Gretl
1.0.0
September 21, 2026
Barcode scanning. Point your camera at a package and Gretl reads the product's nutrition straight off it, the one place in the app where the numbers are read rather than estimated. The barcode is decoded on your phone; only the digits are ever sent, never a picture. Scanning is part of Gretl Pro, and photographing the nutrition label still works on any plan. Plus a long list of fixes you asked for: reminders that quietly stopped arriving, a weekly check-in that never showed up, labels overlapping on Trends, and re-logged favorites that left their fiber and cholesterol behind. Keep the reports coming, they work.
