Gilly is so easy to use, and has a great UI. But the best part is that it’s helping me finally take my shot on time. In addition to the reminders, seeing the chart of the level of medication in my body is really motivating me to take it!
Incredible Features and Layout
Anechka3223
I chose this app on a whim to help me track my WL journey. I saw a few people recommend it on Reddit and my FB WL groups. I love the features and it’s so easy to use. I was able to add some custom meds to track some other supplements I take too!
This update follows your journey past goal weight — plus a faster layout, widgets, and support for the newest GLP-1.
MAINTENANCE MODE
Reached your goal weight? Gilly now helps you stay there. When your weight reaches your goal, a banner invites you to begin maintenance — pick a start date, set a target weight and an acceptable range, and shift your focus from losing to holding steady. Gilly tracks how long you've been in maintenance and what percentage of days you've stayed in range, with an at-a-glance "On Track" or "Watch" status. You can switch between Active Weight Loss and Maintenance anytime in Settings, and look back on your weight-loss history whenever you want a little motivation.
NEW MEDS TAB
We restructured the tab bar around a dedicated Medications tab. See your next dose at a glance, browse your full medication list in brand-colored tiles, and jump straight to what you need. (History is still here — under "Browse all entries" in Insights.)
HOME & LOCK SCREEN WIDGETS
Keep your next dose in view without opening the app, with new home screen and lock screen widgets.
SHOT PLANNING CHARTS
Plan ahead with new injection-planning charts to map your doses over time.
WEIGHT MAINTENANCE CHART
Scrub across the timeline to read any point, with axes and summary stats that stay in sync.
FOUNDAYO (ORFORGLIPRON)
Added the newest oral GLP-1 to our 30+ medication database, so you can log it alongside everything else.
WHAT'S NEW, IN-APP
A new feature-discovery system with guided coach marks walks you through everything above.
Gilly keeps all your data on your device — always private, never uploaded. Thanks for tracking with us.
