What's New in Glug
1.1.0
September 10, 2026
Your fish is alive now. Log a drink and it darts across the tank, turns to face where it's going, then settles and breathes while it waits. It grows as your daily progress climbs. Five new ways it shows up: tap the glass and it reacts, it greets you when you open the app, it sleeps at night, it blows mouth bubbles, and it lets you know when it's thirsty. Two new health states: thriving when you're ahead of your goal, worried when you're slipping. Six in total, and the tank, the widget and the stats calendar now all read from one table, so they can't disagree. The tank is full-bleed: water edge to edge instead of a box in the middle. Fixed: the oz counter could overlap itself on the home screen.
