What's New in Phase

1.2

August 21, 2026

Hey there, night owl! This update is all about what your better sleep buys you. The new Rhythm tab turns last night's sleep into a personal energy curve for the day, so you can see when you'll be sharpest, when the afternoon dip will hit, and when it's time to wind down. Take the chronotype quiz and the whole curve tunes itself to your body clock. And because coffee and workouts change everything, you can log them in one tap and watch the curve react. What's new and improved: • A new Rhythm tab: your energy mapped hour by hour, drawn from last night's sleep in Apple Health, or from your Phase schedule if Health isn't connected • Your best windows pinned right on the curve: deep work, creativity, exercise, caffeine cutoff, and wind-down, each at the time your body is actually ready for it • A dotted "typical you" baseline behind today's curve, so you can see at a glance whether today is a good day or a rough one • A chronotype quiz: find out if you're an early bird, a night owl, or somewhere in between, and Rhythm adapts the curve to match • Quick logging for coffee, workouts, and meals in one tap, with workouts and caffeine pulled from Apple Health automatically when they're there • Energy notifications you control: a quiet heads-up when your peak starts, when the dip arrives, and when to start winding down, each one optional • An Insights view that learns your patterns: your typical peak, your usual dip, and how your rhythm shifts as your sleep improves • A "Rate your Rhythm" row, so you can tell Phase how the day actually felt and help the curve get smarter • An explainer that walks through the sleep science behind the curve, with no jargon • The chart lives over a sky that follows your real day, from sunrise colors to a starfield at night • Full VoiceOver, Dynamic Type, and Reduce Motion support across everything new • Various bug fixes and stability improvements throughout the app Enjoying Phase? A quick review on the App Store means the world to us. It helps other people discover the app and keeps us motivated to keep building. Got feedback or hit a snag?
