What's New in Latebird 1.2 Sleep Debt Tracker — Latebird now calculates your weekly sleep opportunity (the window between your configured bedtime and wake time) and compares it to a sleep need you set (default 8 hours, slider from 6–10). A debt card shows whether you are in the red or surplus this week and offers a plain-English recovery suggestion. A 14-night bar chart with a dashed target line makes the pattern visible at a glance. Morning Energy Check-In — After a respected night, a gentle sunrise banner appears on the home screen so you can tap one of five emoji to rate how you feel. Over time, Trends shows your average morning energy after respected nights vs. broken nights — so you can actually see the payoff of going to bed on time. Bedtime Consistency Score — A new Trends card grades your timing consistency A through F based on how tightly your actual session start clusters around your configured bedtime (standard deviation in minutes). Sleep science shows consistent timing anchors your body clock as powerfully as duration; the score shows you where you stand and why it matters.
