• Sharper Sleep Debugger guidance with clearer step-by-step prompts • Refreshed plan preview that highlights what's changing for your baby • Updated subscription page with real parent reviews • Bug fixes and performance improvements

Plan tab refinements - Users can now refresh their plans and insights by themselves when they think one day's log is completed - Gentle plan and Goal plans are better resolving early morning wakes issue now. - Goals mini cards are now enabled to be clickable to open up details of current situation - My Plan rows are now obviously editable. Every schedule row gets a ⋮ menu (Edit / Delete), and the swipe gesture auto-previews when you land on the tab so the affordance is visible without a tutorial. Logs comparison - The Planned panel no longer goes blank for users who haven't saved a personalized plan — it falls back to an age-appropriate default with a "tap to lock yours ›" deep-link to the Plan tab. Trends - Bedtime chart finally readable. The y-axis was anchored at midnight, which made a 7:30 PM bedtime render as a huge bar. Now the axis hugs your actual data range with time labels (e.g. "7:30p", "8:00p"), and bedtimes that cross midnight (12:30 AM) plot continuously next to 11:30 PM instead of dropping to zero. Sleep Debugger - The cause-confirmation step now uses two chat-style quick-reply chips ("Yes, generate [baby]'s plan" / "None of these fit") instead of a single button — reads more like a suggested reply, copy is personalized to your baby's name.

• A new in-app banner shows your trial status and what stays available afterward. • Sleep Plan: Current State and Target State bullets are now color-coded by severity so the most pressing issues are easy to spot. Switching between babies reliably shows the correct baby's plan. • Sleep Debugger: added a "Start fresh" option to reset a session and a top-right restart button. Loading screens now show progress messages and an elapsed-time counter. Improved accuracy on slower runs by giving the analysis enough time to complete. • Account fixes: subscription and trial status now stay isolated per account when signing in and out on the same device. • Logs screen: fixed a bug that could show duplicate log stickers after swiping between days. • Chat tab: reliably reloads when reopened.

AI Sleep Debugger The most requested feature is finally here. When your baby is struggling with night wakes, short naps, or early rising, the hardest part is not fixing the problem — it is knowing what the problem actually is. The new AI Sleep Debugger walks you through a guided diagnostic session, asks the right clinical questions about your baby's symptoms, sleep environment, routine consistency, and how your baby wakes up (happy and rested, or fussy and groggy), and then delivers a root cause analysis powered by sleep science. You get ranked possible causes, a set of targeted experiments to try, and a concrete adjusted schedule — not generic advice, but a diagnosis built around your specific baby's data and your answers. The Debugger reads your baby's logged sleep history before it even asks the first question, so it already knows what the data shows before the conversation starts. AI Chat with Three Modes The Chat tab has been completely reimagined. Instead of a single open-ended conversation, you now choose how you want help. Sleep Debugger mode launches the full diagnostic flow described above. Ask a Question mode gives you direct access to an AI sleep consultant for any question on your mind — sleep regressions, wake windows, nap transitions, feeding and sleep associations, anything. Schedule Optimizer mode analyzes your baby's current routine, detects drift from age-appropriate targets, and generates an adjusted sleep schedule with a single tap, including a preview of the plan before you activate it. All three modes are built on the same underlying model that has access to your baby's full sleep history. Sleep Issues Detection Cocoo now automatically detects potential sleep issues from your baby's logged data — things like consistent night waking patterns, chronically short naps, or bedtime drift — and surfaces them directly in the Plan tab. Each detected issue links directly into the Sleep Debugger so you can go from "here is a pattern I see" to "here is what is probably causing it" in one tap. Put to Bed Log You can now log put-to-bed events separately from sleep events. This makes it easier to track sleep onset latency — the time between when you put your baby down and when they actually fall asleep — which is one of the most clinically useful signals for diagnosing sleep associations and overtiredness. Performance and Stability Navigation is faster. The logs screen loads immediately on launch. Baby profile updates now propagate instantly across all tabs without requiring a restart. Analytics and event tracking have been overhauled so the app can better understand how parents use each feature and continue improving the parts that matter most. A number of edge cases around timezone handling, background sync, and profile switching have been fixed. Thank you for being part of Cocoo. Every piece of feedback you have sent has shaped this release. If you have a minute, leaving a review helps other sleep-deprived parents find the app.

Big update. Smarter insights. Clearer nights. If your baby is waking at night, fighting bedtime, taking short naps, or suddenly “regressing” — this update is for you. - NEW: Daily AI Baby Sleep Plan (Science and AI backed, Personalized) Cocoo is now officially an AI powered planner and optimizer for baby sleep. Our new AI analyzes your baby’s daily sleep logs and generates: • Personalized Sleep Score • Comparison to ideal sleep for your baby’s age • AAP guideline alignment • Ranked sleep issues (by severity %) • Clear sleep improvement goals No generic advice. No random blog tips. Just data-driven insights built around your baby. - Ranked Sleep Troubleshooting (Start Here) Not sure why your baby wakes up at night? Cocoo identifies what’s actually causing disruptions, such as: • Bedtime too late • Wake windows too long • Overtired cycles • Short naps • Schedule drift Each issue is ranked by impact, so you know exactly what to fix first. Fix the schedule → Improve night sleep. - Personalized Schedule Generator (No CIO Required) Every day, Cocoo builds a gentle adjustment plan you can: • Activate instantly • Save and edit • Implement step-by-step No drastic sleep training. No crying-it-out required. Just small, science-backed schedule shifts. Designed for parents who want better sleep without harsh methods. - AAP & Age-Based Sleep Guidelines Built In For your baby’s exact age band, Cocoo compares: • Total daily sleep • Night sleep range • Nap count • Wake windows • Feeding intervals Aligned with AAP gold standards and large-scale sleep data. Now you know what’s normal — and what needs adjusting. - NEW: Weekly Sleep Progress Highlights Sleep improvement should feel visible.

We’ve made Cocoo smarter, faster, and even more aligned with pediatric sleep science. Here’s what’s new: - Home Screen Widgets Logging just got easier. Add Cocoo widgets to your home screen to quickly log sleep and wake times — no digging into the app. When you’re exhausted, every tap matters. - Updated Wake Window Standards We’ve refined our wake window guidance based on the latest sleep research and AAP-aligned standards. Many babies can comfortably handle slightly longer wake windows throughout the day — and now Cocoo reflects that with smarter, age-appropriate recommendations. - Smarter Energy Tracking We’ve applied the same science-backed philosophy to our energy tracking system. Cocoo now evaluates your baby’s daily sleep pressure and awake tolerance more accurately, helping prevent overtiredness and bedtime battles. - Refined Schedule Optimizer After gathering feedback from certified pediatric sleep consultants, we’ve improved our schedule optimization logic for every age group. Adjustments are now more precise, realistic, and gentle — helping families move toward healthy sleep standards step by step. As always: No pressure. No extreme methods. Just personalized, data-driven guidance to help your baby sleep better — safely and gradually. Update now and let’s make tonight a little smoother.

This update is all about clarity — helping you understand your baby’s sleep and feeding patterns more deeply, without guessing. NEW: Baby Energy Tracking Timing is everything in baby sleep. We’ve introduced Energy Tracking to help you predict overtiredness before meltdowns begin. During awake time, your baby’s energy shifts from: Green — Well rested Yellow — Getting tired Red — Overtired zone During sleep, the battery recharges from red to yellow to green. Using pediatric sleep science, wake window research, circadian rhythm modeling, and your baby’s real sleep data, Cocoo predicts when sleep pressure is building — so you can start naps and bedtime at the right moment. Better timing leads to easier naps, fewer bedtime battles, and smoother nights. No harsh methods. Just better insight. NEW: Feeding Analytics & Trend Insights Sleep and feeding are connected. Now you can see the full picture. This version adds expanded feed tracking and analytics, including: Daily milk intake summaries Feeding frequency trends Day vs night feed comparison Intake compared to age-based norms Patterns over time Understand whether night wakings are hunger-related or schedule-related. Support better daytime intake to gently reduce night feeds. See how feeding patterns impact sleep consistency — all in one place. NEW: Minimized Breastfeeding Timer We’ve improved the breastfeeding timer experience. You can now minimize the timer while it’s running and continue browsing the rest of the app — including sleep logs, schedules, and analytics — without interrupting your session. Track feeds without being locked on one screen. Small change. Big usability improvement.

Chat is officially here Chat now lives in the navigation bar for faster, always-accessible improvements for schedules. Fixed bugs in conversation flow to make chats more reliable. Clearer schedules, better routines Schedule events are now organized into their own routines, making daily plans easier to follow and adjust. As always, we’re building with real parents in mind - thank you for growing with Cocoo.
