Finding your way around. Haven has twelve areas: Today, Run, Coach, Track, Plan, Records, Experiments, Doctor, People I Care For, Research, Tasks, and Settings. On a phone the bar at the bottom shows Today, Run, Coach and Track, and "All areas" opens the rest. On a wider screen all twelve sit in the bar.
What Today shows. Today is Haven's home screen. At the top are three buttons: Start Run, Log Food and Ask Coach. Start Run begins a run in one tap. Below them is the Run card, then the one next best action for today — press "Why?" to see the reason and the data it was based on. Then your maintenance dashboard: your 7-day and 14-day average weight, the trend, your target range, your latest weigh-in, today's calorie, protein and fiber targets and saturated-fat ceiling, and the status of your workouts, medications, blood pressure, labs, alcohol and any experiment. After a drink, a short note reads the next day in context. Today also shows your next task and, when it matters, a reminder about a doctor question or a lab.
What the target range and the trend words mean. Haven reads your weight as a trend, not a single day, because one day's number moves for many reasons — water, salt, a late meal, a hard workout, a drink. "Drifting up" or "Drifting down" describes the recent trend; "Above range" or "Below range" compares it with your range. A one-day change never moves a target. Your daily targets start as provisional estimates and settle as Haven learns your trend. You can set your own protein floor, fiber floor, saturated-fat ceiling and calorie starting point in Settings › Your maintenance numbers; a value you have not set is marked as Haven's default.
Logging on Track. Track is for what happened today. It has tabs for Food, Weight, Workout, Blood pressure, Medication and Lab. Food opens on the camera: take a photo of your meal and Haven estimates it. Or tap "Same as yesterday", your usual meal, a saved meal, or scan a barcode — or say or type what you ate. Each tab has one button to save, and the date and time default to now.
Step-by-step instructions for each kind of entry are in "How to log a reading".
Planning ahead. Plan is for what you decide in advance: this week's meals and Sunday prep, a training week, and planning around a drink. Alcohol planning lets you set how many drinks you intend to have, plan dinner and hydration, and see what tomorrow may look like. It is private and without judgment, and Haven never says any amount of alcohol is safe.
Where things appear. What you log shows on Today and in Records. Runs recorded with the Haven phone companion arrive from Health Connect on your phone; other readings you log yourself.
