# Life Score™- iOS


### What is the Life Score™?

The Life Score™ is a weekly health tracker in the Lifesum app that evaluates your overall health based on **16 key nutrition and exercise metrics**. It provides:

* A comprehensive score (0–150) reflecting your lifestyle habits.
* Personalised feedback highlighting areas where you excel and suggestions for improvement.

|| In order to get access to all details about your Life Score™ you need a premium subscription.

### How is the Life Score™ calculated?

The score is based on:

1. **Nutrition**: Are you consuming adequate fruits, vegetables, unsaturated fats, and other key food and nutrients?
2. **Water Intake**: Are you staying hydrated and logging your water consumption?
3. **Exercise**: Do you have a balanced mix of activities, including strength, low-intensity, and high-intensity exercises?
---
### Tracking Methods

* **Health Test**: Complete a 41-question test to receive an initial score. You can retake the test to update your score until you regularly track your habits.
* **Daily Tracking**: Once you consistently log food, exercise, and water, your score will reflect this tracked data for more accuracy.
* **Habit Trackers**: Activating habit trackers (e.g., for water, vegetables, fruits) contributes to your score and helps you stay on top of specific goals.
---
### Weekly Score Updates

Your Life Score™ updates every Monday, summarising your progress and areas for improvement. If you retake the Health Test or log habits consistently, your new score will overwrite the previous one.
---
### What does the score mean?

The Life Score™ ranges from 0 to 150, with these categories:

* **Optimal (120–150)**: Excellent balance in nutrition, hydration, and exercise.
* **Great (90–120)**: Very good habits, with room for slight improvement.
* **Good (60–90)**: A solid foundation with areas to strengthen.
* **Imbalanced (30–60)**: Significant adjustments are needed.
* **Off Track (0–30)**: Considerable lifestyle changes are required.

The app also compares your score to the previous week and displays improvements or declines (e.g., "+6 points" or "-8 points").

### Key Features of the Life Score™

* **Highlights**: Personalised suggestions to focus on specific habits, like tracking water or increasing fruit intake.

### Common Questions

1. **Why do I have a low fish score if I’m allergic?**
If you've noted allergies to both fish and shellfish, your score won't be penalised, if you have entered your allergy/preferences in the nutritional settings. Alternatively, use the fish tracker to log Omega-3 supplements as a replacement.

2. **Why is my strength training score low when using a partner app?**
Exercises imported from some apps may not be fully compatible. Use Lifesum's exercise tracker for accurate results.

3. **Why can’t I retake the Health Test?**
Once you log enough data, your score is calculated from your tracking habits rather than the test. This provides a more accurate reflection of your lifestyle.

### Why Track Regularly?

Frequent tracking ensures a more precise and actionable Life Score™. The more data you log, the more tailored and beneficial the feedback becomes.
