## What is Fitness Guardian?

Do you find yourself mindlessly scrolling through social media?
Are you losing hours every day on apps that give you nothing in return?
This app takes a different approach.
It blocks distracting apps until you move your body and burn calories.

Want to get fit and gain hours back every day?
Are apps stealing your time and pushing you into procrastination?
Fitness Guardian helps you earn your screen time.
You unlock app usage by burning active calories. Once you run out, it’s time to move again.

We use basic calorie data from Apple, so it doesn’t matter how you track your activity.
As long as your data is synced with Apple Health, it will work seamlessly with this app.
This is a powerful way to stay motivated, reduce doomscrolling, avoid brain rot, and eliminate procrastination.

Best way to use the app:
- Allow required system permissions (activity tracking and app blocking)
- Select apps you want to block when your time runs out
- Choose your difficulty and activate the lock
- Once your time is used up, selected apps stay locked until you burn more calories

Works with all devices that sync activity data to Apple Health
- No AI, no external data sharing – everything stays on your device
- Difficulty levels: (Easy: 10 kcal/min, Medium: 50 kcal/min, Hard: 100 kcal/min)
- Custom widget showing remaining time and lock status

Turn bad habits into motivation:
- Every calorie burned gives you more time
- Build habits naturally without forcing yourself
- Less scrolling, more real life

Who is this for:
- People who spend too much time on social media
- Anyone looking to build discipline
- Fitness beginners who need motivation
- People who want to be more productive

This is a paid app:
- Each plan includes a 3-day free trial
- Weekly plan with 3-day trial, yearly plan with 3-day trial
- A subscription is required to use the app

The app uses a recurring subscription model that you can cancel anytime.
