LeetBlock

LeetBlock is a productivity app that helps you build consistent coding habits by blocking access to selected apps until you've completed your daily LeetCode problem quota.

Features

• Daily Quota System - Set a daily goal
• App Blocking - Select which apps to block until quota is met
• Problem Lists - Create custom lists or use built-in NeetCode 250 or Blind 75 for structured practice
• LeetCode Stats - Track your total solved problems (Easy/Medium/Hard)

How It Works

1. Setup - Enter your LeetCode username
2. Set Quota - Choose how many problems you need to solve daily
3. Select Apps - Pick which apps to block (social media, games, etc.)
4. Grant Permissions - Allow usage stats and overlay permissions
5. Stay Focused - Blocked apps show a blocking screen until quota is met

Requirements

• Android 7.0 (API 24) or higher
• Flutter 3.0+

Permissions Required

• Usage Stats Access - To detect when blocked apps are opened
• Display Over Other Apps - To show the blocking overlay
• Internet - To fetch your LeetCode stats
