Indubitubely: Ad-Free YouTube App

An iOS application that brings ad-free YouTube viewing to mobile devices through Invidious integration, featuring SponsorBlock support for a completely interruption-free viewing experience.

## The Problem: YouTube's Growing Ad Burden

As YouTube's advertising has become increasingly intrusive – with multiple pre-roll ads, mid-roll interruptions, and sponsored content segments – the viewing experience has deteriorated significantly. Mobile users are particularly affected, as traditional ad-blocking solutions don't work on iOS's native YouTube app.

## The Solution: Invidious Frontend Integration

Indubitubely leverages Invidious, the privacy-respecting alternative frontend for YouTube, to provide a clean, ad-free viewing experience while maintaining access to the full YouTube catalog.

### What is Invidious?

Invidious is an open-source alternative front-end to YouTube that:

- **Removes all advertisements** from videos
- **Protects user privacy** by not tracking viewing habits
- **Provides direct video access** without YouTube's wrapper
- **Maintains full search** and discovery functionality
- **Supports all video qualities** and formats

## Core Features

### Ad-Free Video Playback

- **Zero pre-roll ads** - Videos start immediately
- **No mid-roll interruptions** - Uninterrupted viewing experience
- **Clean interface** without promotional content
- **Background playback** support for audio-only listening

### SponsorBlock Integration

Taking ad-blocking a step further, Indubitubely integrates with SponsorBlock to automatically skip:

```swift
// SponsorBlock segment types
enum SegmentType: String, CaseIterable {
case sponsor = "sponsor"
case selfpromo = "selfpromo"
case interaction = "interaction"
case intro = "intro"
case outro = "outro"
case preview = "preview"
case music_offtopic = "music_offtopic"
case filler = "filler"
}
```

#### Sponsored Content Detection

- **Sponsored segments** - Product placements and paid promotions
- **Self-promotion** - Channel plugs and merchandise
- **Interaction reminders** - "Like and subscribe" requests
- **Intro/outro segments** - Skippable opening and closing content

### Privacy-First Design

- **No user tracking** - Your viewing habits remain private
- **No data collection** - Zero analytics or behavioral monitoring
- **Local preferences** - Settings stored only on your device
- **Proxy browsing** - YouTube never sees your direct requests

## Technical Architecture

### Invidious Instance Management

```swift
class InvidiousManager {
private var activeInstance: InvidiousInstance

func selectOptimalInstance() async {
let instances = await fetchAvailableInstances()
self.activeInstance = instances.min { $0.responseTime < $1.responseTime }
}

func fetchVideo(id: String) async throws -> VideoData {
return try await activeInstance.getVideoData(id: id)
}
}
```

The app intelligently manages multiple Invidious instances to ensure:

- **High availability** - Automatic failover between instances
- **Optimal performance** - Selection based on response times
- **Load distribution** - Spreading requests across instances

### Video Streaming Implementation

- **Direct stream access** - Bypassing YouTube's player wrapper
- **Quality selection** - User-controlled resolution preferences
- **Adaptive bitrate** - Automatic quality adjustment for network conditions
- **Download support** - Offline viewing capabilities

### SponsorBlock API Integration

```swift
struct SponsorSegment {
let startTime: Double
let endTime: Double
let category: SegmentType
let votes: Int
let locked: Bool
}

class SponsorBlockService {
func getSegments(for videoID: String) async -> [SponsorSegment] {
// Fetch community-submitted sponsor segments
}
}
```

## User Experience Design

### Familiar Interface

Despite the alternative backend, Indubitubely maintains a familiar YouTube-like interface:

- **Search functionality** matching YouTube's capabilities
- **Subscription management** for favorite channels
- **Playlist creation** and management
- **Comment viewing** (read-only for privacy)

### Customization Options

- **SponsorBlock categories** - Choose which types to skip
- **Video quality preferences** - Default resolution settings
- **Playback speed controls** - Variable speed playback
- **Dark/light mode** - Interface themes

### Performance Optimization

- **Aggressive caching** - Reduced data usage and faster loading
- **Preloading** - Next video preparation for seamless transitions
- **Background processing** - SponsorBlock data fetching during playback

## Privacy and Ethics

### Respecting Creator Revenue

While Indubitubely blocks advertisements, it encourages users to:

- **Support creators directly** through Patreon, merchandise, or donations
- **Engage with content** through comments and shares
- **Discover new creators** through the platform's recommendation system

### Data Protection

- **Zero telemetry** - No usage statistics collected
- **Local storage only** - All user data remains on device
- **No account required** - Anonymous usage by default
- **Open source transparency** - Code available for security auditing

## Technical Challenges

### Instance Reliability

Managing multiple Invidious instances requires:

- **Health monitoring** - Continuous availability checking
- **Automatic failover** - Seamless switching between instances
- **Rate limiting compliance** - Respecting instance usage policies

### iOS App Store Compliance

Navigating App Store guidelines while providing ad-blocking functionality:

- **Alternative frontend positioning** - Framing as a privacy tool
- **User education** - Clear explanation of functionality
- **Terms compliance** - Careful adherence to platform rules

### SponsorBlock Accuracy

The integration with Invidious and SponsorBlock demonstrates how community-driven solutions can provide superior user experiences while respecting both privacy and creator relationships.
