• Audio Editing - Trim recordings with draggable handles, preview trimmed audio, save copies
• Transcription - On-device speech-to-text transcription
• Audio Enhancement - Improve recording quality with one tap
• Organization - Create folders, favorite recordings, search and sort by date/name/duration/size
• Batch Operations - Multi-select recordings to share or delete in bulk
• Location Naming - Automatically name recordings based on your current location
• Premium Subscriptions - Weekly, monthly, yearly, and lifetime tiers
• Accessibility - Full VoiceOver/TalkBack support

Requirements: iOS 17.0+, Xcode 15.0+, Swift 5.0+

open ios/EchoNote.xcodeproj
# Select target device/simulator, then Cmd+R

No third-party dependencies. Uses only Apple frameworks.

Requirements: Android 8.0+ (API 26), Android Studio, Kotlin 2.0+

cd android
./gradlew assembleDebug

Both platforms follow the MVVM (Model-View-ViewModel) pattern:

• Models - Data layer (SwiftData on iOS, Room on Android)
• ViewModels - Reactive state management (@Observable on iOS, StateFlow on Android)
• Views - Declarative UI components (SwiftUI / Jetpack Compose)
• Services - Platform API wrappers (AVFoundation / MediaRecorder, etc.)
