Hi, Piano Pilot requires precise real-time note detection, MIDI integration, and accurate scoring — all within a strict 14-day deadline. This is execution-focused work, not experimentation. I’ve built audio-enabled apps with real-time input processing and MIDI support, optimizing latency by up to 40% through efficient buffering and stream handling. With 5+ years in Flutter and Kotlin, I specialize in low-latency audio processing, FFT-based pitch detection, clean architecture (MVVM/Bloc), and structured Git workflows. Plan: • Flutter cross-platform build • Platform channels for MIDI • Mic-based pitch detection (real-time FFT) • Note matching + scoring engine • Progress tracking (local DB) • Clean dark UI • Daily updates + staged test builds Timeline: 14 days confirmed. Are you targeting polyphonic acoustic detection, or is monophonic sufficient for this release?

Hi, As per my understanding: You need a fully functional Piano Pilot app delivered in 14 days, not an MVP. It must include a structured song library with sort/filter logic, MIDI keyboard integration, mic-based acoustic piano detection, real-time note matching with scoring, progress tracking, and a clean modern dark UI. The focus is accurate audio processing, stable real-time performance, and production-ready architecture. Implementation approach: I would use Flutter for cross-platform speed or Kotlin if Android-only performance is priority. For MIDI, I’ll integrate native MIDI APIs; for acoustic detection, I’ll implement FFT-based pitch detection with optimized frame processing to ensure low latency. Real-time note matching will compare detected frequencies against MIDI reference maps with tolerance thresholds. State management will follow clean architecture (MVVM/Clean layers), with a modular scoring engine and local database for progress tracking. UI will follow a consistent dark theme using reusable components. Git-based workflow with daily builds and structured milestones across 14 days ensures full feature delivery. A few quick questions: Is this Android-only or cross-platform? Do you have predefined sheet/MIDI files? Should scoring be gamified (levels/badges)? Any backend sync required or fully offline?

Hi, I have carefully reviewed your Piano Learning App development project for completing the full Piano Pilot application within a strict 14-day timeline. You require a complete build including song library with advanced sorting and filtering, MIDI keyboard support, acoustic piano detection via microphone, real-time note matching and scoring, progress tracking, and a modern dark-themed UI. I will implement the app using Flutter for fast cross-platform delivery, integrating MIDI support (flutter_midi_command), real-time audio processing with pitch detection (FFT-based analysis), and a structured clean architecture with proper state management and Git workflow. The scoring engine will map detected frequencies to expected MIDI notes with millisecond-level tolerance for accurate feedback. Implementation plan: * Days 1–3: Architecture setup, UI foundation, database schema * Days 4–6: Song library, sorting/filtering, progress tracking * Days 7–10: MIDI integration + real-time note detection engine * Days 11–12: Scoring system + acoustic detection tuning * Days 13–14: Testing, performance optimization, release build Fixed price: $600 I can start immediately and commit to daily progress updates to ensure on-time delivery.
