Project: Professional Chromatic Tuner App for Regional Mexican Music (iOS & Android) We are looking for an experienced mobile developer or development team to build a high-precision chromatic tuner app for iOS and Android, specifically focused on Regional Mexican music instruments. Our goal is to create a specialized tuner that is more accurate, more intuitive, and more visually advanced than existing solutions such as GuitarTuna, while also laying the foundation for a powerful music education platform. Core Focus: Instruments Supported The tuner will be exclusively optimized for the following instruments: * Bajo Quinto * Bajo Sexto * 12-String Guitar * 6-String Guitar * Tololoche Each instrument must include professionally accurate tunings, tailored to real-world use in Regional Mexican genres. Key Features Automatic Tuning Detection (Core Feature) * Highly accurate, real-time pitch detection * Fast and stable response, even in noisy environments * Clear visual feedback indicating whether the note is flat, sharp, or in tune * Special care for double-course instruments (12-string guitar, bajo quinto, bajo sexto) Alternative Tunings * Preconfigured tunings per instrument * Support for traditional and regional tuning variations * Ability for users to create, save, and manage custom tunings Cross-Platform Compatibility * Smooth, consistent performance on both iOS and Android * Preference for shared codebases (Flutter, React Native, Unity, etc.) or well-optimized native development Premium AI Feature: Song Analysis & Chord Extraction (Subscription-Based) A key differentiating feature of the app will be an AI-powered music analysis tool available exclusively to users with an active subscription. This feature will allow users to: * Let the app listen to a song through the microphone, or * Upload/load an audio file directly into the app Using artificial intelligence and audio analysis, the app will: * Detect the chords, notes, or tonal structures of the song * Adapt the output to the selected instrument: * Bajo Quinto * Bajo Sexto * 6-String Guitar * 12-String Guitar * Tololoche * Display the chords, positions, or tones in a clear and instrument-specific way This feature is designed for students and musicians who want to learn songs faster, practice more efficiently, and understand how real Regional Mexican music is played on their specific instrument. Only users who pay for a subscription will have access to this AI-powered song analysis feature, making it a core value driver for monetization. Key Differentiators (Beyond GuitarTuna) * A Regional Mexican–focused experience, not a generic tuner * Advanced support for traditional instruments rarely covered by mainstream apps * Modern, intuitive, and visually superior UI/UX * Designed for professional and advanced musicians, not just beginners * Built with scalability in mind for future educational and AI-driven features Future Vision: Courses & Lessons Platform The app should be architected from the beginning to support future expansion, including: * Video courses for each instrument * Structured lessons (beginner, intermediate, advanced) * Exclusive content from professional musicians and instructors * Subscription-based memberships and in-app purchases * User progress tracking and gated content Note: Not all of these features are required for the initial release, but the architecture must support future growth. Ideal Skills & Experience * Proven experience in iOS and Android mobile development * Strong background in: * Audio processing * Pitch detection algorithms * Music information retrieval and AI-based audio analysis * Experience building music or audio-related apps (highly preferred) * Strong UI/UX sensibility * Ability to design scalable and maintainable architectures When Applying, Please Include * Examples of relevant or similar apps (tuners, audio, music, education) * Proposed technology stack * Experience with audio signal processing and AI-based analysis * Any ideas or suggestions to improve the product Our mission is to build the ultimate tuner and learning platform for Regional Mexican musicians. If you’re passionate about music technology and want to create something truly unique, we’d love to hear from you.
