Whether you want to write better songs, improvise with confidence, read sheet music, or train your ear, Sonid provides a clear, step-by-step path to musical mastery. Unlike other apps that overwhelm you with information, Sonid focuses on single-subject learning. This structured approach ensures you master notes, intervals, and scales before moving on to complex jazz harmony and chord substitutions. WHY CHOOSE SONID?

Musical Playground: Visualize any scale, chord, or interval on a virtual fretboard, keyboard, or staff to see how the notes connect. Shared Assignments: Create a custom exercise and share it with a link or QR code. Teachers, students, and friends can take the same test—and you can follow their results. BUILD YOUR THEORETICAL KNOWLEDGE Every musician needs a strong foundation. Sonid gives you the tools to: Read Sheet Music: Learn treble and bass clef, note values, rests, meters, and rhythm so you can play from written music with confidence.

About

CodeLoom

Features
Read full description

CodeLoom is an interactive educational app that teaches the basic concepts of programming through stories. Instead of starting with code, you learn to think like a programmer by creating narratives, making decisions, and shaping narrative worlds. Here, programming means telling a story. Learn computational thinking without writing code CodeLoom gradually introduces the fundamental concepts of programming using a clear and accessible narrative metaphor. Variables represent the traits of characters. Conditionals decide what happens if something occurs. Loops reflect actions that repeat over time. Events are moments that move the story forward. Functions define the abilities or actions available. Everything is learned in a visual, creative way, with no prior knowledge required. Interactive stories that evolve with you Each story presents situations that require logic and decision making. As you progress, new challenges appear, encouraging you to think, experiment, and adjust your choices so the story can continue. There is no single correct solution. Each decision opens some paths and closes others, just like real programming. AI as a creative guide, not an automatic answer CodeLoom uses artificial intelligence to generate situations and suggest narrative challenges that help develop logical thinking. On devices compatible with Apple Intelligence, AI can also help refine and enrich the stories you create, while keeping the user as the main protagonist of the process. The AI does not solve things for you. It proposes scenarios where you apply what you have learned and continue building the story. Natural exposure to other languages Stories can be played in different languages, allowing contextual exposure to language while developing logical thinking. CodeLoom is not a traditional language learning app. Language understanding emerges naturally through reading and interacting with stories. Who is CodeLoom for People who want to understand how programming works. Students and teachers looking for a creative approach. Curious users with no previous experience. Anyone who enjoys learning through stories. You do not need to know how to program. Just curiosity and the desire to create. CodeLoom where stories become logic. Advanced AI features for improving stories require devices compatible with Apple Intelligence.
