BTCBitByBit App vs Interactive Circle of Fifths

Self-Custody Lightning Wallet

Your family's Bitcoin is truly yours. The app features a built-in, non-custodial Lightning wallet powered by the Breez SDK, ensuring you control your private keys. Enjoy instant, feeless Bitcoin transactions for sending and receiving, making real-world use of Bitcoin fast and practical. This foundational feature teaches the critical principle of self-sovereignty from day one.

Learn & Earn Rewards

Education is directly incentivized with real Bitcoin rewards. Family members complete interactive quizzes and expert-designed courses tailored to different age and experience levels. For every lesson mastered, you earn satoshis, transforming learning from a chore into an exciting game where knowledge literally pays. This gamified approach makes complex concepts stick.

Family Corner & Chore Management

This powerful parental dashboard puts you in control of your family's Bitcoin journey. You can create individual child wallets with oversight, assign chores and tasks, and reward completion with sats. It seamlessly blends financial education with real-life responsibility, teaching kids the value of work and sound money through direct, hands-on experience.

Monthly Sats-Back Subscription

Upgrading your plan isn't just an expense—it's an investment that pays you back. Premium subscribers earn back half of their monthly subscription fee in satoshis. This unique model aligns the app's success with your family's wealth-building goals, effectively reducing the cost of premium features as you continue your educational journey.

Dynamic Circle & Key Exploration

Click on any key around the circle to instantly reconfigure the entire tool. Watch as the inner rings, chord panels, and scale information update in real-time to reflect your chosen key. This allows for seamless exploration of all twelve major and minor keys, visually demonstrating their relationships and shared chords. It's the fastest way to understand modulation and the intrinsic structure of the Circle of Fifths itself, making key signatures and their connections crystal clear.

Multi-Instrument Visualizers (Piano & Guitar)

Go beyond theory and see exactly how to play. Integrated piano and guitar fingerboard visualizers light up to show you the precise notes and recommended fingerings for any selected chord or scale. This feature directly translates harmonic knowledge into muscle memory, helping beginners learn shapes and aiding advanced players in finding new voicings and positions across the neck or keyboard instantly.

Comprehensive Scale & Chord Library

Dive deep into harmonic building blocks with dedicated selectors for scales and chords. Instantly display and hear major, minor, and diminished chords. Explore essential scales like the Pentatonic, Blues, Diatonic, and Diminished scales directly from the inner ring. This library puts a universe of melodic and harmonic colors at your fingertips, encouraging experimentation and a deeper understanding of scale-chord relationships.

Harmonized Scale & Chord Sequencer Panel

This powerful panel displays all the diatonic chords (like C, Dm, Em, F, G, Am, B°) for your selected key, labeled with both their musical names and Roman numeral functions (I, ii, iii, etc.). Understand chord function, see what each chord "resolves to," and use this knowledge to build rock-solid or creatively unexpected progressions. It's the ultimate cheat sheet for songwriting and analyzing the music you love.

Introducing Kids to Money & Earning

Parents can use the chore management system to assign age-appropriate tasks. When a child completes a chore like cleaning their room or taking out the trash, they are rewarded with satoshis directly into their own wallet. This teaches the core concepts of earning, saving, and the value of work using sound money from a young age.

Structured Family Bitcoin Learning Sessions

Families can set aside weekly "Bitcoin time" to tackle courses together in the Learn & Earn module. Parents and children can progress through beginner to advanced content, quiz each other, and collectively watch their family sats stack grow as they learn, making financial education a collaborative and rewarding family activity.

Sending Instant, Feeless Allowances

Forget cash or bank transfers. Parents can use the instant Lightning wallet to send weekly allowances or special reward sats directly to their child's wallet within the app. This gives kids immediate, practical experience with digital transactions and introduces them to the future of fast, borderless payments.

Securing Family Savings in Bitcoin

The family can use the self-custody wallet as a collaborative savings tool. By regularly converting a portion of savings into Bitcoin and storing it securely in their own wallet, families learn about long-term holding ("HODLing") and can watch their generational wealth grow together, all while maintaining full control of their assets.

Songwriting & Chord Progression Design

Break through creative blocks by using the Harmonized Scale panel and Chord Sequencer. Experiment with different diatonic chords (I, IV, V, vi) in any key, hear how they sound together, and discover smooth, functional progressions. The "Resolves To" function provides expert guidance on natural harmonic movement, helping you craft verses, choruses, and bridges that are both emotionally compelling and theoretically sound.

Instrument Learning & Practice

Ideal for students on piano or guitar. Use the visualizers to learn chord shapes and scale patterns in any key. A guitarist can practice the blues scale in A, while a pianist drills the diatonic chords in F# minor. It turns practice sessions into exploratory missions, reinforcing the connection between the notes on the screen, the sounds you hear, and the physical layout of your instrument.

Music Theory Education & Visualization

Teachers and self-learners can use the tool to visually demonstrate abstract concepts. Show how the circle is built, how relative minors work, or what makes a dominant seventh chord want to resolve. Watching the entire interface change with a single click makes theory tangible, accelerating comprehension far beyond textbook diagrams and rote memorization.

Improvisation & Solo Development

Select a backing chord from the sequencer and then explore compatible scales from the inner ring, like the Pentatonic or Blues scale. The visualizer shows you the "safe" notes to play over that chord across the entire fretboard or keyboard. This builds confidence and vocabulary for soloing, helping musicians move from playing memorized licks to creating meaningful, in-key melodic phrases on the fly.

Absolutely. Security is the top priority. The app employs bank-level, end-to-end encryption, two-factor authentication, and biometric login (Face ID/Fingerprint).

The parental controls in the Family Corner allow you to manage and tailor the experience for younger children, making it a flexible tool for all ages.

How does the "Sats-Back" reward work?

When you subscribe to a Premium or Standard plan, you automatically earn back 50% of your monthly subscription fee in satoshis. These sats are credited to your wallet within the app, effectively reducing your net cost and rewarding you for committing to your family's Bitcoin education journey.

Can I use the app without spending money?

Yes! The Free plan offers a robust starting point with a self-custody Lightning wallet and beginner Bitcoin courses. You can fully explore the basics of Bitcoin and wallet management without any cost. You only upgrade to a paid plan to unlock advanced features like Learn & Earn rewards and the full Family Corner.

Do I need to know music theory to use this tool?

Not at all! The Interactive Circle of Fifths is designed to teach you theory through interaction. You can start by simply clicking on keys and chords to hear them and see the fingerings. The visual relationships on the circle and panels will intuitively guide your understanding, making it perfect for absolute beginners while still being a powerful reference for advanced users.

Which instruments does this support?

The tool provides dedicated visualizers for both piano (keyboard) and guitar (fretboard). When you select a chord or scale, the corresponding notes are highlighted on both instrument diagrams, giving you the exact fingering. The core theory concepts apply universally to all instruments, from bass to vocals.

Can I use this to help me write a song in a specific key?

Absolutely. First, select your desired key on the outer circle. Then, use the Harmonized Scale panel to see all the chords naturally available in that key. The Chord Sequencer lets you audition different progressions (like I-V-vi-IV) and hear how they sound. It's the perfect tool for writing a pop song in C Major or a blues tune in E.

What is the "Resolves To" function?

This feature, found in the chord panel, teaches you about harmonic tension and release—a core concept in music. It shows you which chord(s) a selected chord naturally wants to progress to, based on traditional music theory. For example, the V chord (dominant) strongly "resolves to" the I chord (tonic). Using this guide helps you create chord progressions that sound satisfying and complete.
