BTCBitByBit App vs Polym

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.

Science-Backed Audio Courses

Polym delivers medium-form audio content specifically curated on foundational subjects that are universally relevant. We go beyond surface-level explanations, focusing on the core concepts and abstract principles of fields like logic, statistics, and computer science. Our content is meticulously scripted and produced to be effective in an audio-only format, ensuring complex ideas are communicated clearly and memorably without relying on visual aids.

Active Learning with Audio Flashcards

Passive listening is not enough for true mastery. Polym integrates retrieval practice directly into the experience through interactive audio flashcards. These prompts challenge you to actively recall key definitions, concepts, and relationships from your courses, strengthening neural pathways and dramatically improving your ability to remember and apply the information when you need it most.

Intelligent Spaced Repetition System

Our app doesn't let you forget. Polym's built-in algorithm uses spaced repetition, prompting you to review material at strategically increasing intervals. This method is scientifically proven to combat the forgetting curve, ensuring that what you learn today is consolidated into your long-term memory for months and years to come, all managed automatically by the app.

Interleaved Practice Sessions

To build deeper understanding and flexible knowledge, Polym employs interleaving. Instead of drilling one topic in isolation, your active learning sessions will intelligently mix related concepts from different courses. This technique enhances your ability to discriminate between ideas and apply them in varied contexts, forging stronger connections across your entire knowledge base.

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.

The Career Accelerator

A marketing professional needs to deeply understand data statistics to present results convincingly. A product manager wants to grasp core AI principles. Polym provides the efficient, on-the-go learning path to master these foundational skills, boosting professional credibility and opening doors to new opportunities without requiring textbook study.

The Exam Preparation Aid

A university student studying for comprehensive exams in economics or computer science uses Polym to reinforce lecture material. The audio courses and flashcards offer a perfect way to review key terms and concepts during walks or gym sessions, turning downtime into productive, memory-enhancing study sessions that complement traditional study methods.

The Lifelong Polymath

A curious individual with a passion for continuous learning wants to build a robust understanding of philosophy, history, and logic. Polym offers a structured yet flexible curriculum across disciplines, feeding their intellectual curiosity and helping them connect ideas across fields, all through an engaging audio format that fits into a busy lifestyle.

The Commute Transformer

Turn wasted drive time or daily transit into a productive learning journey. Instead of just listening to music or news, users can immerse themselves in a course on cognitive biases or probability, actively engaging with the content via flashcards. This transforms the daily commute into a consistent habit of knowledge acquisition and mental sharpening.

Is BTCBitByBit safe for my family to use?

Absolutely. Security is the top priority. The app employs bank-level, end-to-end encryption, two-factor authentication, and biometric login (Face ID/Fingerprint). Most importantly, it is a non-custodial wallet, meaning you—and only you—hold the private keys to your Bitcoin. We never have access to your funds.

What age is the app appropriate for?

The app is designed for the whole family! The curated content includes courses for complete beginners, making it suitable for older children, teenagers, and adults. 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.

What research supports Polym's learning strategies?

Polym's methodology is built on decades of cognitive science research. Techniques like retrieval practice (actively recalling information), spaced repetition (reviewing at optimal intervals), and interleaving (mixing topics) are consistently shown to be far superior to passive review for long-term retention. You can explore a foundational overview of this research via the National Institutes of Health here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9781761/.

What subjects does Polym cover?

We focus on foundational knowledge that applies broadly. Our current and growing library includes courses on Logic, Logical Fallacies, Cognitive Biases, Statistics, Probability, Scientific Research Methods, Algorithms, Economics, Philosophy, and History. We select subjects that provide critical thinking tools and frameworks useful in both professional and everyday contexts.

Who is the Polym app designed for?

Polym is for anyone who values lifelong learning and wants their knowledge to last. It's ideal for professionals looking to upskill, students supplementing their studies, and intellectually curious individuals who want to become modern-day polymaths. If you've ever learned something only to forget it later, Polym is built for you.

How does Polym handle technical/mathematical content in audio?

We address this challenge directly by carefully selecting the subset of technical and mathematical concepts that are suitable for audio explanation. We focus on conveying the underlying principles, abstract relationships, and real-world applications, rather than complex notation. This approach actually strengthens conceptual understanding and the ability to apply the knowledge flexibly.
