WaveForge
Visualize sound as a living waveform — tune an oscilloscope, build a speaker from scratch, engineer concert hall acoustics, decode whale songs, and master the physics of vibration that underlies all music and communication.
Meet your mentor
Every Spark & Anvil app has a friendly mentor character that demonstrates, praises, and patiently scaffolds learning. On-device AI personalizes the mentor's responses to your kid's progress — never connecting to a server, never collecting data.
#29B6F6 WaveForge is an acoustics and sound physics laboratory where you can see sound! Use the built-in oscilloscope to visualize your voice as a living waveform, tune vibrating strings to find resonance, design the acoustics of a concert hall, and decode whale songs using spectrograms.

What's inside
Oscilloscope Lab
Tap the microphone button and make a sound. Your voice appears as a live waveform on the oscilloscope screen. Adjust the frequency and amplitude sliders to see
Resonance & Standing Waves
Experiment with a virtual vibrating string. Adjust the tension, length, and density to find the fundamental frequency and its harmonics. Watch nodes and antinod
Doppler Effect
Watch what happens to sound waves when a source is moving. See the compression (higher pitch) as the source approaches and the expansion (lower pitch) as it mov
Concert Hall Designer
Design the perfect concert hall by choosing wall materials (wood, carpet, foam, glass) and placing speakers and listeners. Watch sound rays bounce off walls and
Mentored by Sonic — on-device AI, no data leaves the device.
How WaveForge handles your kid's data
- ✅ All progress, settings, and AI-generated content stays on the device
- ✅ No analytics, no tracking, no third-party SDKs
- ✅ No ads, no in-app purchases — you pay once
- ✅ COPPA compliant under the 2026 FTC amendments
- ✅ Parental controls + session limits + content filters built in
WaveForge runs on ForgeKit — the open-source Swift Package Manager framework that powers every Spark & Anvil app. ForgeKit ensures consistent accessibility, COPPA compliance, and design language across the portfolio, so your kid's progress and preferences feel coherent across every app they touch.
