Oscillations and Waves Virtual Lab. A professional physics simulator for mechanical oscillations and wave phenomena. 12 CLASSICAL EXPERIMENTS IN ONE APP Simple Harmonic Motion (spring-mass system) Simple Pendulum and Energy Analysis Damped Oscillations (underdamped, critically damped, overdamped) Forced Oscillations and Resonance Curves Transverse Waves on a String Standing Waves and Harmonic Modes Longitudinal (Sound) Waves Wave Interference and Beat Phenomena Doppler Effect Simulation Double-Slit Interference Pattern Lissajous Figures and Phase Comparison Coupled Oscillators and Normal Modes INTERACTIVE AND REAL TIME Every parameter is fully tunable: mass, spring constant, length, damping coefficient, driving frequency, wave speed, tension, slit separation, and more. Adjust any value at any time and watch motion, waveforms, and energy change live on canvas. ACCURATE PHYSICS ENGINE All simulations are based on real-time numerical solving of motion equations (Newton second law, wave equation, SHM differential equations). Energy bar charts, phase-space portraits, resonance curves, and Lissajous figures are all actual calculation results, not pre-rendered animations. AI POWERED LAB REPORT GENERATOR After running an experiment, one tap generates a full physics lab report. Report includes: experiment objective, setup description, data tables, graph analysis, error discussion, and conclusion. All powered by AI. Reports can be exported as PDF for printing or sharing.

Verdict

The call

The clearest difference is price: Flex Metronome at Free against Oscillations & Waves Lab's $4.99. Flex Metronome also leads on iOS requirement (14.0 vs 17.6). Oscillations & Waves Lab's advantage is update cadence (every 3 weeks vs every 3 months). On ads, in-app purchases and device support there is nothing between them.
