Games
Free · Designed for iPad. Not verified for macOS.
Harmivelle is a colorful pocket puzzle lab where a few simple frequency tools lead to satisfying discoveries. Tap a tool, choose a frequency block, and shape the values until they match the target.
TEN HANDCRAFTED EXPERIMENTS
Work through 10 compact puzzles about doubling, tripling, halving, filtering, harmonic stacks, resonance windows, and wavelength. Each level introduces a clear idea and explains the relationship behind its solution.
SMALL MOVES, CLEVER SOLUTIONS
Some puzzles ask for one frequency. Others ask you to preserve several components or work around a locked block. Plan your operations, test your result, and experiment again whenever you like.
LEARN BY PLAYING
A guided first level shows you how to forge your first result. Three-stage hints offer a nudge when you need one. Open the spectrum lens to inspect your components, or switch between frequency and wavelength views.
MAKE EVERY STAR COUNT
Earn a star for completing a level, another for solving it without the spectrum lens, and a third for an optimal solution without the lens. Replay completed puzzles to improve your results.
A CALM, COLORFUL LAB
Enjoy warm colors, clear cards, responsive portrait layouts, and optional sound and haptic feedback. There are no timers, lives, ads, in-app purchases, or accounts. All 10 levels are included, and progress is saved on your device for offline play.
Harmivelle uses a simplified educational model of frequency relationships, with a fixed sound speed of 340 m/s for wavelength examples. It is a numerical puzzle game, not an acoustic wave-mixing simulator or a musical instrument.
