- Keep your go-to calculators in the Favorites tab and open them in one tap
Electrical calculators
Ohm's law, power, speaker impedance and dB-to-power-ratio conversion in one place.
Distance, time and phase delay
Convert between distance, time and phase, and see the phase difference between the direct and delayed signal as a graph.
Tap tempo and note length
Tap to measure BPM and see note lengths in milliseconds for that tempo.
