Descriptions
Two sentences
TuneTheory is a precision tuner and a live metronome for iPhone and iPad. It shows pitch to a fraction of a cent, its clock never drifts, and one purchase unlocks everything.
One paragraph
TuneTheory hears your instrument every ten milliseconds and shows pitch to a fraction of a cent. The moment a note lands, the needle turns teal and the live waveform beneath it stands still. The instrument tuner covers 45 instruments and 228 tunings, with automatic string detection, a retune guide that shows which way each string goes when you change tunings, and a "What am I tuned to?" mode that names the tuning you're already in. The metronome places every click at an exact audio sample so it never drifts, and comes with grooves from Backbeat to Bossa Nova, living grooves that change measure by measure, and eight kits from clean clicks to felt kicks and kalimba. There is no subscription, no account, no tracking, and audio never leaves the phone. TuneTheory Pro is one purchase, forever.
Mark and wordmark
The mark is a gauge, a needle at rest, and the locked waveform. Please use these files as they are: no recolouring, no rotation, no drop shadow, no circle around the mark. The needle is teal only in the locked pose.
