Our verdict on insTuner
insTuner is a chromatic tuner for guitar, bass, piano, bowed strings, brass, woodwinds, drums, and other instruments. It detects pitch through a device microphone, line-in, or configurable input channels. The app is aimed at iOS musicians who need more than a basic note indicator, particularly players working with fine pitch control, alternate temperaments, or visual analysis. Its free plan, insTuner Free, includes instant tuning, a tone generator, built-in microphone and line-in modes, and a fixed note-wheel display.
The main distinction is the depth of its tuning and analysis tools. insTuner Pro adds instant, fine, and strobe tuning modes, including cent deviation and frequency information, plus FFT spectrum analysis and a real-time spectrogram. A historical tuning curve helps display pitch movement over time. The Pro tone generator provides four waveforms, while adjustable A4 calibration, customizable temperaments, and transposition settings support more specialized practice and performance needs. These features make Pro the more suitable choice for musicians who need detailed intonation feedback rather than quick tuning alone.
Pricing follows a freemium model: the free tier covers basic tuning and tone generation, while insTuner Pro starts at 3.99 and adds the advanced tuning and analysis tools. The app also lists Inter-App Audio, Audio Bus, and Apogee One integrations, which may suit iOS audio setups using those technologies. Choose insTuner if you want a visually detailed iOS tuner with strobe tuning, spectrogram views, and custom reference settings. Choose another option if you need Android or non-iOS support, or if the free feature set must include advanced analysis.
