insTuner: Chromatic Tuner is a free, intuitive app which helps users tune their instruments quickly and accurately.

Using in depth digital signal processing solutions, insTuner achieves a high degree of sound precision and can differentiate between thousands of tune variations. For reference, the app boasts a 1/1000 semitone (or 0.1 cent) precision. The app is well crafted and intuitive for any instrument player.

Sound is visually interpreted by a fixed spinner wheel in the center of the home page. All a user needs to do is play a tune from their instrument and the tuner will show exactly what note has been played. The app can even be used as an electronic pitch pipe so that users can tune by ear and match the generated sound.

The app is well suited to tuning electric or acoustic instruments, including guitar, bass, banjo, mandolin, woodwinds, and brass instruments. The app is available for purchase through the Google Play or Apple stores for a one time fee. insTuner works with any iOS device, including iPhones, iPods, iPads, and desktops. The creators recommend the app especially for iPhone 6 and 6 plus users.

insTuner features dozens of unique options which even most users are unfamiliar with. The app supports line-in and built-in microphone modes. With needle damping, customizable transposition options, adjustable calibrations, and log-based frequency analysis, every professional musician is guaranteed to get their money's worth.

Most users appreciate the extensiveness and simplicity of the app, though some complain about persistent usability issues. Any iPod Touch Gen 3 device requires an external microphone. Devices with less storage often have a slight lag when using the app, which is frustrating when musicians need instant feedback on the note they've played.
