The INTUNATOR is ingenious and simple: You just put on your headphones (or bluetooth box), play your instrument, listen to the correct pitch in your headphones and match it on your instrument. It’s that simple to find the correct intonation and be in tune! The INTUNATOR is a practice aid to help you with correct intonation. It is designed to work with all wind and string instruments and (NEW) with human voice. The app recognizes the pitch that is played and corrects it to the ideal pitch. It simultaneously plays the correct sound on your headphones. When you match the same tone while playing, you intuitively learn how to produce perfect intonation on your instrument. Our transposing tuner is for free. With an In-App-Purchase you can upgrade to TUNER PRO or to INTONATIONTRAINER. You can check out both of them free for 2 or 4 weeks without obligation. If you don't like it, just cancel your subscription in good time. Try it out! Terms of service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
