Now with YouTube built in: search or paste a link, then loop, slow down and mark up any video. Songs, leadsheets & YouTube practice in one app.
Practice your next favorite song at half speed, bar by bar. GuitarPT turns any track into your personal practice room.
Load an MP3, M4A or video file, and GuitarPT automatically detects BPM and chords — entirely on-device, no server, no internet required. Set markers, define loop sections, drop the tempo to 50%, transpose without pitch artifacts. Once the part sits, kick the speed back up. No setup, no fuss.
Need a chord chart? Build a leadsheet in the built-in editor using a gesture-driven circle-of-fifths key picker, a smart chord palette and a clean section layout. Play it back with piano, bass and drums across 8 styles — rock, jazz swing, bossa nova, funk and more. Or snap a photo of a handwritten chart and have it digitised via OCR.
On stage? Performance mode shows large chord displays with live highlighting of the current chord.
Multiple devices? With iCloud sync your songs, markers, leadsheets and setlists are everywhere — iPhone, iPad, all in sync.

NEW
- YouTube, built in: search YouTube right inside the app or paste a link, add the video to your library, and practice it with A/B loop, pitch-preserving slow-down (slow it down without changing the pitch), markers, fullscreen, and a portrait/landscape toggle saved per video. Videos play only through the official YouTube player, embedded via YouTube's IFrame Player API -- nothing is ever downloaded, and no audio or video is copied or stored.
- One search for everything: the library search now finds songs and leadsheets together.
- Move items between projects: send any song or leadsheet to another project folder from its menu. Your manual project order now survives iCloud sync and reinstalls.
- Cleaner analysis tabs: the layer toggle hides Simplified/Theory tabs that have no data.
IMPROVED
- Free re-analysis from your cached cloud stems now keeps the Simplified and Theory layers when the analysis engine is updated -- no extra credit, no re-upload.
FIXED
- The Theory tab now respects your LLM/Theory setting when an analysis is rebuilt from cached stems.
- The recording dialog reliably closes after you name a take.
- Deleting a leadsheet removes its cloud copy immediately, so it no longer reappears on the next sync.
LANGUAGES
- Fully localized in English and German.
