About this app

NotePak is a powerful, distraction-free PDF music score viewer built for musicians who practice and perform with sheet music on Android.

Whether you are a guitarist learning a new song, a drummer working through a chart, or a conductor studying a score, NotePak keeps your sheet music and your reference audio in one place so you can focus entirely on the music.

PDF SCORE VIEWER
Load any PDF sheet music file directly from your device. NotePak renders your scores with pinch-sharp clarity, and lets you jump instantly to any page with a single tap using the page navigation bar at the bottom of the screen. No scrolling, no hunting — just tap the page number and you are there.

FULLSCREEN MODE
Enter a fullscreen canvas with one tap, putting your score front and center with zero distractions. Audio controls and YouTube playback stay accessible as a floating overlay so you never have to leave your score view.

LOAD YOUR OWN AUDIO
Load an MP3 file from your device and play it alongside your score. Control playback speed at 60%, 75%, 90%, or 100% so you can slow down difficult passages and build up to tempo gradually. The audio player stays embedded in the view right next to your score.

YOUTUBE INTEGRATION
Paste any YouTube URL or video ID directly into NotePak and play the video as your audio reference. Watch a professional performance, follow along with a playthrough, or use a backing track — all without leaving the app. In fullscreen mode, the YouTube player appears as a floating panel so your score stays visible.

PAGE TIMING AUTOMATION
NotePak includes a unique timing system that automatically turns pages at exactly the right moment during playback. Simply enter timestamps and page numbers in the timing panel (for example: 0:05 = 2, 0:30 = 3) and NotePak will navigate to each page at the right time as your audio plays. This is perfect for performing along with a recording when you need hands-free page turns.

REC ENABLE MODE
Activate Rec Enable to control page navigation manually with dedicated forward and back buttons, even in fullscreen. This is ideal for live situations where you want reliable, tap-anywhere page control without accidentally triggering other controls.

NOTEPAK BUNDLES
Save your entire setup — your PDF, your audio file, your timing notes — as a single .ntpk bundle file. Reload it any time with a single tap and pick up exactly where you left off. Share your bundles with bandmates or students so they can open the same score and audio setup instantly.

ALWAYS OFFLINE, ALWAYS PRIVATE
NotePak works entirely offline. Your files never leave your device. There are no accounts, no subscriptions, no ads, and no data collection. Your music is yours.
