Marching band and drum corps drill at your fingertips. See how every count and every set fits into your marching show. Follow shows created on DrillbookNext.com or Drillbook Next: Directors. Drillbook Next Reader does not create shows, only follows them "Game Changer - This app is one of the most amazing tools I have used in my years of teaching marching band. So much you can do with it, no more carrying around paper charts trying to explain what a move should look like, students can watch, step-by-step, and see their coordinates the entire way. A total game changer for my band!" - SHS Drumline "Simply the best drillbook app on the App Store - As a band director, I've fallen victim to carrying around the "large binder of charts" that the profession demands. Not any more!! Upon seeing what this app can offer, it's well worth the price, both for students and directors. Seeing every dot on the field in motion and, at any time, having the ability to click on a member and see their dot book coordinate is a massive timesaver and makes rehearsals infinitely more efficient." - NBRFWooo! "Wonderful tool for drill - Beautiful, well polished, feature rich, prefect for quickly knowing what the drill should look like and the exact coordinates for any student." - Wooky "This is the best app for reading drill - I seriously can't say enough about how well this app works. Uploading a show is simple, it updates easily, it's excellent and the developer is very responsive to issues." - Roskoski Marchers Follow your dot as your marching show develops.
