The Longshot app lets you connect to any Longshot or Targetvision camera system and see live video of your target. You can pinch to zoom and swipe to pan to get a close look, use the Blinker Shot Locator to make new shots or groups flash so they’re easier to find, tap on bullet holes to place shot markers (in multiple sizes and colors to track groups or different shooters), measure your group size and get zeroing adjustments, capture screenshots and video of your range session, and even view yourself as an overlay via your device’s rear-facing camera. The app has been completely rewritten to modern standards, giving a cleaner user interface, significantly higher frame rates, faster camera discovery, support for many cameras at once (more than before), enhanced blinker history, flexible shot marker sizing and removal (you can long-press to remove any marker in any order), and improved gallery, sessions, and support/FAQ features.
