Free Acoustic Shot Timer

DATASHOT

DATASHOT is a free acoustic shot timer that runs in your browser. No app download, no Bluetooth device, no subscription. Point your phone at the firing line, press START, and shoot — DATASHOT detects every shot and records your split times to the millisecond.

Built for Competitive Shooting

Designed for USPSA, IPSC, IDPA, 3-Gun, and Steel Challenge. Tracks draw time, split times, and total run time in the format competitive shooters expect. Also works for dry-fire training, snap-cap practice, and laser training systems.

Key Features

  • Acoustic shot detection via microphone
  • Millisecond-precision split times
  • Real-time spectrogram visualization
  • Par time with over-par indicator
  • Random start delay (2–4 s, USPSA-legal)
  • Shot limit for fixed-count drills
  • Session history and personal stats
  • Works on iPhone, Android, and desktop

How It Works

Enable your microphone, press START, and wait for the start beep. DATASHOT uses short-term energy entropy analysis to distinguish gunshots from background noise. Each detected shot is stamped on the live spectrogram and added to the split list. Press STOP when your drill is done and review your times.

Free — No App Required

DATASHOT runs entirely in your browser using the Web Audio API. Create a free account to save your session history and track your progress over time. Use it at the range, in your garage, or at a match — wherever you shoot.
