DOPE — Digital Ballistics Notebook for Long Range Shooting
Digital Ballistics Notebook
Stop scribbling DOPE cards on paper. Capture conditions, distances, and adjustments automatically — then filter by any variable when you need them.
What is DOPE?
DOPE (Data On Previous Engagement) is your digital ballistics notebook. It captures everything that affects a bullet's flight — distance, windage, elevation, wind, temperature, humidity, barometric pressure, slope angle, and GPS position. Weather data is pulled automatically from your location. Every entry becomes a permanent, searchable record. When you return to similar conditions, your historical data tells you exactly where to start.

Common questions
When you create a new DOPE entry, tap the weather button and the app uses your GPS location to pull current conditions from OpenWeatherMap — temperature, humidity, wind speed and direction, and barometric pressure are filled in automatically. You can override any value manually if needed.
Yes. DOPE Pro includes advanced filtering with range sliders for distance, wind speed, slope angle, temperature, humidity, and barometric pressure. This lets you find past entries recorded in conditions similar to what you’re facing today, so you know exactly where to start dialling.
Core logging and data review work without an internet connection. You can record entries, browse your history, and use the compass — your data syncs automatically when you reconnect. Weather auto-fetch requires connectivity to reach the weather service.
