DOPE Long Range Shooting Log

DOPE (Data On Previous Engagements) is a professional, 100% private, offline-first shooting logbook built by a shooter for shooters.

Designed to replace paper range notebooks, DOPE lets you record scope adjustments, atmospheric conditions, target positions, and plot shot groupings directly on virtual targets.

KEY FEATURES:

• 100% PRIVATE & OFFLINE-FIRST All your data – firearms inventory, ammunition records, range locations, and target photos – is saved strictly inside a local database on your device (SQLite). No account registration, no telemetry, no tracking servers, and zero ads. You maintain total control over your data with built-in JSON/ZIP backup export and import.

• RANGE CONDITIONS & GPS LOGGING

• Automatic or manual range location logging with GPS coordinates, map integration, and altitude (m a.s.l.).
• Complete weather tracking: temperature, humidity, absolute station pressure, and wind speed/direction.
• Built-in absolute pressure calculator and integration with Open-Meteo API for quick weather data fetching.

• FIREARMS & AMMUNITION INVENTORY Keep a clear chronicler's record of your rifles and loadouts. The app automatically suggests your previously used rifles, calibers, and ammo for new entries to save time at the range.

• SCOPE SETTINGS & CORRECTIONS Log your optic settings and turrets in MRAD, MOA, or clicks. Compare suggested ballistic corrections (e.g. from Lapua Ballistics) with actual scope adjustments used during firing.

• VIRTUAL TARGET PLOTTING & GROUP CALCULATION

• Plot bullet hits directly on your phone screen with simple touch controls.
• Integrated magnifier tool to precisely align hit points against a millimeter grid.
• Automatic group size and dispersion calculations in mm, MRAD, and MOA.
• Support for multiple targets per entry and adding real target photos.

• CLOUD SYNC AND BACKUP

• Sync data between all your devices.
• Store a secure back-up in cloud.
• App can work offline and sync data later.
