Digital Match Book
Read full descriptionHide full description
Digital Match Book is a local-first field companion for precision rifle competitors. FIND A MATCH Browse upcoming public matches, add a match shell to your library, and open the event's public Impact Scoring registration page. DMB does not collect Impact credentials. PREP AND WORK THE MATCH Move through General Match Info, checklists, stages, and Final Wrap Up. Keep target tables, stage descriptions, current zero data, equipment, and notes together. WIND AND DIRECTION Capture whole-MPH wind readings from a connected Kestrel, record target direction of fire, and review W/DOF in degrees or clock format without overwriting the competitor-owned Actual field. STAGE LOG AND RIFLE DATA Record personal hits, misses, no-shots, PEWS, impacts, and notes. Maintain rifle profiles, barrels, loads, zero cards, ladders, and bullet-count logs. DMB LAB Watch live Kestrel readings, record sessions, and analyze timestamped wind speed and direction. A simulated Kestrel is available from the Live tab for review without hardware. IMPORT AND SHARE Import or share local match packages. Optional COF document, photo, or text processing requires your own OpenAI API key and explicit approval before each upload. No Digital Match Book account is required. Working data stays on the device unless you deliberately export, share, register externally, or approve optional COF processing.

Verdict
The clearest difference is device support: AnemoTracker at 3 against Digital Match Book's 1. AnemoTracker also leads on iOS requirement (13.0 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.
