Every shot.
Accounted for.
A calibrated G7 ballistic solver paired with a rifle-data system that turns every range day into intelligence for the next.
- Per-Rifle Real velocity, BC, and zero per load — not generic curves
- Web · Android All data · multiple devices
- Unlimited No caps on firearms, loads, or sessions
Three systems. One workflow.
Logbook
Live capture every shot — wind, dial, hold, group, atmospherics. Sessions feed the lifetime stats automatically.

Each firearm carries its barrels, confirmed loads, zeros, and history. One source of truth, every screen, every device.

G7-canonical solve against your real rifle and your real load. Range, wind, Coriolis, spin drift — through transonic into subsonic.
See it solveCapture the day. Not the memory of it.
Log shots while you're still on the line — wind call, dial, hold, group, atmospherics. Every entry flows back into the firearm's history, so the next solve gets smarter the more you shoot.
- Live shot log — Factory, Reload or load development data logging
- Load-development view groups shots by charge automatically
- Session report exports as PDF or shares with the team
Every rifle becomes its own knowledge base.
Each firearm carries its confirmed loads, range sessions, and barrel history. Update one zero and dependent solutions update too. No spreadsheet glue, no hunting through old notebooks.
- Firearm record: cartridge, barrel, twist, sight height, scope click
- Confirmed load library with lifetime velocity stats
- Barrel-change history with full archive view
Solve against your rifle. Not a generic curve.
Range, wind, atmospherics, Coriolis, spin drift — computed against the rifle's confirmed load, not a textbook bullet. Tracks cleanly through transonic into subsonic so the dial doesn't quit on you when the bullet does.
- G7 canonical drag, G1 fallback when needed
- Live atmospherics — temp, pressure, humidity, density altitude
- Per-rifle BC, MV, and zero environment
One platform. Every device.
Set up at the bench on the desktop site. Log on the range with the Android app. Pull up quick stats on mobile web. Same firearms, same loads, same history.
Pair a Kestrel. Pull live atmospherics. Solve fresh.
Bluetooth handshake on the Android app, then one tap pulls pressure, temperature, humidity, and wind into any sensor field — no manual transcription, no out-of-date readings.
