Calculate your hold.
Don't guess it.
Drop, wind, spin drift, Coriolis and shot angle — solved on your phone, in the field, with no signal. For PRS, IPSC shooters and hunters.
Three steps to your hold
Pick your setup
Rifle profile (zero, twist, scope height) + ammo from the database or your own load.
Enter conditions
Distance, wind (clock position), temperature and pressure — or import weather from GPS.
Read the solution
Correction in MOA or MIL, trajectory table, chart and holdover on the reticle.
Numbers you can trust
Point-mass RK4 engine
Full trajectory integration with Runge-Kutta 4 at a 1 ms step and ICAO G1 and G7 drag tables — not rough rule-of-thumb formulas.
± accuracy under 1 mm at 1000 m
Every correction, not just drop
Wind drift from clock position, gyroscopic spin drift, the Coriolis effect by latitude, shot angle (Rifleman's Rule) and air density from temperature, pressure and altitude.
› Coriolis: 3–8 cm of drift at 1000 mYour whole arsenal in your pocket — offline
No signal at the range or in the field? No problem. The ammo database, rifle profiles and all calculations run 100% on the device. Your data stays with you.

Everything under one thumb
Trajectory table
Drop, drift, velocity, energy and time of flight at every distance.
Flight chart
Visualises the bullet path and the zero crossing.
Reticle / holdover
The correction plotted on a round scope reticle with a target silhouette.
DOPE card
A range card ready to print / export for the field.
Rifle profiles
Zero, twist, scope height, click value, notes.
Ammo database
~340 factory loads + add your own.
Weather import
Temperature, pressure and wind from your GPS location.
10 languages · units
Metric and imperial, PL/EN/DE/FI/SV and more.
Take it to your next range day

Built on physics, not marketing
ICAO G1/G7 tables
Standard drag tables (81 and 85 points) with interpolation — the same ones the industry uses.
Runge-Kutta 4
A 1 ms step instead of simpler Euler — more accurate for the same compute time.
Established literature
Correction formulas follow recognised external-ballistics literature (incl. Litz).

Before you download
Does the app work without internet? +
Yes — all calculations, the ammo database and rifle profiles run 100% on the device. Internet is optional, only for importing weather from GPS.
What about my data and privacy? +
Your data (profiles, ammo, sessions) stays on your phone. There's no account or cloud. Android Auto Backup to your private Google Drive is enabled, so you recover your setup on a new phone.
G1 or G7 — which drag model? +
Both. You choose the model per load, and for match bullets (e.g. .308, 6.5 CM) the more accurate G7 is suggested by default.
Is it free? +
Yes. Full trajectory solving, the database, profiles and reticle are free. Pro unlocks advanced corrections (Coriolis, cant), holdover, the DOPE card, the training journal and field tools.
Which units does it support? +
Metric and imperial — metres/yards, m/s/fps, cm/inches, hPa/inHg, MOA and MIL. Switch with one tap in settings.
Which platform? +
Android — available on Google Play. Installing from the store also gives you automatic updates.
