01
Capture the motion
Mount the SteadyArc sensor — or use your phone's IMU to start today. It streams the angular motion of your hold and press at up to 1 kHz over Bluetooth LE.
Dry-fire · Live-fire · Sport shooting
Master the shot before it breaks.
SteadyArc reads the micro-motion of your hold and trigger press, scores every rep honestly, and turns it into drills you can actually feel improving. No targets to count. No guesswork. Just the truth about your fundamentals.

60 seconds
See it in motion
From trigger to score to coaching cue — the whole loop, captured from the real app.
The loop
Four steps between you and a cleaner break
02
Score it honestly
Every press is broken into hold stability, press movement and smoothness — then blended into one composite you can't game by faking a single number.
03
See the tendency
A crosshair trace shows exactly where the muzzle drifted as the shot broke — down-left, high-right — so you fix the cause, not the symptom.
04
Train with intent
Drills and guided courses turn raw data into a plan. Chase pass thresholds, build consistency, and watch your 30-day trend climb.
Shot grouping
Watch your group tighten
Every press lands on a crosshair target plotted from real muzzle motion. Consistency, average, and a plain-language tendency tell you whether you're drifting — and which way.

- Per-session consistency (±)
- Direction-of-drift readout
Progress
Proof you're getting better
Sessions are saved on-device and charted over time. Your best, your recent average, and a trend you can show your coach — all of it yours to keep and export.

A score you can trust
One number.
Impossible to fake.
Most trainers hand you a single score you can chase by gaming one variable. SteadyArc blends three independent fundamentals — and shows every one of them. Tighten one by sacrificing another and the composite tells on you.

Do I need the sensor to start?+
No. SteadyArc runs today using your phone's built-in motion sensors — start training and scoring reps for free. The dedicated sensor adds higher-rate, frame-mounted capture when you want to go further.
Is this for dry-fire or live-fire?+
Both. SteadyArc is built for dry-fire practice and sport/competition shooting — it measures the motion of your hold and trigger press, which matters whether or not the gun goes bang. It is a training and analysis tool, not a coaching authority on technique.
How is the score calculated?+
Each press is broken into three independent fundamentals — hold stability, press movement, and smoothness — then blended into one composite (50/35/15). Every component is shown, so the number reflects real fundamentals rather than one gameable metric.
Who owns my data?+
You do. Sessions are stored on your device and exportable as plain files. Pro adds optional cloud backup, but your data is never locked in or sold.
What does Pro cost and can I cancel?+
Pro is billed monthly or annually through Lemon Squeezy and you can cancel anytime from your dashboard. There's a 14-day money-back guarantee.
When does the hardware ship?+
The founder run is in development. Reserving a unit places a fully refundable deposit and secures founder pricing — you're charged the balance only when it's ready to ship.
Your next rep is data.
Train smarter from the very first press. Free to start — no sensor, no excuses.
