DryFire Pro turns your phone or tablet into a true-to-size 10m air pistol target for dry-fire practice at home.

Phones and tablets don't report their real screen size, so most target apps show an image at the wrong physical size. DryFire Pro fixes that: you calibrate the display once against a bank card, a sheet of A4, or a ruler, and every ring is then drawn at its exact millimetre size — rescaled correctly for whatever distance you actually have room for, from 3 ft up to a full 10 m.

CALIBRATE ONCE, TRUST THE SIZE
• Match an on-screen bar to a bank card's short edge, an A4 sheet, or enter a ruler measurement directly
• On iPhone, a known-device table proposes a scale and asks you to confirm it against a real card
• The scale in use, where it came from, and a Recalibrate link stay visible under the target — a wrong scale is never silent
• Reset and recalibrate at any time

PRACTICE AT THE DISTANCE YOU HAVE
• Any practice distance from 3 ft to 10 m; ring sizes rescale to match
• Drag the target up or down to clear a camera cutout or match how your device is mounted — the position is remembered
• Optional dotted alignment line from the top of the screen down to the target
• Show or hide the inner rings

THREE DISPLAY MODES
• Paper — classic black rings on white, with a choice of paper tones
• Range HUD — dark, electronic-scoreboard styling
• Night — deep red for low-light practice; red light preserves dark-adapted vision far better than white or amber

BUILT FOR REAL SESSIONS
• Hardware brightness slider (5–100%) in the controls panel, restored to your original setting when you leave
• The screen stays awake for the whole session — no auto-lock mid-string
• Optional start cue in Night mode: a soft "ready" tone, then a "fire" tone after a random 1.5–4 second delay, so you can keep your eyes on the target instead of a countdown
• Portrait or landscape, phones and tablets

PRINT A REAL TARGET
Export the same target as a PDF and print it at 100% / Actual Size. The PDF is laid out in real millimetres, so it needs no calibration of its own. A printed 100 mm ruler on the page lets you check that your printer didn't rescale it — if that ruler doesn't measure 100 mm, your print settings are wrong, not the target.

WHAT THIS APP IS NOT
DryFire Pro is a target and a timing cue — nothing more. It does not detect shots, score hits, or use your camera or microphone. It is built for dry-fire practice: sight alignment, trigger control, hold and handling drills, without ammunition. Always follow your range's rules and the firearm safety laws where you live.
