Description

Know exactly how good your group was.

RoundKeep Zero turns a photo of your target into an accurate shot group measurement. Measure group size in inches and MOA without a caliper, ruler, or manual marking.

Whether you're zeroing a rifle, testing ammunition, tracking accuracy, or comparing loads, RoundKeep Zero helps you analyze targets quickly and consistently.

HOW IT WORKS

1. Print one of our free targets or use your own.
2. Take a photo with your phone.
3. RoundKeep Zero detects your shots, scales the image, and calculates group size, extreme spread, and MOA.

ACCURATE TARGET SCALING

Our printable targets include built-in reference markers, allowing the app to scale your photo automatically - even when the image is taken at an angle.

No drawing reference lines. No entering measurements. No guesswork.

Using a target without markers? RoundKeep Zero can use bullet-hole diameter as a fallback reference for measurement.

AUTOMATIC SHOT DETECTION

On-device computer vision automatically detects shot holes and measures your groups.

Need to make adjustments? Add, move, or delete shots with a tap, assign shots to groups, and fine-tune the scale. Measurements update instantly.

FEATURES

• Measure shot groups in inches
• Automatic extreme spread calculation
• Target analysis for rifles, pistols, and other firearms
• Works with your distance and caliber
• Save targets to your personal library
• Review previous shooting sessions
• Share clean, annotated target images
• Fully editable measurements and shot detection

FREE PRINTABLE TARGETS

Print our free marker-enabled targets directly from the app for the fastest and most accurate measurements - or use your own targets.

PRIVATE BY DESIGN

All target analysis runs on your device. No account needed. No AI.

Print. Shoot. Snap. Measure.
