About this app

Counting a shotgun pattern by hand takes forty minutes and a marker. PatternPro takes a photo of the target, counts the pellet hits, and gives you the numbers.

Photograph the target, let the AI mark the pellet holes, then correct anything it got wrong. You get point of impact, percentage inside the standard 30 inch patterning circle, spread, pattern shape and quadrant balance, ready to export as an image.

HOW IT WORKS
1. Photograph your target. The camera shows a level indicator, because an angled shot is what ruins a count.
2. The app marks the hits. It will miss some and add a few that are not there, so tap to add or remove. The final count is yours.
3. Read your pattern. Point of impact, pattern percentage, spread and shape.

WE COUNT. YOU CORRECT.
Automatic pellet counting is an estimation tool, not absolute truth. It gets you most of the way and you correct the rest. That is why the correction step exists, and why the number you export is one you have checked.

WHAT YOU GET
- Pellet count and pattern percentage inside the 30 inch circle, or 75 cm at 35 m
- Point of impact against your aim point, so you can see where the gun actually shoots
- Pattern spread, pattern shape and quadrant balance
- A density map showing where the pattern thins out and where the gaps are
- Choke and load comparison, side by side
- Full patterning history by gun, choke, shot size and distance
- Export a clean pattern card as an image
- Works offline at the pattern board

SETTLE THE CHOKE ARGUMENT
Save every target and compare chokes, loads and distances side by side. See which combination actually patterns best in your gun rather than what the box claims. Turkey loads, waterfowl steel, TSS, buckshot and clays all measure the same way, and the answer is yours rather than the manufacturer's.

BUILT FOR THE RANGE
Pellet counting runs on your device where supported, so it works with no signal at all. No bars at the pattern board is the normal case, not the edge case.

TRACK THE SEASON
Every pattern is saved with its gun, choke, shot size and distance. Watch your point of impact across a season and catch a drift before it costs you a bird.

ASK ABOUT YOUR OWN DATA
AI Insights answers questions about the targets you have saved: which load patterned tightest, whether your point of impact drifts, what changed between two sessions. It reads a numeric summary of your own results. Your photographs and your written notes are never sent.

WORKS SIGNED OUT
Analysing, correcting, saving and exporting need no account. Sign in only if you want Pro to follow you to a second device, a backup of your saved targets, or AI Insights. You can delete your account, and everything in it, from inside the app at any time.

METRIC AND IMPERIAL
Distances and circle sizes follow your region: a 30 inch circle at 40 yards, or 75 cm at 35 m. Available in English, Spanish, French, German, Italian, Portuguese, Polish, Japanese, Chinese, Arabic and Urdu.

PATTERNPRO PRO
Unlimited saved history, Insights and Compare, pattern export, photo backup to the cloud, and a larger monthly AI allowance. Monthly, annual, or a one-time lifetime unlock. A year costs less than one box of TSS.

Download PatternPro and find out what your shotgun actually throws.

Shotgun patterning for turkey, waterfowl, upland, buckshot and clays. Pattern board analysis, shot pattern testing, pellet counting, choke testing, point of impact and pattern density from a photograph of a paper target. Run a pattern test at 40 yards or 35 metres, compare full, improved modified, modified and cylinder chokes, test turkey loads and TSS, and keep a shotgun patterning log across the season.

PatternPro is a measurement tool for sport shooting and hunting. It does not sell firearms, ammunition or components.
Know what your gun throws. Pellet count, point of impact, choke tests.
