The breakdown.
Performance broken down by ammo, distance, and firearm. Which load is actually shooting tightest? Which rifle has improved since the new optic? The breakdowns answer it.

Three Steps. One Target.
-
01
Shoot
Start a session. Log the range, the firearm, the conditions — whatever you'd write in a paper book. An optional timer and audio shot detection are there when you want them.
-
02
Photograph
Capture the target right in the app. That's all there is to it.

Analyze
Machine learning does the heavy lifting on-device, logging your shots in seconds with easy manual adjustments if needed. The session lands in your history, where patterns surface that a paper book could never show you.
Multi-discipline
by design.
Target Detect was built for the precision shooter and the IPSC shooter, the bullseye match and the police qualification course. It scores NRA bullseyes, Appleseed targets, IPSC silhouettes, qualification targets — most paper targets you'd hang on a backer.
Machine learning does the hard part — finding shots and marking them — so scoring runs at the speed of the next magazine, not the speed of a pencil. That makes it practical to track disciplines that used to be too tedious to score by hand.
“You can't improve what you can't measure.”
Measurement
Finally, real accuracy data.
Without feedback, every shooter plateaus.
Group size measures one session. CEP measures progress.
A 3-inch group from three shots and a 3-inch group from fifteen tell very different stories — but they look identical on a scorecard. Target Detect's primary metric is Circular Error Probable, reported twice over: from your point of aim (accuracy) and from your point of impact (precision). Both hold up across sessions, disciplines, and shot counts. Group size is tracked too — for completeness, not comparison.
Aggregate a season of practice into numbers that actually mean something. Then watch them move.
Simple by design.
Target Detect already knows the dimensions of standard targets. Just pick your target type, log your distance, and snap the photo — no reference coins, no manual scaling, no calibration required. Scoring, statistics, and history happen on their own.
The whole point is that measuring your accuracy on every target is finally practical, not a paper-and-pencil chore.
Reports
Tables. Plots. Trends.
Target Detect doesn't just record your sessions — it dissects them. Your data shows up three ways: questions answered, geometry visualized, history tracked.
The geometry.
Shot placement on the target, MOA spread analysis, and overlaid groupings that compare different ammo types side by side.
The long game.
Scores, shot count, flyer rate, and CEP over your whole history. Accuracy (relative to point of aim) and precision (relative to your actual center of impacts) are reported separately — because they're different problems with different fixes.
Across your devices
Practice on iPhone.
Study on iPad and Mac.
Target Detect isn't a resized iPhone build. The iPad and Mac versions use purpose-built split layouts — the target on one side, the data on the other — so the dense reports finally have the room they were drawn for.
Plots, full breath.
Shot placement, MOA spread, ammo-type overlays — the kind of geometry that wants space.
Trends, full season.
A year of CEP across the top, the session list beneath. The patterns reveal themselves on a bigger screen.
Privacy
Your data stays on your devices.
Neither Target Detect nor any third-party service has access to your scorebook. No analytics, no advertising or attribution SDKs, no third-party services of any kind. Target Detect doesn't phone home, doesn't ship logs to a backend, and doesn't ask you for an account.

FAQ
Questions, answered honestly.
Is my data end-to-end encrypted in iCloud?
Apple's standard encryption protects it in transit and at rest. If you use Advanced Data Protection on your Apple ID, it's end-to-end encrypted as well.
How does the app score my targets?
A machine learning model trained specifically on shooting targets finds the shots and scores them automatically. The model runs entirely on your phone — your photos are never uploaded anywhere — and every shot can be moved, added, or removed manually if you want to fine-tune the result.
What target types are supported?
Target Detect supports around 90 paper targets covering most major disciplines:
- NRA Pistol — B-2 through B-8, B-16, B-27, B-29, B-34, AP-1, AP-2, TQ-6, TQ-7
- NRA International Pistol — B-11, B-17, B-19, B-33, B-35, B-37, B-40
- NRA High Power Rifle — MR and SR series (MR-1, MR-31, MR-52, MR-63, MR-Target, SR-1, SR-3, SR-5, SR-21, SR-42, SR Military, LR)
- NRA Smallbore Rifle — A-series and USAS-50
- IPSC — Major and Minor at full, 1/2, and 1/3 scale
- ISSF — 10m, 25m, 50m, and 300m rifle and pistol targets
- Law Enforcement qualification — QIT-99, QIT-03, and TQ-15/16/19/20/21/22
- Appleseed — AQT Stages 1–4 (including 100/200/400 yard variants) and PQT Stages 1/2/5
- Generic round, square, and silhouette — round in seven diameters from 2 to 12 inches, plus generic square and 12×18 silhouette and oval
The full set is in the target picker on the Shoot screen. If you regularly shoot a target type that isn't included, email us and we'll consider adding it.
What if my target photo is at an angle or poorly lit?
The in-app camera includes perspective correction and lighting filters for cleaning up awkward shots — there when a photo needs help before scoring.
What is CEP and why use it instead of group size?
CEP (Circular Error Probable) is a statistical measure of accuracy — the radius of the circle that contains a defined share of your shots. Unlike group size, it isn't thrown off by a single flyer and it's comparable across different shot counts and sessions. That means a three-shot string and a fifteen-shot string can be measured on the same scale, and a year of sessions can be aggregated into trends that actually mean something.
What's different about the Flyer report?
Unlike standard apps that use easily distorted standard deviations, Target Detect uses the modified Z-score with Median Absolute Deviation (MAD) — a robust-statistics method where the baseline can't be biased by the outliers it's identifying. Useful when you want to track diagnostic patterns (technique slippage, equipment issues) separately from your CEP trend.
Can the developer see my scorebook?
No. Target Detect syncs through your own iCloud account using Apple's CloudKit. The developer has no API path to read what you store. The only thing we ever see is an image you choose to attach when emailing for support.
Do you collect analytics or use third-party services?
No. The app doesn't phone home — on launch, in the background, or otherwise.
Is there a subscription?
No. Target Detect is a one-time purchase from the App Store. Buy it once, own that copy.
Will I have to pay for future updates?
No. Every update to Target Detect is included with your one-time purchase — new features, design refreshes, iOS compatibility, all of it. Buy it once; that's the deal forever.
Does it work without internet?
Yes. The app runs entirely on-device. Internet is only needed if you want iCloud sync between devices.
Does Target Detect use my location?
Only if you choose to enable it. With location turned on, the app can recognize which range you're at and prefill the range field for new sessions — that recognition happens entirely on your device. Location is off by default and never leaves your phone.
Can I export or back up my scorebook?
Yes — two separate features for two different needs:
- Export produces CSV files (shot data) and PNG files (target images) for use outside the app — open in a spreadsheet, share, or print.
- Backup & restore produces a JSON archive of your full scorebook (data and photos). iCloud already covers the common case automatically — lose your phone, get a new one, everything's there. Backup/restore is for what iCloud can't do: moving across Apple IDs, archiving offline, or seeding a fresh install.
What happens to my data if I uninstall?
It stays in your iCloud — that's yours, not the app's. Reinstall on any device signed into the same Apple ID with iCloud enabled, and your scorebook syncs back. You can also wipe it whenever you want from Settings → Apple ID → iCloud → Manage Account Storage.
What devices does it run on?
iPhone or iPad running iOS 18 or later, or a Mac with Apple Silicon.
