Getting Started & Understanding Results

Install or update

Join the Google Play Android beta. Once your tester access is approved, install or update ShotProof through Google Play. In ShotProof, open the bottom Menu (or ⋮ in older builds) → App Updates → Open Google Play. The store shows Update when one is available, or Open when your installed version is current. Restarting ShotProof does not install an update.

Install updates over your existing app. Do not uninstall or clear app storage to update. Keep a complete backup outside ShotProof. Updates become available after Google approves them. Pro and the iPhone app are not released.

Your first target

1. Choose or add your gun. Choose Rifle or Pistol, then select its ammo profile and enter the actual shooting distance.
2. Print the ShotProof target at Actual Size / 100%. Measure the one-inch square on the paper. Use one shot at each numbered bull on the five-bull sheet.
3. Photograph the whole sheet, with the paper flat and all calibration markers visible. Photos save on the phone.
4. Review the calibration and every shot marker. Tap the photo to enlarge it and pinch to zoom. Use FIX SHOT MARKERS for misplaced or missing impacts, then Save Changes. Reopen the target to confirm the correction.
5. Optionally add its matching Garmin ShotView readings. Confirm the selected target and reading count before attaching.

Choose your gun on Home → Past Sessions → open a session returns to saved targets. Older saved target details remain part of that target even if you later change its shared ammo profile.

Find, edit and compare your records

Gun details: tap the selected gun box → Edit Gun. Change its name, caliber, barrel length or notes. Menu → Manage Guns & Ammo opens the same management tools.

Saved loads: choose your gun → My Saved Loads. Search by name or notes, star favorites, or select Rename Load. Names change without changing the gun/load ID or disconnecting past sessions. Historical targets keep the names recorded when photographed.

Past Sessions: search by gun, load, date or notes. Compare Past Targets lets you choose two targets for the same gun and load and see their original photos, dates, distances, MOA and available velocity SD together. Preliminary measurements remain marked for review.

Save confirmation: look for Saved on this phone after a successful target save. A save error means keep the target open and retry.

Quick Tour: open Menu → Quick Tour for the short walkthrough at any time.

What the measurements mean

Group size is the greatest distance between impact centers, in inches. For the five-bull sheet, impacts are aligned by their own aiming centers; the large spacing between printed bulls is not part of the group.

MOA converts that spread to an angle using your entered distance. One inch at 100 yards is about 0.955 MOA; one MOA at 100 yards is about 1.047 inches. Entering the wrong distance changes the MOA result.

Mean radius is the average distance of the impacts from the group's center, in inches. It differs from the greatest-pair group size.

Software checks cover known coordinates, perspective calibration and independent numerical answers. Printed scale, photo quality, lens effects, calibration and your marker review still affect the real target measurement. Compare with the paper target.

Garmin readings and statistics

Import a ShotView export for the selected target. ShotProof uses the raw selected readings, converts m/s to FPS when necessary, and keeps the readings with the target. Direct Garmin Bluetooth pairing is not included.

Average is the arithmetic mean. STD DEV uses population standard deviation (n), matching the current phone app; a single reading does not show SD. SPREAD (FPS) is the highest velocity minus the lowest velocity. This velocity spread differs from the target's group size in inches.

For readings 2800, 2810 and 2820 FPS, the average is 2810, population SD is about 8.16, and velocity spread is 20 FPS. A matching summary from the original Garmin export is retained when available. Older manually entered values remain in the saved record. Check the raw readings and count when comparing older results.

ShotProof flags mismatched targets and differing reading/impact counts. Combined results do not present overlapping Garmin readings as a valid combined SD. Individual velocities are not automatically assigned to particular holes.

Pistol Power Factor

Choose Pistol, enter the bullet weight in grains, and select the USPSA division. Power Factor uses bullet weight × average velocity in FPS ÷ 1000, then drops the decimals. For example, 147 grains × 900 FPS ÷ 1000 = 132.3, displayed as 132. A result of 124.9999 stays 124.

The displayed Minor floor is 125. Open, Limited, Limited-10, Single Stack and Revolver have a Major PF floor of 165; Production, Carry Optics and Limited Optics are Minor-only. Other division and ammunition eligibility requirements still apply.

This is a range estimate. ShotProof uses the average of the attached readings, or your recorded manual average. Official match testing uses actual weighed bullets and the match chronograph procedure, including prescribed three-reading averages and retesting. A range estimate does not establish official match eligibility.

Back up and recover your work

1. Open Menu → Backup & Restore → Back Up Everything. Wait for the save/share screen, then save the file somewhere outside ShotProof, such as Drive or your computer. A file left only in Downloads on this phone does not protect against loss or breakage.
2. Keep the original file. It includes saved photos, markers, results, gun/ammo profiles, attached Garmin readings and the recovery draft. Named target groups are not included.
3. To restore, choose Restore Everything and select the file. Review the confirmation. Existing targets are kept; conflicting records are imported as separate copies.
4. If a restore is interrupted, reopen ShotProof and select the same backup again to resume. Completed records are skipped. Verify several targets and attachments before retiring an older backup.

Large backups take longer. Leave the app open while it works. If a save fails, keep the target open and retry; a success message should appear only after the save is verified. Never uninstall or clear storage as a troubleshooting step before securing a separate backup.

Free backup and planned Pro protection

Manual complete backup and restore remain free. Backup & Restore shows when a backup file was created and separately asks you to confirm you saved it off the phone. Creating a file is not proof it reached Drive or another phone. Reminders flag new records or an older confirmed backup.

Automatic cloud backup and recovery on a new phone are planned Pro benefits. They are not active yet. Keep independent manual backups until the service launches.

What is available

The free Android beta includes rifle/pistol setup, factory-ammo and handload records, target measurement, saved sessions, Garmin file imports, printing, sharing and backup. Pro, public syncing, direct Bluetooth import and the iPhone app are not available. Beta testing continues before a broad launch.

Get help or report a problem

Send Feedback. Include the app version, phone model, Android version, the steps that caused the problem, and whether it happens again after reopening. For a calculation question, include the entered distance or bullet weight and the raw readings used. Attachments are optional; inspect shared files before sending them.
