Katamuki Checker
Posture & photo angle records
$0.49 · Designed for iPad. Not verified for macOS.
Record posture and movement. Place 3–5 points on a photo, save an image with angles, and compare two records side by side.
Record posture and movement in photos and videos, then check angles on the image. Capture a photo or import one from your photo library, place and adjust points, and save or compare your records.
CHECK ANGLES ON PHOTOS
• Measure an angle with 3 points, or consecutive angles with 4 or 5 points.
• Check tilt relative to horizontal or vertical.
• Zoom in and adjust point positions.
• Use automatic pose detection and edit points manually.
SAVE MEASUREMENT IMAGES
Save a photo with the selected measurement’s lines and angles inside the app. Each saved image is separate from the original photo record, so it preserves the view at the time of saving even if you later edit that record. Saving inside the app does not add an image to your photo library.
REVIEW AND COMPARE RECORDS
Browse photos, videos and saved measurement images. Compare two photos or measurement images side by side, with independent zoom and pan. Match measurements of the same kind to check angle differences.
EXPORT WHAT YOU NEED
Export saved measurement images to Photos. Preview comparison images as Photos only or With details before exporting. Export measurement records as PDF reports and CSV files, or use the system share sheet.
SUPPORT FOR CAPTURE
Capture photos and videos with optional grid lines and an upright holding guide. Hold the device vertically in portrait orientation: the guide reads 0° when upright and turns green within 3°. Choose which overlays to show and save in Capture settings.
No account is required. Photos, videos, pose detection, angle calculations and records are processed and stored on your device. The app does not send this data to the developer and contains no advertising or tracking.
Katamuki Checker supports recording and observation. Image angles depend on the camera viewpoint and point placement. It does not provide a medical diagnosis or replace treatment decisions.
