Embroidery Tension Check

Review the back of a multi-needle embroidery H-test without estimating every lane by eye. Embroidery Tension Check divides one clear photo into 1–20 needle lanes, measures the visible center bobbin band, and groups the lanes into check, tighten, loosen, or unreadable states. Adjust the lane inset when the stitched columns do not line up, then retest only the lanes that need another look. BUILT FOR A CONTROLLED H-TEST - Choose the number of stitched needle lanes - Import a photo or capture one with the camera - Review each lane and its visible bobbin-band percentage - Adjust lane alignment and analyze again - Run a focused retest and compare the new result TRY THE LABELED DEMO The included six-lane example shows the complete reading and retest workflow at no charge. Lifetime Pro is a one-time, non-consumable purchase that unlocks analysis of your own photos, all 1–20 lanes, alignment, and focused retesting. No subscription. Restore Purchases is available on the purchase screen. LOCAL AND PRIVATE Analysis runs on your iPhone. No account, analytics, advertising SDK, or cloud upload is used. Selected photos remain in the current session and are cleared when you start over or close the app. Purchases are processed by Apple. IMPORTANT This app is a visual measurement aid for the back of a standard H-test stitch-out. It does not diagnose an embroidery machine or prescribe knob turns. Confirm your bobbin baseline and adjustment direction with the machine or tensioner manual, use a consistent test design and materials, and verify the result on a new stitch-out before production.
