Roundness Checker

Roundness Checker is a simple visual inspection tool for checking circular shapes with your iPhone camera. Align the object with the on-screen guide circle, use the live level readings to keep your phone steady, then freeze the view for closer inspection. The app is designed for quick, practical checks when you want to compare a real circular edge against a clean reference circle. Features: - Live camera guide circle - Front/back and left/right level readings - Center alignment dot - Freeze and unfreeze inspection mode - Point-down guidance for proper camera positioning - Clean full-screen visual checking workflow Roundness Checker is a visual aid, not a certified measurement instrument. For safety-critical or precision-critical work, confirm with proper measuring tools or a qualified professional. Example uses: - Checking wheel rim roundness - Inspecting round parts, rings, discs, or plates - Comparing circular edges during repair or fabrication - Quick workshop or garage visual checks
