About this app
Find your ring size in seconds — no physical sizer needed. True Ring Size turns your phone into an accurate ring sizer that works fully offline. Two ways to measure: • Ring on screen — place a ring you already own on the display and resize the circle until it matches. • Finger on screen — line up the guides to your finger and read the size instantly. Calibrate once with any bank card for real-millimeter accuracy, then convert between US, UK, EU, Japan, China and Russia sizing — by diameter or circumference, in mm or inches. Why True Ring Size: • 100% offline — no internet permission, nothing leaves your phone • Free forever — no subscription, no in-app purchases • No ads, ever • No account, no tracking, no data collection • Save sizes for the whole family — perfect for surprise gifts and engagement rings • Full conversion chart for every country system Whether you are buying an engagement ring, a wedding band, or a gift, True Ring Size helps you order the right size online with confidence. Note: on-screen measuring depends on your screen; calibrate with a card and measure twice for best results.
