FitCheck

You already know the feeling. The label says M, you own three other things labelled M, and none of them fit the same. FitCheck reads the size chart the shop has already published on the product page, compares it with your measurements, and tells you which size will actually fit — before you order. WHAT IT DOES • Works on Myntra, AJIO and H&M India • Shows a recommended size in the browser side panel, with a breakdown by bust or chest, waist, hip and length • Tells you which parts will be snug, which will be roomy, and by how much • Says "I can't tell" when the chart is missing a measurement, instead of guessing SET UP WITHOUT A TAPE MEASURE Most people don't know their bust, waist and hip, and that's where sizing tools lose them. You don't need them. Open something you already own in the right size and FitCheck can build your profile from that garment's own chart. NO AI, ON PURPOSE Sizing is arithmetic. Your favourite shirt measures 42cm across the chest, this one measure 39cm, that's a 3cm difference and 3cm matters. There is no judgement in that calculation, and a model that can be confidently wrong about a number has no business in it. NOTHING LEAVES YOUR BROWSER FitCheck makes no network requests at all. No server, no analytics, no account, no sign-in. Your measurements are stored on your device and never sent anywhere. The full source is public, so you can check that rather than take my word for it: github.com/ritikadas98/fitchecker WHAT IT CANNOT DO YET Roughly one page in three has a chart that's missing a measurement, or published as an image. On those, FitCheck tells you it can't work it out instead of guessing. There's a one-tap way to report a page like that, and those reports are what fix it. Requires a Chromium browser — Chrome, Edge, Brave, Arc, Opera or Vivaldi.
