Hey PH! 👋 Built Nexmetra to fix what's wrong with most free online tools — ads, clutter, and inaccurate measurements. Focused hard on keeping every tool clean, fast, and genuinely easy to use. 🔹 Ruler — auto-calibrates to your screen, tracks history, lets you drop markers on exact points 🔹 Protractor — 180°/360° modes, precision up to 3 decimals, deg↔rad toggle, export canvas + history, overlay mode (measure angles directly on an image), ray mode (draw angles from 3 points) 🔹 Aspect Ratio Calculator — instantly find the missing height or width for any ratio, plus check a file against your chosen ratio and preview how it crops across social platforms 🔹 Aspect Ratio Finder — upload any file to instantly get its ratio, then test other files against that same ratio No ads, no sign-up, no clutter — every tool is one clean screen, built to feel effortless. Everything runs client-side, nothing uploaded to a server. Would love feedback, especially on the protractor's ray mode!
