July 15, 2026
This update brings two new ways to explore functions: - Trace points: Tap any curve to see the exact coordinates. Drag the point (or turn the Digital Crown on Apple Watch) to slide along the curve and read (x, y) values in real time — perfect for finding zeros and intersections. - Parameter sliders: Use parameters like a, b, c in your expressions (e.g. a·sin(bx)+c) and drag sliders to watch the graph respond instantly. See exactly how each parameter shapes the function. Also in this version: - New expression engine for smoother graphing and parameter adjustments - Fixed operator precedence for -x² to match mathematical convention - Minor fixes and performance improvements
