Six data points. One question: is there a trend? LittlePlotter gives you a fast, beautiful answer. Type your values, swipe through eight curve types, and share a clean chart — in the time it takes to unlock your phone. No spreadsheet. No setup. No noise. EIGHT FITS, ONE SWIPE AWAY LittlePlotter covers the curves you actually reach for: • Line Segments — connect your points exactly as they are • Cubic Spline — smooth interpolation through every data point • Linear, Quadratic, Cubic — least-squares polynomial fits • Exponential, Logarithmic, Power Law — for data that grows or compresses nonlinearly The fitted equation is shown directly on the chart. If a fit can't be computed — wrong domain, too few points — the chart explains why. DESIGNED FOR SPEED The chart fills the entire screen. A single button opens the data table; edit your values and the chart updates live behind the sheet. Swipe left and right to move between fits, up and down to switch between fit families. Your data is saved automatically so you pick up exactly where you left off. SHARE-READY OUTPUT One tap exports a clean, high-resolution chart to your Photos. Press and hold for more: share via AirDrop, Messages, or any app, or copy directly to the clipboard. WHO IT'S FOR LittlePlotter is for anyone who works with measurements and wants a fast, clean answer: researchers checking a calibration curve, students visualising lab data, engineers sketching a trend on the fly, teachers making a quick diagram. If you've ever opened a spreadsheet just to plot six numbers, this was made for you.
