Quick Graph is a powerful, high-quality graphing calculator for iPhone and iPad, in 2D and 3D. "The app you need to survive the next semester." -- Gizmodo Type an equation and see it right away, written in math notation and drawn in a graph you can move, zoom and rotate with your fingers. Explicit and implicit equations and inequalities, in cartesian, polar, cylindrical and spherical coordinates, all fast and beautiful. What's inside: - 2D and 3D graphs with a clean, full-screen design. - 3D surfaces drawn with Metal: smooth shading, transparency, wireframe, and zoom that fills the screen. - Adaptive 2D drawing with exact roots and extrema and clean asymptotes. - Equation groups: show, hide and move several equations together, with a shared n. - Annotations with Apple Pencil or your finger on 2D graphs. - A math keyboard with functions, derivatives and more on each key. - Hyperbolic and inverse functions, min, max, if, derivatives. - Axes in decimals or multiples of π, and independent zoom on each 2D axis. - A library of example and saved equations, including groups. - Share as a link, image or text; copy and paste equations; drag them between windows. - Light or dark appearance, multiple windows on iPad, and support for iPhone Duo. Up to 6 equations can be shown at once in the free version. The Advanced Features, a single one-time purchase with no subscription, add: - More than 6 equations. - 2D and 3D implicit equations and inequalities. - The variable n with a slider, to animate your graphs. - 2D tracing with roots, extrema and intersections. - Value table. - External display support. - Decimal / π axes and polar range settings. No ads, no subscription. Please visit the website for more details.

1. Measurement data (CSV file) can be plotted in 3D. • Interprets delimiters other than commas: tab(\t), space(\s) and so on. • Imports the 4th element, which is used as density, concentration and so on. • Imports the value represented with exponential notation "0.0E±0", which is outputted by Excel. • Internal processing in float type, which has a range of ±1E-38 to ±1E+38 with a precision of 6 decimal digits. 2. You can import CSV file in three ways: When completing within one device (iPhone/iPad/Mac). • Create a text file with an application (Notes, Textor, etc.) on the device. • In the application, tap "share button" and then choose “3dDataPlot”. Transfer from Mac to iPhone/iPad • Connect your device (iPhone/iPad) to your Mac via USB cable. • In Finder on your Mac, select the device in the left sidebar and click "File" on the button bar at the right. • Drop a text file into “3dDataPlot” folder. Import from iCloud • Sign in to iCloud.com from browser (Safari, Chrome, etc.) on your Mac. • Select “iCloud Drive”. • Drop a text file into “3dDataPlot” folder.

Verdict
The clearest difference is review sentiment: Quick Graph at 94% against 3D Data Plot's 0%. Quick Graph also leads on update cadence (every 5 months vs every 17 months). 3D Data Plot's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
