About this app

Fascinatingly simple. Simply fascinating. sketchometry is a different kind of dynamic math software. You draw with your finger on your iPhone or iPad. sketchometry automatically converts these (finger) sketches into exact geometric objects. Mathematics becomes an experimental subject. No ready-made results are presented, learners are encouraged to go on a journey of discovery by themselves.

What's new

Version 26.3 · Jun 12, 2026

With version 26.3, sketchometry receives an update that significantly improves working in the area of analysis. The new coordinate system ensures that the x- and y-axes now use a consistent ticks distance and behave more coherently overall. Another major step forward is the improved term handling. Terms are now simplified, making functions clearer and easier to read, and significantly improving the handling of more complex expressions. In combination with this, function terms are now also evaluated dynamically, so changes made via sliders are directly reflected in the term beside the graph. It is also now possible to drag function graphs with your finger. This feature must be enabled in the graph's properties. Function graphs can now also leave traces. This is particularly useful in conjunction with the slider for displaying family of functions. In addition, an issue in the iOS help system has been fixed that previously caused display problems. Beyond these changes, the update includes many additional improvements and internal adjustments that further enhance stability and performance.
