I am a former user of Geometer's Sketchpad which I find is no longer support on the Mac (was never converted to 64bit I think). So I took a chance on this app and found it to be an excellent substitute. In many ways, this app is easier to use than Sketchpad was. This app is very easy to learn, especially if you have experience using other geometry drawing tools; if not, it's probably a good idea to watch the training videos the developer has provided (with easy links from the help menu). When you click on any function, the app provides, in a message bar at the top of the window, the steps to follow to accomplish the construction. For example, click on perpendicular line and you are told to first click on the line you want the perpendicular to, with all possible candidates highlighted in red. It then tells you to click on an existing point or click a new point for the perpendicular to run through. And you're done. You don't need to remember what order to do each step. All in all, I find the app to be well worth the modest subscription fee being charged.

Best Geometry App

I downloaded this app for my studies, and I am very glad that I did. This is simply the best geometry app there is. Low cost, easy to use, and runs smoothly. It is also updated fairly often, and so far I haven’t found any bugs or glitches. Another thing that I like about this app is how precise it is when drawing. In addition, the appearance of the app changes if your device is on dark mode, which is a feature that many geometry apps (or apps in general) lack. Overall, this is a great app and I would definitely recommend it.

Now, this is a Geometry App!

I decided to get a second degree in math, and I am lucky enought to also lead college supplemental instruction sessions in trigonometry. However, even with some pretty amazing online tools, there wasn't an app I could find that made creating and working with geometric shapes easy.

This one does just that!

A big kudos to BleezWorld. I already love the app, and look forward to where it is going!
