## Most critical reviews (10 lowest-rated)

### 1/5 — Junk doesn’t not even let you write with a pen

*2019-03-26, version 3.4*

This app is so bad! I do not recommend this for geometry. Bad, doesn’t even let you work with a pen.

### 1/5 — Constantly Crashes in iOS 9

*2016-03-30, version 3.3*

When drawing circles from a central point they often just go away as soon as you let go. There are weird hollow points added near intersections of circles, and I tapped the arrow in the left corner and now every time I open the app it says "Upgrading files" then promptly crashes.

### 1/5 — It's bad

*2015-10-27, version 3.2.1*

Seriously, you do not want to try it.

### 2/5 — Good app, bad problem

*2013-09-28, version 2.0.1*

This app is good but the huge problem is that it crashes very often that's why I rate 2 stars.

### 3/5 — This software was developed by a 17 year old.

*2019-08-28, version 3.4*

Yup, I can believe that.

### 3/5 — Clashes when I try to close one sketch and create another

*2018-09-15, version 3.4*

I need to delete this app then download again every time I close the sketch.

### 4/5 — Hmmm

*2019-12-19, version 3.4*

I can’t seem to make an isosceles triangle, plz help

### 4/5 — Great for drawing Graph Theory diagrams.

*2013-12-05, version 2.1*

Although it is intended as a geometry app, it is the best touch screen editor to draw Graph Theory finite simple graphs (one can do loops and directed edges). A real joy.

The new Tikz code generation works, but it can be improved (the points are poorly labelled).

### 4/5 — Awesome

*2013-05-01, version 1.3*

Really enjoy the simplicity of this program. Works very well for making a quick drawing to communicate plans with others!

### 5/5 — This app saved my marriage

*2015-12-01, version 3.2.1*

This app is the best thing that has ever happened to me. I used to be lost and had no direction in my life, but once I used this mesmeric geometric sketch pad, my parents finally love me. I currently hold the high score in isosceles with 223,277,188 crashes to date. This app never fails to crash right before you turn in a 300 point assignment. Thanks to the designers!

### 5/5 — Incredibly useful

*2014-10-06, version 3.0.1*

Finally, an app that allows me to modify geometry problems seen in the textbook so that they are clearer for my students who have disabilities. Also a great way for students who have motor problems to participate in constructions! Wonderful app. I added the premium feature pack because I was using it so much, but the free app stands on its own as a high utility, well thought out tool.

### 5/5 — 1st to review

*2012-12-02, version 1.0*

I am the first to review. Good job on the app but we should be able to keep more than two sketches.  CMHS and CMM
