### 2/5 — Interface is Horribly unclear

*2025-09-23, version 1.0.0*

The idea of this app has so much potential but it desperately needs a completely new User interface. So cluttered, not labelled, and unintuitive.

### 1/5 — Terrible App

*2024-11-10*

Really clunky and unintuitive interface. Does not allow me to move panels from inconvenient position on the left and panels overlap so I can’t see multiple panels at once. Would not recommend.

### 1/5 — Awful

*2024-01-25*

I could not manage to get this app to work at all. It’s very clunky and it all together totally worthless.

### 5/5 — Pretty cool

*2022-07-26*

Neat utility!

1) Is there a way to Synthesize all the poses on the same branch and in order, please?  It keeps generating by splitting the poses across branches and I can’t image under what circumstances that solution could be useful.
2) Can we please rotate the whole scene with a new multitouch gesture?

### 5/5 — Amazing

*2022-02-13, version 1.0.0*

This is an amazing app. Very simple and clever design. I hope it could simulate 5 bar linkage too.

### 5/5 — Very sleek app for mechanism design

*2016-11-28*

Great utility tool for any design engineer's toolbox
