Great PreViz Tool

I’m currently developing a shot list and storyboards for a short film, and this app makes my life so much easier. Easy to use and works really well.


-A great in-app purchase would be expansions to the people and objects we can use. e.g. People sitting, running, kneeling, etc. and basic furniture like chairs and tables.

-I can’t figure out how to remove someone from the frame without just force quitting my app. Is there an easy way to reset the frame that I’m missing?

My storyboard artist and I have been taking weird, awkward selfies to try and figure out 3D perspectives for her to reference as she makes her 2D drawings, so this app is a lifesaver. A few updates will make this a truly indispensable tool.

Thanks so much for the review and the feedback!

- To delete a character swipe across them (We know this isn't easy to discover and are considering a tutorial or reworking the feature)
- We hear you on suggestions for the models and plan on adding those. If you have other model requests please send them to We want the asset library to be driven by user's needs.

We'd love to see what you're creating. Feel free to share #blocker

5 Stars! Top class previz tool.

Excellent app for shot blocking and story-boarding. I personally use it all the time.

Include more characters (real/fantasy), props, weapons, interiors/exteriors. Animated characters with simple walking, running and some animated gestures will be super cool.

Seems great

Maybe it’s just mine, but the camera freezes before I can actually set up a shot. I get blurry pictures or just a shot that’s not correctly framed. Like the 3D models because I cannot draw!
