"Love it, gotta have it"
"The best, hands down, 4K video camera app!!!"
"This app has some serious caliber... Automation is the most amazing part in this app."


Guerrilla Filmmaker has features that no other video recording app has. We also designed the interface for quick control using touch gestures. To help you get the most out of Guerrilla Filmmaker, every feature is demonstrated through an extensive set of in-app instructional videos.


Guerrilla Filmmaker is the only video camera app that lets you automate any camera function (focus, exposure, white balance, zoom) so that you can plan your shot, playback your automation sequence and record hands free.

Take full control by setting exact focus, exposure, white balance and zoom points and dial in the timing.

Set up a pull focus sequence from one subject to another. Automate changing exposure as you track from indoors to outdoors. Create any automation sequence you can imagine.


Use one of the built in aspect ratios including Moondog anamorphic or create your very own.
Support for image flip, rotation and anamorphic squeeze to allow building aspect ratios for any custom external lens.

Hands down, one of the best video recording apps

If you're into iPhone videographer even the slightest, this is an absolute necessary app. It's very stable, gives you more control than any other video recording app, and easy to use. The ability to set rack focus, zoom, exposure and color balance (and program them all to be controlled and changed at the same time) opens up for a ton of creativity that hasn't been done before on any other app. I definitely recommend it; Worth every penny.

File Transfer

I’ve just downloaded the app and shot a quick little scene just to check it out. I tried to export it to Luma Fusion for fx and noticed there’s no way to export the video unless you import via file sharing to a computer. It’s possible I’m missing something since I just purchased it but if there’s no way to share/move the videos besides a computer then this app was a poor choice for me. In this modern age most individuals want to move their files around without being restricted to a computer. This is the only major flaw for me and it’s likely I’ve wasted my money. If exporting video isn’t a problem for you then I’d highly recommend this application.

Hello and thanks for the feedback.

There is actually a way to share movie files other than through iTunes file sharing. In the film library you can swipe right on the large thumbnail to reveal the share and delete options. The share options allow you to copy to the camera roll or other apps or share via AirDrop.

We realize this option is a bit hidden and will be making it a little more obvious in a future update. Hope this helps.

My Fav Video Recording App

I’ve used many of the popular video apps, recommended because of its manual control or flat color profiles, but this app is my favorite. It’s slick, easy to use, the manual controls are intuitive. I can customize settings and use my anamorphic lens. Frame rates are excellent, they drop far less often than other apps. Shooting at 60fps is clean, no stuttering. The only thing I haven’t been able to figure out is how to get the record button on my osmo mobile 4 to work with this app. Otherwise, highly recommend this app.

Make it work with a Bluetooth remote or gimbal please, then I’ll give it 5 stars.
