Focos brings DSLR-like photography to your dual-camera iPhone with large aperture and real bokeh effect, which most photographers have always desired.

DPReview, "Created by the same indie developer behind the apps Colorburn and MaxCurve, Focos takes your iPhone 7 Plus, 8 Plus or X's Portrait Mode shots and makes them look more professional by adding more realistic and customizable bokeh effects. The results should ostensibly look better than what Apple is generating with its own Camera app, but at the very least they'll be more customizable so you can find a more appropriate effect for every photo."

As a beginner having no prior photo shooting experience, you can take professional-grade pictures with this app at a go without expert skills.
As a professional, you'll be amazed at professional options available in this offer for you to simulate any type of lens including the top-level or defective ones.

- Press shutter to take pictures with the depth of field without painting or making selection.
- True 3D imaging.
- Large aperture and real bokeh like in DSLR with expensive lens.
- Import existing portrait photos and edit the bokeh effect again.
- Tap to focus after shooting.
- Various diaphragms generate different bokeh spot effects.
- Professional options simulate the pro lens such as creamy, bilinear, swirly, reflex and so on.
- View the portrait photos in 3D mode and add the depth filters intuitively.
- Simulate rainy, snowy or foggy weather with depth filters.
- Video tutorials and easy to use.
- Essential tool for iPhone 7 Plus, iPhone 8 Plus and iPhone X having dual cameras.

It is strongly recommended to download this app for those devices with dual cameras.
All sample photos in screenshots and trailers were taken by iPhone 7 Plus.

What's New in Version 1.1

New radial option simulates the distortion effect of some lenses. You can use some aperture options to make the famous Olympus Zuiko lens in Focos. These are the settings that needs to be used: 70% radial, -50% corrosion and 80% bilinear.
New reflex options simulates the ring bokeh of the reflex lens.
New continuous shooting mode lets you to take several original pictures without interruption, and you can edit them later.
The processed pictures will be saved into the specified "Focos" album.
To delete pictures, press and hold the thumbnails.
Reduces the computational complexity, increases the saving speed, and reduces the temperature when taking pictures.
You can replace the yellow cute icon with the professionally designed main icon from settings.
New diaphragm shapes have been added.
The aperture value shows f/16 ~ f/1.4 when adjusting it.
Aperture to defaults can be quickly restored.
New structure and motion blur filters added.
The App crashing when using multiple filters has been fixed.

In the next version, “Lens Presets” into Focos will be added. You will no longer be needed to use the complicated aperture options but will be able to directly tap the presets and quickly switch between different lenses. I will work with experienced lens experts to modulate the optical effects of various unique lenses and if you have a very in-depth study of lenses you can contact me for a paid consultation. support @ focos . me

Customer Reviews

Awesome...but instructions?

This app is amazing & unique in its ability to set a realistic and changeable depth of focus with specific bokeh fx as well as “special” novelty fx, in addition to lots of other variables that can be tweaked in different ways. I just have no clue what I am doing, especially as I make adjustments in the “effect” screen to “back bokeh” & “front bokeh” in a changeable 3-D image of my photo with perspective/angle that varies by degrees (?). I think it defaulted at 72 degrees? I have a 2 hour free trial of the pro-version, but unfortunately it will take me at least that long to experiment with the options. I wish the tutorials were explained better, because the action is too quick for me to understand what is happening, or what has changed. I will search online for tutorials that also explain each step as it is done. I can’t wait to learn how to effectively use all the options!!!

Amazing; hope for more features

Amazing being able to re-focus after shooting!

Would like to be able to export larger files with less compression.

Very responsive developer!


I’m not easily blown away but this app makes the dual camera system work like nothing I’ve seen! Instant lifetime purchase without hesitation!
