Halumo: Photo Editor
Your professional darkroom
Free
39 photographer-designed looks, one-tap subject and sky selections that run on your iPhone, and an AI that turns a sentence into real, editable adjustments.
Halumo is a professional photo editor built natively for iPhone. It brings together a deep collection of nondestructive light and colour adjustments, one-tap AI selections that run entirely on your device, 39 photographer-designed looks, and an AI that turns a sentence into a full set of real, editable adjustments.
Everything you need to finish a photograph
• Edit with a complete collection of nondestructive adjustments — exposure, contrast, highlights, shadows, whites, blacks, temperature, and tint — and your original is never altered
• Shape contrast precisely with Tone Curves on RGB, Red, Green, and Blue
• Edit colour exactly with an eight-band Colour Mix, tuning the hue, saturation, and luminance of each band on its own
• Sharpen with radius and masking control, and reduce luminance and colour noise separately
• Add a vignette, correct chromatic aberration, and apply lens-distortion correction to RAW files
• Crop, straighten, rotate, and correct perspective
• Follow every change in a live Histogram
• Compare before and after with a split view, and step back through a compressed History and named Versions
Selections powered by AI
• Select the subject, the sky, or the background in a single tap
• Press and hold any object in the photograph to select just that object
• Add radial, linear, and brush masks, refine any selection by colour and luminance range, then invert, combine, and rename them freely
• Every AI selection lands as an ordinary mask, editable with the same tools as one you drew by hand
Describe the edit you want
• Say what you want in plain words and get a full set of real adjustments — every one visible, editable, and undoable like any other change
• Ask AI to adjust a mask you have already made, or to make a new selection for you
• Ask for one of Halumo's built-in looks by name and get the look itself
• Dial any result with Strength, ask for a Variation, or undo it outright
• Turn on Visual AI when you want the model to read the photograph
39 built-in looks
• Apply looks designed for everyday, film stock, cinematic, night, portrait, landscape, and black and white photography
• Preview any look on your own photo before you commit to it
Shoot, edit, and save
• Shoot with the built-in camera and open every frame for editing the moment you take it, with the original saved untouched in the background
• Save a full-resolution copy back to your library and reopen it later
• Share a JPEG anywhere
• Opens HEIC, JPEG, PNG, WebP, screenshots, and RAW files

SELECT THE SKY IN ONE TAP
Masks has a new Sky button. It selects the sky and gives you an ordinary mask — invert it, refine it, brush it, like any other.
SEND A PHOTO STRAIGHT TO HALUMO
Halumo is now in the share sheet. Share a picture from Safari, Files, Messages or anywhere else and it opens in Develop, without saving it to your library first.
19 NEW BUILT-IN LOOKS
The preset library grows to 39: everyday looks, film stocks, cinematic grades, night scenes, portraits, landscapes, and black and white.
FIXES AND IMPROVEMENTS
Deep skin tones hold their detail under the darker looks, and a saturated sky no longer flattens into a band of one colour.
