Macro & focus stacking · iPhone and iPad
Every drop
in focus.
Up close, only a thin slice of the subject is sharp. Sharp shoots or imports a focus series and merges it into one photo that is sharp from front to back, right on your iPhone or iPad.
Free to download. Sharp Pro from $3.99 a month, or $49.99 once.
Try it: drag the focus ruler to step through the frames, move over the photo to aim the loupe, then stack.
What it does
From the first frame to a 16-bit file.
Shoot a focus series with the built-in camera or bring one from your mirrorless camera. Sharp aligns it, blends it and renders a single all-in-focus photo.
Capture
A focus bracketing camera
Set the near point A and the far point B. Sharp picks the closest-focusing lens, counts the frames and steps the focus for you.
Capture
Peaking, loupe and grid
See exactly what is sharp before you shoot. Sharp waits until the phone is steady before each frame. HEIF or Apple ProRAW.
Capture
Coverage check
A chart of how sharp each frame is. Blurry frames and gaps are flagged while you are still at the scene.
Import
Bring your own series
JPEG, HEIF, PNG, TIFF and camera RAW from Photos or Files. Sharp splits a whole shoot into separate focus series.
Stack
Four stacking methods
Depth Map, Pyramid, Average and Wavelets, with a live preview that grows frame by frame. Tripod or hand-held alignment.
Stack
Sharpness and depth maps

Finish
Compare results
Put two methods side by side, drag a split slider or flicker between them, and keep the best one.

Questions
Good to know.
What is focus stacking?
Up close, only a thin slice of the subject is in focus. Focus stacking takes several photos of the same scene, each focused at a different distance, and merges their sharp parts into one photo that is sharp from front to back.
Which devices are supported?
iPhone and iPad with iOS / iPadOS 17.6 or later and an A13 Bionic chip or newer (iPhone 11 and later). Large high-megapixel RAW stacks work best with 8 GB of memory or more: iPhone 15 Pro and later, iPad with M1 or later.
How many frames do I need?
A flower or a coin may need 5–15 frames; insects, jewelry and minerals often need 20–60 or more. In Capture, Auto suggests a count, and the Coverage Check after shooting flags gaps and blurry frames.
Which method should I use?
- Pyramid: fine detail and overlapping edges such as hairs and bristles.
- Average: the cleanest result with the least noise, softer at edges.
- Depth Map: smooth surfaces and clean edges. Sharp Pro.
- Wavelets: like Pyramid, steadier where frames differ slightly. Sharp Pro.
Can I use photos from my camera?
Yes. Import a focus-bracketed series from Photos or Files: JPEG, HEIF, PNG, TIFF or camera RAW. Sharp splits a shoot into separate series automatically.
I went over a free limit. Can I still get a photo?
Yes. The Sharp Pro screen offers a second button, such as Render 15 frames, Render with Pyramid or Export JPEG, that finishes the job within the free limits.
How do I restore my purchase on a new device?
Sign in with the same Apple Account, open Library → Get Sharp Pro and tap Restore Purchases.
Where are my projects stored?
Only inside the app on your device. They are not included in iCloud or device backups, and deleting the app deletes them. Export the results you want to keep.

Stay sharp.
