Brackt — RAW to HDR Merge for iPhone & iPad
For the first time on iPhone, Brackt brings true bracketed RAW to HDR merging — designed for photographers who want desktop-grade dynamic range and color accuracy. Brackt merges your bracketed or RAW photos into professional, high-resolution HDR images with advanced tone mapping and deghosting.
Merge multiple exposures to capture the full dynamic range of your scene — preserving shadow detail, highlight recovery, and natural color balance. Whether you shoot RAW or high-quality JPEG, Brackt processes your files intelligently to produce crisp, balanced images without ghosting artifacts.
Key Features
• HDR Merge – Combine multiple bracketed shots into a single high-dynamic-range image.
• Advanced Deghosting – Intelligent motion artifact removal with four adjustable sensitivity levels.
• Professional Tone Mapping – Reinhard algorithm for natural contrast and accurate color reproduction.
• RAW & High-Resolution Support – Import RAW files (DNG, CR3, NEF, ARW, RAF) or large JPEGs.
• Flexible Export Options – Save HDR results as 16-bit TIFF for pro workflows or HEIC for efficient sharing.
• On-Device Processing – Fast, private HDR merging powered by CoreGraphics — no internet required.
Why Brackt
HDR photography demands precision. Brackt is built for photographers who use exposure bracketing or RAW shooting to capture every tonal detail. Instead of losing skies to overexposure or shadows to crushed blacks, Brackt balances your scene naturally — exactly as you saw it.
Mobile-First by Design
Brackt is created exclusively for iPhone and iPad to deliver fast, precise HDR merging right where you shoot. It’s a mobile-first experience built for today’s workflow — optimized for touch, powered by the device’s processor, and never dependent on desktop software.

So this app is about as close to a merge-to-HDR solution for exposure bracketing as I've seen anything come so far, at least as far as iOS apps are concerned.However it's a little disappointing that it won't detect RAW format images in the Photo Library and will save as JPG. You have to move them to the Files app for it to recognize a DNG and merge to a TIFF.It should allow you to choose between JPG or DNG (if available) for images in the Photo Library, as well as allow you to choose your output file format. If the dev can add those two things, easy 5 star.I'll be sure to update my review if that change is made.
Developer Response
Thank you so much for your detailed review and suggestions! We’re thrilled you’re finding the app useful for HDR bracketing. You’re absolutely right about RAW/DNG support with Photo Library and output format options—we agree those are must-have features.We’ll be working on fixing that immediately so you can import directly from the Photo Library and choose your preferred file format. Your feedback really helps us improve quickly. Hopefully we’ll earn that 5⭐ from you very soon!
So Much Potential! Stopped Working After Purchasing
KPW1994
I found Brackt last week and was immediately impressed. The first couple of images I created during the free trial were genuinely great—full resolution, sharp, and visually impressive. It actually surprised me how good the results were right out of the gate.Because of that, I didn’t hesitate to purchase the lifetime license for $90. That’s not exactly impulse-buy territory for most apps, but the early results made it feel justified.Unfortunately, everything fell apart after upgrading.Once I unlocked the full version, the app started exporting images at a very low resolution (around 960x360), making them basically unusable compared to the high-quality outputs I got during the trial. That alone completely undermines the value of the app. It also completely fails to import RAW files, which is a pretty major limitation for anyone even remotely serious about photo editing. On top of that, there’s a noticeable licensing glitch where the app briefly thinks I’m still on the trial every time I open it before correcting itself. Not a dealbreaker on its own, but it doesn’t inspire confidence.I reached out to the developer with a detailed email explaining the issue and didn’t receive any response after a full week. That’s the part that stings the most. Bugs happen, especially with newer apps, but silence after a paid purchase is hard to overlook.This app clearly has a lot of potential. The results I saw during the trial prove that. But right now, the post-purchase experience feels broken, and the low-resolution exports and lack of RAW support make it unusable in its current state.I really hope the developer addresses these issues soon, because I’d genuinely like to keep using it. As it stands, though, it’s hard to recommend until the core functionality is fixed and support improves.
Not usable with Canon camera
Nicky Leo
Probably the only solution for RAW exposure bracketing on iOS. I was expecting high, yet the result is basically not usable. Combining multiple CR3 RAW photos does not preserve bright areas at all, even with quality priority selected. Not sure if those underexposed ones were indeed processed. Moreover, the "bracketing" also creates mysterious purple hues around all items captured in my photo. On the other hand, combining multiple Canon JPGs will simply crash the app again and again. Wish I could have a refund.
