Brackt is the only iPhone and iPad app built exclusively for bracketed RAW to HDR merging. Import your exposure brackets, merge in seconds, and export professional HDR with full dynamic range. No cloud, no account, no cables.
Key Features
• HDR Merge: Combine 2-7 bracketed exposures into one high dynamic range image
• Two Merge Modes: Standard fusion is fast and forgiving. Great for handheld brackets and tricky scenes. Radiometric mode reconstructs true scene radiance for superior pixel-level detail on precise, well-balanced brackets.
• 10 Tone Mapping Algorithms: Reinhard, ACES Filmic, Hable Filmic, Drago, Durand, Ward Local Adaptation, Photographic, Exposure, Exponential, and HLG. Switch styles on the result screen without re-merging. Thumbnails preview each look in real time.
• Advanced Deghosting: 4 sensitivity levels (None, Low, Medium, High) for clean results even with moving subjects, flowing water, or wind-blown foliage
• Auto Alignment: Corrects camera movement between exposures. Works with handheld brackets and imperfect tripod shots.
• Lens Correction: Automatically corrects lens distortion as your RAW frames are decoded, so straight lines stay straight across the merge.
• In-App Photo Editor: Adjust tone, color, and clarity. Apply presets. All without leaving Brackt.
• Export Manager: Choose format (HEIC, 16-bit TIFF, JPEG, PNG), resize, and add borders before saving.
• Full RAW Support: DNG, CR3, NEF, ARW, RAF and large JPEGs. Extensive camera brand coverage including DJI Mavic and other drone RAW files.
• 16-bit TIFF Export: Take your HDR straight into Lightroom, Capture One, or Photoshop
• HEIC Export: Real HDR on Apple displays using the ST.2084 PQ transfer curve
• Share Extension: Send brackets to Brackt directly from the Photos app or Files app
• 100% On Device: Private, fast, and works everywhere. No internet needed.
• 30 Languages: Brackt follows your device language automatically, including Chinese, Japanese, Korean, German, French, Spanish, Turkish, and many more.

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!
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.
Developer Response
Sorry to see you go — version 1.2.0 resolves the Canon and crash bugs you mentioned.Feedback like yours helped us move fast, so we genuinely appreciate the time you spent testing the app.
Cartoonishly failed

Ghosting and failed overlay make the finished file completely useless. Tried the three samples and all three looked like a bad AI filter of a triple exposed image.
