digiKam is not available for iPhone but there are some alternatives with similar functionality. The best iPhone alternative is Adobe Lightroom. It's not free, so if you're looking for a free alternative, you could try Piwigo or Apple Photos. If that doesn't suit you, our users have ranked more than 50 alternatives to digiKam and ten of them are available for iPhone so hopefully you can find a suitable replacement. Other interesting iPhone alternatives to digiKam are ACDSee Photo Studio (Paid), Slidebox (Freemium), Darkr (Free) and Mylio (Freemium).
ACDSee is a complex, multi-purpose application that serves for viewing, organizing and editing digital photos. Furthermore, images can be shared on social websites or your own space on the developer’s website.
Organize your gallery photos with quick gestures! Scroll through your photos in fullscreen and swipe up to delete unwanted photos or pick an album to sort into. Compare similar/duplicate photos and quickly and delete them with a swipe. It’s that easy.
Make your best shots even better with RAW Power™. RAW Power unlocks the hidden power of Apple's RAW engine with simple, easy-to-use controls. Use it as an editing extension inside Apple Photos, or as a standalone, non-destructive RAW photo editor with file browser.
Priime offers filters as a way for mobile photographers to apply looks to their images with a tap of the finger. The app goes beyond apps like Instagram, however, with features such as filter suggestions and a filter marketplace.
