Adobe Lightroom is a powerful photo-editing app for mobile that retains many of the features from its desktop counterparts, Lightroom, which earned a three-and-a-half star rating, and Lightroom Classic, a five-star Editors' Choice winner. Some of its standout tools include raw camera file profiles, noise reduction, profile-based lens corrections, and advanced color and lighting sliders.
