Aspects of present disclosure relates to a mobile geotagging device, a mobile geotagging system, and methods of mobile geotagging system. In certain embodiments, mobile geotagging device includes: a display screen, a processor, and a non-volatile storage device storing a mobile geotagging application. When executed by processor, mobile geotagging application causes the processor to: generate a time-coded image containing an initial starting point of time, track timing and geolocation information of mobile geotagging device while a digital camera is in use, and store tracked timing and geolocation data, receive a set of images and videos from digital camera, append timing and geolocation information in EXIF into corresponding image files and video files based on a timing difference between digital camera and mobile geotagging device and tracked timing and geolocation information data stored in geolocation/timing tracking storage, and store the images and videos having updated timing and geolocation information in image/video storage.
