Grid Spacer is a free iPhone application developed by Thomas Lojko in the Multimedia category, specifically under Graphic & Design. This program allows users to precisely adjust spacing in photos to create a harmonious grid layout. Users can select images from their photo library, apply filters, crop, resize, and fine-tune spacing using a slider. Additionally, users can preview their photos on a grid mockup and choose from various background colors. After editing, users can save the final image to their Photo Library with ease.

Grid Spacer provides a user-friendly interface for editing photos and creating visually appealing grid layouts, making it a handy tool for those looking to enhance their images for social media or personal projects.
