Big Grid turns a collection of personal photos into one large collage or color-matched mosaic. Choose from square, landscape, or portrait frames, then set a grid as large as 55 by 55 cells. For a mosaic, select a target image and let the app use the colors in chosen photos to recreate its overall shape. Albums can be selected in order, and each cell can be adjusted so a face or important subject remains visible. Finished projects can be saved to the photo library or exported as a PDF or image file for sharing or printing. The developer says processing stays on-device and photos do not leave the phone; an account is not required. Big Grid is free to use according to the listing, though users should verify export dimensions and printer settings for a particular project.
