Smart-Grid
Just pick your photos – Gridium finds the right template for how many you chose. With its own story variant, or roll the dice for a surprise.
Gridium turns your photos into a collage in seconds – with 43 templates or freestyle on the new blank canvas. For iPhone, iPhone Duo and iPad.


New in 1.4
The blank canvas is an empty square or 9:16 story canvas. Add a photo as the background, put photos into shapes like a circle, heart or Polaroid, and place text and stickers wherever you like.



Square, circle, heart, star, arch, hexagon, diamond and more – insert, add a photo, done.
Polaroid stack, circle trio, film strip, focus and heart duo – in a single tap.
Original, vivid, warm, cool, B&W, noir, sepia, faded and dramatic – with live thumbnails.
Brightness, contrast, saturation and opacity, all continuous. Preview and export look the same.
Frames in any color – even, following the shape, or Polaroid-style with a wide bottom edge.
Your own photo fills the canvas and blurs smoothly – behind any template, too.
Coming in version 1.4.1
Closed, open or half-folded: Gridium follows the fold – nothing important disappears into the crease.



Open like a book: your collage sits left of the fold, the tools to the right. Templates, gallery and settings split exactly in the middle. Half-folded and standing up: your collage fills the top half and the tools sit below – where the device rests steadily on the table. Closed: everything fits the outer display, with navigation and tools neatly at the side.
The template overview uses an even number of columns, and cards and columns end right at the fold – no photo and no text sits in the crease.
Gridium already splits at the fold when the device lies flat. When you fold it, everything stays where it is.
Just as Apple intends: navigation and tools sit along the edge, with Back or Close always at the top.
