Mosaic Letter: Photo Mosaics
Your album becomes one artwork
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Mosaic Letter builds one large mosaic artwork out of the photos already in your album.
From a distance it reads as a picture. Up close, every tile is an untouched photo of your own.
◎ No color is painted over your photos
Most mosaic apps tint each tile to match the target image. Mosaic Letter applies no color correction and no filters at all. Zoom in and nothing looks muddy — you see the shot exactly as you took it. Photos are never cropped into pieces either: each photo is used whole, as one tile.
◎ The same photo never clusters
Identical photos are kept a set number of cells apart. A slider lets you choose between "use as many different photos as possible" and "prioritize color accuracy", so you decide the trade-off yourself.
◎ See the outcome before you build
Mosaic Letter compares the colors of your selected photos against the target image and tells you what is missing before generating — for example, "not enough blues". You can add more photos right there, so there is no build-and-retry loop.
◎ Everything stays on your device
Mosaics are generated entirely on your iPhone. No account is required, and your photos are never uploaded anywhere.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
We improved the accuracy of the source photo check.
• The check now looks at how many photos can cover each color, not just whether a matching color exists. If a color is in short supply, you are told before generating — so the mosaic no longer repeats the same photo to fill a gap.
• Adding photos to a selected album now re-runs the check right away, so newly added photos are reflected immediately.
We welcome your feedback from the form in Settings.
