The photo-to-sketch app that stands out from the rest! SketchMee analyses, interprets and redraws your photo from scratch, instead of the simple edge filtering other apps do. New York Times sums it up: "This app turns your photos into pencil sketches of remarkable quality." Long time feature under "Staff Favorites / Impress Your Friends" in the US App Store. Just pick an image from your photo library, and watch it being sketched into a beautiful piece of art. Have endless fun playing around with settings, exploring a vast world of art possibilities. Extremely easy to use. A handful of simple but powerful controls make you the artist in charge, enabling a wide range of different sketch art styles. Unparalleled art quality. Not even desktop computer programs come close. Save your creations in 4K resolution. Zoom as deep as you like into the finished sketches to inspect the strokes. Your art will appear perfectly sharp at any zoom level. This is because sketches are built using vector curves, not from blocky pixel data.

Verdict

The call

The clearest difference is price: TwinViewer at Free against SketchMee's $4.99. TwinViewer also leads on update cadence (every 5 weeks vs every 4 months). SketchMee's advantage is in-app purchases (none vs 1) and rating (4.5 vs 4.0). On ads, device support and iOS requirement there is nothing between them.
