Read full description

Nōtan is a Japanese design concept involving the play and placement of light and dark elements next to the other in the composition of art and imagery. The Yin Yang symbol is an example of this design philosophy. The use of Nōtan in art composition is a powerful tool to help the artist identify the structure of the light and dark portions of the image they want to incorporate into their project. The first function simply divides the image into black and white with colors above the set value being white and those below being black. You can then use the slider to move that line to enhance detail that may otherwise be obscured. The second and third functions displays the image in either a grayscale or color so the artist can focus on the structure and design of the image. The next 3 functions are Levels. They set either 3, 4, or up to 10 levels of color spread over black, gray and white pallets. The 3 and 4 levels have sliders to adjust where those levels are while the Levels function just evenly divides the image by the number of levels. Finally the last function is Slice. It allows you to select a small range of values and highlight those in black and everything else white. And as of version 3.1 you can now invert the display of each of the filters. Lighter values have been displayed in white, but now you can invert them to see those in black which can really help bring out detail. And of course, share your image in many ways. Any artist will benefit from seeing their work in a different light. NotanIzer is that light.

Verdict

The call

The clearest difference is price: Brushstroke at Free against NotanIzer's $1.99. Brushstroke also leads on rating (4.8 vs 4.3) and ratings volume (14K vs 105). NotanIzer's advantage is in-app purchases (none vs 10) and chart position (#38 vs unranked). On review sentiment, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Brushstroke holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Brushstroke has 14K ratings behind it against 105, so its average is the more settled of the two. Written reviews complicate that: 80% of Brushstroke's written reviews are positive against 82% of NotanIzer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Brushstroke ships an update monthly, NotanIzer every 2 months. The most recent releases landed on November 4, 2026 and November 6, 2026 respectively.
