Lake vs PixelZen

Lake is a freemium iOS coloring app built around hand-drawn books from independent illustrators. The homepage advertises more than 1,500 unique illustrations and says additional books are coming. Tools include artistic brushes, palettes, a color picker and a rainbow with over 700 shades. Coloring is freeform, works offline and can include imported images. Lake presents coloring as a way to support mindfulness, relieve anxiety and unwind, while saying part of each subscription fee goes directly to artists. The app is intended for iPhone and iPad and is available in English plus 10 other languages. Lake began in 2016 with an idea for illustrators and fans to co-create. The App Store lists it as free with in-app purchases and a free trial. Listed options are Lake Coloring at $9.99 a month or $39.99 a year, and Lake Premium at $29.99, paid once, with no term specified. Apple’s listing says the developer may collect purchases, coarse location, identifiers, product interaction and crash data not linked to the user.

PixelZen is an iOS color-by-number app built around pixel-art canvases. Its numbered coloring mode rejects incorrect-color taps instead of leaving them in place. Pix’s Workshop turns a typed prompt or uploaded photo into a numbered pixel canvas, using one to three orbs per generation according to difficulty. The app includes themed collections of hand-picked canvases; new books arrive regularly, most are free, and some unlock with gems. A shared daily canvas provides a bonus reward and a separate streak, while login streaks can survive missed days. Hint, Bucket, Bomb, and Prism each provide one free charge daily. Premium adds unlimited power tools and Instant Finish. Completed canvases replay the coloring journey and can be saved or shared as high-resolution art. Guests can play without accounts, or sign in with Apple, Google, or email to keep progress across devices. Internet access is required, with no offline mode. The free plan costs nothing; Premium costs $9.99 a month.
