Lake: Coloring Book for Adults

What it does

Lake is a digital coloring book app focused on mindfulness and creative expression. It provides a vast library of hand-drawn illustrations from independent artists around the world. Beyond simple coloring, the app positions itself as a wellness tool, featuring a "Coloring Journal" that allows users to track their mood and generate custom color palettes based on their feelings.

Where it shines

Lake excels at creating a personal and human-centric experience. The onboarding is a prime example, using a detailed quiz and a clever, swipe-based art preference selector (00:56) to tailor the content. This makes the setup feel interactive rather than a chore. The integration of the Coloring Journal (08:28) is another high point, linking the creative act to emotional self-awareness in a way few apps do. Finally, the app's user interface for coloring is intuitive, with a helpful tutorial (02:01) and easy access to a variety of brushes and color wheels.

UX highlights

Gamified Onboarding: The "Would you color this?" swipe interaction (00:56) is a fun and effective way to gather user preferences.
Artist Attribution: Every piece of art prominently features the artist's name, reinforcing the app's commitment to its creative community (01:54).
Contextual Tutorials: Tool tutorials for coloring appear just-in-time when the user first enters the editor (02:01), ensuring the information is immediately relevant.
Multiple Brush Types: The editor offers a range of tools like paintbrush, spray can, and fill bucket, each with distinct textures and sounds (05:05), adding richness to the creative process.
ASMR Sound Design: The app includes optional ASMR sounds for different brushes, enhancing the relaxing and immersive quality of the coloring experience (07:47).
Intuitive Color Selection: The palette wheels and color picker are easy to navigate, allowing for quick selection and customization of hues (02:14).

Monetization & growth

The app uses a free trial model, presenting a paywall after the personalization quiz (01:22). The initial paywall clearly outlines a timeline for the 7-day trial, showing when reminders will be sent and when the charge will occur. A second screen (01:25) presents yearly and monthly options, highlighting the yearly plan as the default. The pricing is framed with a per-month breakdown to make the annual cost seem more accessible. The app also features a prominent rating prompt (08:06) after a user has engaged with the core coloring feature.

Who it’s for

Lake is designed for adults seeking a creative outlet for relaxation, mindfulness, and stress relief. Its target users are likely interested in art, self-care, and journaling. The emphasis on supporting independent artists also appeals to a user base that values creativity and community. The simple interface makes it accessible to beginners, while the variety of tools and artwork can satisfy more experienced digital artists.

Notes & opportunities

While the onboarding is thorough, its length might be a point of friction for some users eager to start coloring immediately. The initial tutorial pop-ups within the editor (02:01, 04:14), while helpful, could be consolidated into a single, skippable walkthrough. The app could also explore more ways to feature artist stories or collections on the main feed to further strengthen the community aspect that it champions so well.
