Idol Draw: Coloring Master

Idol Draw: Coloring Master, from JUMBO GAMES Studio, is a colouring app designed to be soothing rather than competitive. It pairs simple line art of idol-style characters and monsters with gentle ASMR sound effects, aiming for a calm, low-pressure pastime.

Each session means picking a character drawn with clean outlines and filling it in with your own colour choices. The app encourages tracing the lines and adding colour stroke by stroke while soft sound effects play in the background. The description mentions hundreds of characters to work through, and finished art can be shared. There are no timers, scores or failure states described; the appeal is simply watching a blank figure turn into a finished, colourful picture at your own pace. That makes it more of a relaxation tool than a game in the usual sense.

The record shows a 3.8 average from 2,740 ratings, which is a mixed picture: 57% are five-star but 18% are one-star. Despite the modest rating count, installs have reached 10,000,000+. It has no in-app purchases and relies on ads for funding. The update on 2026-09-22 is very recent, Android 9 or later is required, and it is rated for all ages. We list 19 versions, the latest being 0.21 at 187.9 MB.

People who want a quiet, screen-based wind-down with no spending pressure may like it. Those bothered by ads or hoping for detailed drawing tools should look at a fuller art app instead.
