About Polygon – Art Coloring Book
I downloaded Polygon – Art Coloring Book on a whim, looking for something to do with my hands during my evening commute that wasn’t just scrolling social media. I’ve tried a few coloring apps before, but this one from Severex immediately stood out because of its distinct geometric art style. It’s not your typical kids’ coloring book; the designs are all built from interlocking polygons, which gives everything a cool, modern stained-glass or low-poly 3D model look. After using it for a couple of weeks, I can say it’s become my go-to app for a quick 10-minute mental reset.
Features & Highlights
The core library is impressive for a free app. I’ve counted well over a hundred designs, sorted into categories like Animals, Patterns, Mandalas, and Fantasy. The wolf and owl designs are my personal favorites. The coloring tools are straightforward: a color picker, a fill bucket, and a brush. I really appreciate the “smart fill” feature—if you tap a polygon, it fills just that shape perfectly without bleeding over the lines, which is essential for these intricate designs. You can zoom in super close for detailed work on tiny triangles. I also like that you can adjust the brush size for bordering, and there’s an undo button that feels unlimited, which saved me more than once when I mis-tapped.
User Experience
Opening the app is simple. You’re greeted by the gallery of designs, and tapping one loads it immediately. I remember the first time I finished a complex peacock design; watching the last segment fill in and the whole image snap into a vibrant piece was oddly satisfying. The interface stays out of the way. My only gripe here is that saving and sharing my artwork felt a bit hidden—I had to poke around the top corner menu to find the export option. Once I found it, sharing my colored wolf to my friends was easy, and they actually asked what app I used. The app runs smoothly on my mid-range Android phone with no lag, even when zooming.
Pricing
The app is completely free to download and use. The entire catalog of base images and all the core tools are unlocked. Monetization comes through optional rewarded video ads to unlock special color palettes or certain premium design packs, and there are occasional banner ads at the bottom of the screen. I watched a few 30-second ads to get a metallic color pack, and it felt like a fair trade. There’s no aggressive push for subscriptions or large upfront purchases. For a free app, the value is outstanding. You get a full, functional, and enjoyable experience without spending a cent.
Updates & Support
Looking at the update history on the Google Play Store, the developer Severex pushes out updates every month or two. Recent updates have added new design packs (I saw a “Mythical Creatures” pack added last month) and minor bug fixes. I haven’t needed to contact support directly, as I haven’t encountered any crashes or major issues. The app description has an email for feedback, which suggests they’re open to it. The consistent addition of new content shows they’re actively maintaining it, which is a good sign for an app I plan to keep installed.
Security & Privacy
I downloaded Polygon from the official Google Play Store. The app’s Play Store listing shows a very minimal data safety section. It states the app may collect coarse location data and device IDs for third-party advertising purposes. In my use, I haven’t been asked for any sensitive permissions like contacts or files. The ads are standard mobile banners and video ads from networks like AdMob. If you’re privacy-conscious, it’s good to know there is ad-related data collection. You can limit ad tracking through your device settings, but the app itself doesn’t have a built-in privacy toggle.
How does the smart fill feature work in Polygon – Art Coloring Book?
The smart fill tool lets you tap a single polygon, and it fills only that shape perfectly without bleeding into adjacent areas. This is essential for the app's intricate geometric designs, and you can zoom in close to work on tiny triangles without worry.
Can I undo a mistake if I accidentally fill the wrong polygon?
Yes, the app includes an undo button that feels unlimited, so you can reverse any mis-tap or unwanted fill. This saved me several times when I accidentally colored the wrong section of a complex design.
I can't find the save or share option—where is it located?
The export option is a bit hidden in the top corner menu of the interface. Once you tap that menu, you can save your finished artwork to your device or share it directly with friends.
Why does the app sometimes lag or crash on my mid-range Android phone?
The app runs smoothly on most mid-range devices, but if you experience lag, try closing other background apps or restarting your phone. If crashes persist, ensure you have the latest version installed from the app store.
How does Polygon compare to other coloring apps like Color by Number?
Unlike typical coloring apps that use numbered sections, Polygon focuses on a modern, low-poly geometric art style with interlocking shapes. It offers a more creative, freeform experience with smart fill and brush tools, making it feel less like a paint-by-numbers game and more like a digital art project.
