Development of the Android application "Color by Number / Paint by Number" (MVP)
A mobile application needs to be developed for Android in the Color by Number genre (coloring by numbers), similar to popular apps on Google Play (Pixel Art Coloring, Tap Color, ColorAura, etc.).
At the first stage, an MVP version with basic functionality is planned, without a bonus system, ratings, and daily discoveries of paintings.
A catalog of coloring pages with predefined colors and areas will be provided from our side via API.
The developer does not need to create content or algorithms for generating paintings — only correctly implement the display and interaction with the ready data.
⸻
Main functionality (MVP)
1. Gallery of paintings
• Categories (for example: animals, flowers, landscapes, abstraction, etc.)
• Display of paintings in a grid format
• Ability to add new paintings in the future
2. Coloring mode
• Coloring by numbers
• Zoom and pan across the image
• Automatic filling of the area upon clicking
• Highlighting the active number
• Saving already colored areas
3. User progress
• Saving the progress of each picture
• Completion percentage
• Ability to continue coloring from where the user left off
4. Finished works
• Section "Completed pictures"
• Viewing finished works
• Saving to the device or sharing (optional)
⸻
Mandatory additional functionality
• When selecting a color:
• ✅ only the areas corresponding to the selected number are highlighted
• ❌ other areas cannot be colored (blocked from interaction)
⸻
Functionality that is NOT needed at the first stage
• ❌ Daily bonuses
• ❌ Daily discovery of paintings
• ❌ Ratings, leaderboards
• ❌ In-game currency, purchases with bonuses
• ❌ Social mechanics
(may be added in subsequent stages)
⸻
Technical requirements
• Platform: Android
• Support for various screen sizes
• Optimized performance with large images
• Preparation for publication on Google Play
⸻
Expectations from the performer
• Experience in developing Android applications
• Preferably — experience with graphics or game mechanics
• Assessment of timelines and costs for MVP
• Willingness for further cooperation (updates, new features)

I will do it perfectly without any problems. I have already worked on similar projects, it takes from 2.5 to 4 weeks depending on the API, design, and exact functionality of the first version. You won't find anyone better than me in terms of price and quality.

Your task in developing the Android application "Color by Number / Paint by Number" requires a confident approach to creating an MVP. I propose the development of a cross-platform application using Flutter, which will provide flexibility for future feature expansion.
I have been specializing in mobile application development for over 5 years, can integrate the necessary APIs, and create an intuitive user interface. My rate is $15/hour.
I am ready to discuss the details and your requirements.

323 Hello,
We have experience in developing Android applications with custom graphics, interactive mechanics, and optimization for working with large images. Your MVP for Color by Number is clear and technically well-formulated.
What we can implement:
— Gallery with categories + dynamic loading of pictures via API
— Coloring mode with zoom, panning, and auto-fill areas
— Highlighting the active number + blocking other areas
— Saving progress locally (or via backend if needed)
… — Completion percentage
— Section for completed works + export/sharing
— Optimization for large SVG/raster images
— Preparation for Google Play
For an accurate estimate, we need to clarify:
1. In what format are the areas provided — SVG, JSON masks, raster + coordinates?
2. Is offline functionality needed after the first download?
3. Is there a UI design, or do we need to develop it on our side?
Approximately, an MVP of this level would take 6–10 weeks of development.
We work at $30/hour. After technical clarification, we will provide a detailed budget range.
We are ready to enter into a long-term collaboration and scale the product to the next stages.
