Needs

The application had entered the market quickly and established an audience, but its initial implementation made further development harder to maintain.

The next stage required more than a visual refresh. The product needed a stronger technical foundation, more capable editing tools, and coordinated behavior across the mobile interface, backend processing, and monetization services.
CHALLENGES

The Key Challenges We Addressed

01

Modernizing an Existing Product in Stages

The original codebase needed substantial improvement while the application continued to evolve. We progressively refactored and rewrote individual parts of the application alongside feature development. This approach allowed technical improvements to move forward with the product roadmap and supported the broader version 2.0 redesign.

02

Connecting Mobile Editing With Backend AI Processing

AI editing required several coordinated steps: capturing user input, preparing image data, sending it for processing, and displaying the returned result. We integrated these steps into the mobile editing flow and connected the application to a backend working with multiple AI models. This kept complex processing behind a familiar interface while allowing the backend to support different processing options.

03

Aligning AI Usage With Subscriptions and Credits

Access to AI features depended on more than subscription status. Free users had limited usage, premium users received higher allowances, and additional credits provided access after those allowances were exhausted. We connected the mobile application, backend quotas, and payment integrations to support these access rules throughout the editing journey.

04

Supporting International Product Variations

International expansion introduced requirements beyond translation. Interface content, feature availability, and purchase screens needed to accommodate different audiences. We extended localization support and implemented regional configuration capabilities, giving the product team more flexibility to adapt the experience for individual markets.
SOLUTION DEVELOPMENT

A Unified Experience for Photo Editing, AI Tools, and

Flexible Access

Redesigned Native Interface

We implemented the version 2.0 interface using SwiftUI alongside UIKit where needed. The work combined updated screens and interactions with improvements to the underlying implementation, supporting a more coherent editing experience and continued feature development.

AI-Powered Editing Tools

We integrated object removal, image enhancement, and skin retouching into the application. Users can select an area or apply an enhancement, send the image for backend processing, and continue working with the returned result within the editor.

Subscription and Credit-Based Access

The application combines free usage allowances, expanded premium access, and additional credit purchases. We connected payment services with backend usage rules so AI access could reflect both the user’s plan and remaining allowance.

Expanded Collage Editing

We are extending the collage experience with flexible grids, photo positioning, zoom, and customizable aspect ratios. The updated workflow brings composition controls and photo adjustments together, helping users prepare images for different social content formats.

Product Analytics and Reusable Components

We integrated analytics across key interactions to help the product team understand feature usage and identify points of friction. Shared functionality is maintained in reusable libraries, allowing common components to support multiple applications without duplicating their implementation.

Localization and Regional Configuration

We extended localization to additional languages and adapted interface elements for translated content. Regional configuration supports variations in feature availability, while localized purchase screens allow offers and supporting visuals to evolve for different audiences.

RESULTS

ACHIEVED

RESULTS

20% Faster Delivery of Comparable Updates

Progressive refactoring and reusable components reduced implementation effort for recurring interface and integration tasks, helping the team deliver comparable updates in approximately 20% less development time.

25% Fewer Recurring Defects in Reworked Modules

Improvements to legacy code and clearer component responsibilities helped reduce recurring defects in modernized areas by approximately 25% compared with the period before those areas were reworked.

3 AI Tools Connected to Monetization

Object removal, image enhancement, and skin retouching were integrated with usage allowances, premium subscriptions, and additional credits, connecting advanced editing capabilities with multiple purchase options.

A Released Version 2.0 Redesign

The application received a refreshed interface supported by improvements to its existing codebase, bringing visual modernization and technical development into the same delivery process.
