In today’s digital world, mobile work is a key part of office life. Cube Apps Limited supports this trend by offering curated Android and iOS apps that make communication and collaboration easier. Their apps, PDF Scanner and Faxium, focus on mobile faxing and online signing to streamline workflows and promote paperless offices.
As user needs evolve, demands for better document readability, editing, and security have grown. To enhance the user experience, Cube Apps Limited sought to integrate advanced PDF features and turned to ComPDFKit, a professional PDF solution provider.
What Challenges Have They Met?
1. Lack of Advanced PDF Features
Cube Apps Limited’s PDF Scanner app is designed to help users manage important documents anytime and anywhere using just a phone. However, as digital work continues to grow, users now want more advanced features like editing and adding notes to documents. Cube needs to add advanced PDF features to the app quickly to improve the user experience and keep more users.
2. Long-term Demand for A Reliable SDK
Both PDF Scanner and Faxium have large and growing user bases. Users may open many documents at once, so SDK stability is critical.
Because of this, Cube Apps Ltd has high standards for SDK reliability and wants to build a long-term partnership. This will help them improve app features, meet user needs, and stay competitive in the market.
3. Challenges of Self-development
In today’s fast-changing market, quickly meeting user needs is key to staying competitive. But developing advanced PDF features takes time and is complex. To upgrade their product and meet growing demands, choosing third-party technical support is a more efficient and reliable solution for Cube Apps Limited.
ComPDF Offers Customized PDF SDK Solution to Overcome The Challenges
1. ComPDFKit PDF SDK: Comprehensive Advanced PDF Features
ComPDFKit PDF SDK offers complete advanced PDF features like viewing, annotating, forms, signing, and security. During the cooperation process, ComPDF quickly responded to Cube Apps Limited’s needs for advanced PDF features and provided powerful, easy-to-integrate Android PDF SDK and iOS PDF SDK. This helped their products upgrade and improve quickly to meet user needs and boost user experience and satisfaction.
2. Customization: SDK Memory Optimization
To meet Cube’s strict SDK stability needs, ComPDF’s R&D team focused on memory optimization. We made sure the app does not use too much memory when opening documents many times, and can handle many documents open at once without crashing. The main improvements include:
- Optimizing the page pre-rendering process to avoid loading too much at once and reducing memory use by loading resources only when needed.
- Improving resource release by cleaning up caches, rendering data, and temporary objects quickly when closing documents to reduce memory pressure.
- Optimizing how document objects are created and released during frequent opens to prevent memory fragmentation from repeated creation.
3. Efficient Technical Support to Achieve Repeat Cooperation
Responsive technical support is always a core promise of ComPDF. In cooperation with Cube Apps Limited, the ComPDF R&D team quickly responded to the technical needs and solved problems to keep the project running smoothly.
In the first cooperation, the PDF Scanner app has enhanced its features in a short time with the help of ComPDFKit PDF SDK. Exciting, it received good user feedback, with a high market rating of 4.5, 144+ user reviews, and over 10,000 downloads.
Based on this success, Cube Apps Limited invited ComPDF for a second cooperation to build the Faxium app and add document compression features. Faxium launched smoothly in April 2025 and received positive user feedback within two months. This helped Cube Apps Limited grow its user base and stay strong in the market.
Future Cooperation Prospects
During the cooperation with Cube Apps Limited, ComPDF built a long-term partnership by providing powerful, advanced PDF features and responsive technical support. In the future, Cube Apps Limited and ComPDF are expected to work together to improve, optimize, and expand product features, respond quickly to market changes, and meet user needs. This will help improve user experience and keep market competitiveness.
