Development Achievements
English Visual Dictionary
We developed the English Visual Dictionary,a dictionary app that allows users to learn English in over 30 languages. We focused on UI/UX design to ensure ease of use for everyone. To facilitate English learning, the app includes features like bookmarking, offline learning, dark mode, and a powerful search function that also extracts related keywords.
We handled everything from planning and design to development and operation.
Yasai App
An app that connects producers and consumers, allowing users to purchase and pick up fresh produce directly from the farm.
Available on a variety of devices including iPhones, Android smartphones, tablets, and computers.
Link Mall
A platform that allows users to sell products simply by posting links. This simplifies selling products through social media and email. Even without a computer, users can register, manage, and send shipping notifications from their smartphones.
Developed in response to a local bakery owner's struggle to start an online shop.
Our Services
Development Flow
STEP.1
Estimate and Contract
We carefully gather your requirements, discussing the app's purpose, functionality, design, target users, and other aspects. Based on this, we propose the optimal development plan and estimate.
STEP.2
Design and Testing
Our app design process involves wireframing for screen layout, prototyping for usability testing, and finalization based on your feedback.
We ensure your satisfaction by sharing the design throughout the process.
STEP.3
Development
In the coding phase, we program the app's functionality based on the approved design.
We maintain transparent communication by providing regular updates on development progress.
STEP4
Confirmation and App Submission
After development, you'll review and test the app to ensure it meets your requirements in terms of functionality and design.
We then handle the app submission process to the App Store and Google Play, ensuring compliance with their guidelines for a smooth release.
STEP.5
Operation and Maintenance
We provide ongoing support for your app after release, including OS updates, security measures, and performance monitoring. We also offer continuous improvement suggestions based on usage analysis.

Finite Field K.K's Strengths
Flutter App Development
We primarily use Flutter for development. The biggest advantage of Flutter is the ability to develop both iOS and Android apps from a single codebase. This significantly reduces development time and cost.
Furthermore, the hot reload feature allows for real-time previewing of code changes, improving development efficiency.
Flutter also boasts beautiful UI and high performance.
In-House Engineers and Designers
Having in-house engineers and designers allows us to develop your app smoothly and with high quality. Because our team works together from development to design, communication costs are reduced, and we can respond quickly to your needs.
For example, development modifications due to design changes can be coordinated in-house immediately, minimizing rework and delays. Also, by directly sharing your requests with both engineers and designers, we can consider the best solutions from both perspectives and deliver a higher quality app.
By managing the entire development process internally, we maintain thorough quality control and deliver apps that meet your expectations.
Expertise in Multilingual Development
We have team members fluent in English, Chinese, and Tagalog. This allows us to conduct essential development processes like user interviews and testing in the user's native language, and develop apps that are sensitive to the cultural and market trends of those languages.
