DELTAMin vs KBS CE

Creating a truly valuable product like DELTAMin requires a long-term commitment to understanding and addressing user needs. We remain focused on the real-world user experience, striving to refine our product capabilities so that technology and design genuinely serve users' daily requirements. DELTAMin is a user-oriented management application that organizes its features around the relationships between tools, tasks, and costs. Users can configure parameters—such as pricing, cycles, capabilities, and format constraints—and verify coverage. The app supports task management, usage timing, frequency tracking, and payment logging, while visualizing resource allocation and cost fluctuations through coverage matrices, bar charts, line graphs, and donut charts. A comparative analysis feature combines weighted set coverage, functional similarity, and constraint-based search to retain essential tools and identify functional gaps; a conditional analysis tool allows for the simulation of changes in pricing and demand. We believe that a great product is not created in a single step but evolves through continuous usage and feedback. User questions, suggestions, and real-world experiences are vital drivers of product improvement. We carefully analyze every piece of feedback and continuously iterate to ensure the product matures and improves over time.

KBS CE is an expense-tracking application centered on a weekly discretionary budget, presenting financial data through a clear, dashboard-style interface. The app features five distinct sections: "This Week," "Add Entry," "Transactions," "Weekly Report," and "Settings." It allows users to set and save a unique budget for each week, log expenses, income, and refunds, while automatically calculating net spending, remaining budget, and any overage in real time. Users can gain insights into their spending patterns through seven-day bar charts, categorical donut charts, and cumulative line graphs, with the ability to review historical weekly records at any time. Transaction entries can be searched, edited, deleted, or adjusted by date, and users have the flexibility to decide whether specific income items should increase their available budget. Additionally, the app supports data import and export, device authentication (security lock), and offline functionality—ensuring that weekly budgeting remains transparent and manageable, while balancing ease of daily use with the privacy of personal financial data.
