Formula Lab - Calc & Simulator

For those who demand more than just a simple calculation.
Formula Lab is a next-generation simulation tool that lets you build your own calculation models and instantly visualize complex "what-if" scenarios with countless variables.

◆ Start in One Tap with Templates
Includes a rich library of practical, professional templates like "Compound Interest," "Game Damage (Crit Avg.)," "Loan Payments," and "Physics Formulas." Complex equations become yours with a single selection. No need to start from scratch.

◆ Build & Grow Your Calculator at Your Fingertips
Freely create and edit your own unique formulas in a powerful editor that supports functions like max(0, {ATK} - {DEF}), min(), and floor(). Parameters can be written simply as {Variable Name}.

◆ Switch Scenarios Instantly with Presets
Save combinations of parameter values as named Presets like "Warrior Lv10" or "Bear Market Scenario." Instantly switch between situations from a dropdown menu to compare how results change.

◆ Discover the Optimal Solution with Dynamic Graphs
Simply choose a parameter for the X-axis to see how results change on a beautiful graph. As you move the sliders, the graph transforms in real-time. Better yet, you can overlay the before-and-after graphs to compare them, allowing you to intuitively find the perfect balance.

◆ Structure Your World with Entities
Individually manage groups of parameters (Entities) like "Player" and "Enemy," or "Product A" and "Product B." Handle complex interactions between entities, such as {Player:Attack} - {Enemy:Defense}, all within this single tool.

◆ Organize Your Thoughts by Reusing Formulas
A formula you create (e.g., Base Damage) can be called from another formula using {f:Base Damage}. Break down complex calculations into reusable components to keep your thoughts clear.

【Key Use Cases】

・Theorycrafting and calculating damage for RPGs and simulation games.
・Financial simulations for investments (compound interest), loan repayment plans, and more.
・A mobile alternative to Excel or spreadsheets for "What-if analysis."
・Interactive learning and research of physics and chemistry formulas by adjusting variables.
・Business forecasting and break-even point analysis.
