Read full description

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.)," and "Loan Payments." Complex formulas 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. 【Perfect for...】 ● Gamers pursuing the ultimate build and theorycrafting in RPGs and simulation games. ● Individuals wanting to compare various scenarios for investments or loan repayment plans. ● Business professionals looking for an easy way to perform "What-if analysis" on their smartphone, as a handy alternative to Excel or spreadsheets. ● Students and researchers who want to interactively learn physics and chemistry formulas by adjusting variables.

Verdict

The call

The clearest difference is ads: ShiftProCalendar at none against Formula Lab's shown. Formula Lab's advantage is iOS requirement (13.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.
