Formula Lab
Read full descriptionHide 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. Unleash your spirit of inquiry. ■ Subscription - Premium Plan 1-Month Plan Enjoy an ad-free, unrestricted experience for one month. ■ About Auto-Renewable Subscriptions Your subscription will automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period. ■ How to Cancel You can cancel your subscription by navigating to Settings > iTunes Store & App Store > Apple ID > View Apple ID > Subscriptions. ■ Restoring Purchases If you have an active subscription, you can restore it via the "Restore Purchase" option. ■ Cancellation Policy Cancellations can only be made through the method described above. ■ Privacy Policy https://myappsintro.web.app/page/privacypolicy/ ■ Terms of Use (EULA) https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: 物理計算機 at none against Formula Lab's 1. Formula Lab's advantage is device support and iOS requirement (13.0 vs 15.5). On price there is nothing between them.

Both are free to download. Formula Lab sells 1 in-app purchase, starting at $1.99 per month. 物理計算機 asks for nothing beyond the download.
