Calcraft - Formula calculator

Calcraft turns the calculations you repeat every day into your own reusable calculator. Save a formula once, then just enter the numbers.

■ Sound familiar? ・Re-typing the same calculation from scratch every time ・Forgetting your margin or cost formulas each time ・A stock calculator forgets your formula — one typo and you start over

■ What you can do [Build your own formulas] Name a formula and register the values that change (price, cost…). Just enter the numbers for an instant result.

[Reuse them anytime] Saved formulas stay ready. Pricing, cost, and quotes — the same steps, every time.

[Ready-made formulas included] Discounted price, profit margin (%), and BMI are built in. Just add your own frequently-used formulas and customize.

[Add notes to formulas] Jot down rules like "shipping not included" so you never forget your own conditions.

[Automatic iCloud backup] Your formulas are saved to iCloud automatically. Get a new iPhone, install the app, and everything is back. The settings screen shows when your data was last saved. Manual export and restore are still available too.

[Open it from Control Center] Swipe down from the top-right corner and tap once to launch the app, so you can calculate the moment you think of it. Requires iOS 18 or later.

[Dark mode & multi-language] Light / Dark / System modes. Available in Japanese and English.

■ Great for ・Resellers & online sellers checking margins and costs ・Small businesses figuring pricing, tax, and markup daily ・Freelancers building quotes or hourly-rate conversions ・Anyone who wants fast discounts, unit prices, or BMI
