About this app
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 ■ Pricing Create 1 custom formula for free. Unlock unlimited formulas with a one-time purchase — not a subscription. No extra fees, no ads. * Results are for reference only and are not a substitute for official values or professional judgment.
