Build your own calculator
Only for iPhone
Free · In‑App Purchases
iPhone
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
