## What is CalcKeep?

Turn calculations you repeat into calculators you can keep. Start with a template, enter your own formula, or get help from an external AI assistant. Save your calculator, then change a few numbers whenever you need it.

Start with an everyday task
Work out coffee ratios, add a tip and split a bill, estimate a project quote, or calculate ingredients for a bread or candle batch. Browse templates by category or search for your task. Try the example numbers, then save a copy with your own name and default values. Download new and corrected templates when connected and keep them available offline.

Make a calculator your way
Enter a formula and CalcKeep turns its variables into inputs you can name. Set optional default values, label units, and add more results. Save a calculator before entering all its numbers, then calculate when you need it. Start with the built-in example or use shortcuts above the keyboard. A searchable unit picker helps label inputs and results; selecting a unit does not convert your numbers.

Create with help from your AI
Describe your calculation and copy the prompt to an external AI assistant. Answer questions in that conversation, then paste its final calculator reply back into CalcKeep. Review the formulas and try a calculation you can check before saving. AI assistance takes place outside the app; CalcKeep does not include an AI chat service or its fees. An example request and a short in-app guide help you get started.

Change the numbers. See the results.
Open a saved calculator, enter values for your current task, and tap Calculate. Get one result or several together. See the formulas and how your numbers fit in, then edit or duplicate your calculator when your rules change.

Use your preferred language
Choose English or Simplified Chinese inside Settings. Select the template language separately. Manual formulas can keep your original variable names in Chinese and other supported scripts. Existing personal names, formulas and descriptions stay as you wrote them. The in-app guide is available in English and Chinese.

Keep and sync your calculators
Saved calculations run locally and work offline. Personal calculators sync through your private iCloud database to supported devices using the same iCloud account. iCloud schedules transfers, so changes may take time to appear on another device. No separate CalcKeep account is required. Export an independent backup to Files or share it to your Mac, and import it when needed. Backups contain the data saved when you export them. Public templates and their updates are separate from your personal library.

Free and Pro
Use all templates, including downloaded templates, for free with your own numbers. View formulas and examples, or create and trial a personal calculator before subscribing. CalcKeep Pro lets you save, edit and reuse unlimited personal calculators with your own formulas and optional defaults.

Pro is available monthly or yearly. Eligible yearly subscribers can receive a 7-day free trial. Plans renew automatically unless canceled; the app shows your local price and trial eligibility before purchase. If Pro expires, saved calculators remain available to view, delete and export. Template calculations and backup import and export remain free. Purchasing and restoring require a connection to Apple.

Calculators, templates, AI replies and software can contain errors. Independently check important results, units and assumptions.
