WIV: Calculator & Converter

Make everyday calculations in one place with WIV: Calculator & Converter, formerly WorkinVirtual Tools.

40 free tools cover everyday maths, conversions, money planning, dates, time, study and practical calculations. Use a scientific calculator, fractions and mixed numbers, percentages, unit conversions, currency references, GPA, equations, world time and more.

CHOOSE YOUR LANGUAGE
Use English, Urdu, Simplified Chinese, Traditional Chinese, Japanese, Korean or Indonesian. The app follows a supported device language, falls back to English, and also lets you choose a language yourself.

CALCULATE AND KEEP TRACK
Type values, review results, save useful calculations and reopen your history. Local backup and restore are available. Calculations stay on your device unless you explicitly export or share them.

OPTIONAL VOICE INPUT
Use your phone's speech-recognition service for supported numeric fields. Review the recognized text before accepting a value. Recognition availability, supported languages and internet requirements depend on your phone and provider. Typing is always available.

CURRENCY REFERENCES
Convert between 18 supported currencies. Refresh manually or enable an optional daily check while the converter is open. The rate date is visible, and the last saved reference remains available offline. These are daily reference rates, not live bank, card or money-transfer quotes. Changing a preferred currency label does not convert an existing amount.

FREE TOOLS, OPTIONAL REWARD
Tools remain free whether or not an ad is available. Where available, you can choose to watch a rewarded video for 30 minutes without banner ads. No purchase or video is required to perform calculations.

REQUEST A TOOL OR SERVICE
Send a suggestion or problem report through a reviewable draft in your email app. You choose whether to send it, and replies arrive by email, not in an in-app chat. No phone-number field is required.

Most calculations work offline. New currency rates, ads, email delivery and some speech-recognition services need internet access. Money and tax results are planning estimates, not financial or legal advice.
