Convert started as a simple question: why do I need five different apps to convert units, calculate tips, and check currency rates? Today, I'm excited to share what we've built - a single app that handles all of it.
31 Mini Apps, One Download
Convert isn't just a unit converter. It's a collection of 31 specialized tools organized into categories you actually use:
- Money - Currency converter with 150+ live rates, tip calculator, discount calculator, split bill
- Time - Time zone converter, world clock, date calculator, countdown timer, age calculator
- Cooking - Ingredient converter, oven temperature, recipe scaler
- Math - Scientific calculator, percentage calculator, fraction converter
- Home - Paint calculator, tile calculator, concrete estimator
- Design - Color converter (HEX/RGB/HSL), DPI calculator, screen size calculator
18 of these are completely free. Convert Pro unlocks the remaining 13 specialized calculators for home improvement, design work, and finance.
Just Type What You Need
The search bar understands natural language. Type "how many cups in 500ml" or "150 lbs to stone" and Convert figures out what you mean. No need to navigate through menus or remember which category something belongs to.
Behind the scenes, we're using AI to parse your query - but with a local fallback so it works offline too. The goal is simple: you shouldn't have to learn how the app works. Just ask your question.
Currency Alerts That Actually Work
Traveling soon? Set a target exchange rate and Convert will notify you when it's reached. We pull live rates for 150+ currencies and check them in the background, so you never miss a favorable rate.
This was a feature I built for myself after missing a good GBP/EUR rate before a trip. Now it's one of the most-used features in the app.
Everywhere You Need It
Convert runs natively on iPhone, iPad, Apple Watch, and Mac. Your conversion history and saved calculations sync across all your devices via iCloud.
There's also a home screen widget showing your most recent conversion, and full Siri Shortcuts support for automation.
Available Now
Convert is free to download with 18 mini apps included. Convert Pro unlocks everything for a small subscription, with lifetime purchase options if you prefer to pay once.
