About Mila's Unit Converter PRO
Before Mila's Tools became a free App Store staple, Mila's Unit Converter PRO was the paid iPhone app that put hundreds of units across 26 categories in one place. It is the Apple Staff Pick predecessor that established the fast, type-and-convert workflow thousands of reviewers still describe as the best quick-reference converter on iOS.
The original paid Mila's Tools experience
Unit Converter PRO is a legacy one-time purchase — not the current free Unit Converter: Mila's Tools. It targets users who bought the classic app years ago or who want the full original category set without a subscription. Conversions happen as you type: pick a category, enter a value, and every related unit updates instantly. No dials, no submit button.
26 conversion categories
- Area, length, weight, volume, temperature, and pressure
- Blood sugar, fuel economy, fractions, and slope
- Energy, power, force, torque, velocity, and flow rate
- Density, capacitance, illuminance, and data transfer rates
- Bits & bytes, dates, numbers, time, and shoes
Built for daily use
- Live multi-unit output — all units in a category convert as you enter any value
- Search — jump to categories and units without scrolling
- Customization — hide categories and units you never touch; set decimal precision up to 10 places
- Locale formats — US, European, Swiss, French, and Indian number styles
- Offline — every conversion runs on your iPhone with no network required
- Specialized tools — grouped views for length, weight, volume, area, pressure, and torque; dedicated blood sugar and fuel converters
Frequently asked questions
- How is PRO different from the free Mila's Tools unit converter?
- Unit Converter PRO is the earlier paid title with 26 categories. The free Unit Converter: Mila's Tools adds more categories (29), compound units, a date calculator, ring sizes, historical measures, and ongoing cross-platform updates.
- Why do reviews mention an Apple Staff Pick?
- That recognition belongs to the Mila's Tools family that grew from this app — the paid PRO release was the foundation Apple featured.
- Do I need internet to convert?
- No. All math runs locally on your device.
- Can I hide units I do not use?
- Yes. Toggle categories and individual units on or off so the interface shows only what you need.
- Is PRO still updated?
- PRO is a legacy paid app. Active development focuses on the free Mila's Tools line, but PRO remains available for existing users and anyone who prefers the classic paid version.
