Reviews from the App Store
This app is excellent. Been using it for years whenever I need a conversion, be it temperature, distance, volume, rate of speed - any conversion you could possibly need! Precise and very simple to use.
I am a journeyman elevator constructor. Our company uses the metric system for everything, including speed. The governing authority wants everything in Imperial. I have to make detailed reports for both, and this app makes it painless. The mm/s unit that was added on the last revision was at my request.
I encounter a variety of English Standard and Metric bolts and liquid measurements, and temperature settings. Given a tray full of wrenches, it helps to know that 13 mm and 19 mm are close enough to half inch and three quarters of an inch that the slightly larger will do the job.
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

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.
