About this app

Unit converter Pro is the 6th set of Smart Tools® collection.
This app includes Currency (money, Bitcoin) exchange rates. This app has no ads, and ads are replaced by useful texts.

There are a lot of unit conversion apps on the market. However, most are inconvenient and difficult to use because of poor and complicated UI.
This app has intuitive and simple UI, that is designed for casual user like you. Trust me.

I've sorted essential unit sets for your daily life into 4 categories.

- Basic : length (distance), area, weight (mass), volume (capacity)
- Living : exchange rate, temperature, time, speed, shoes, clothing, hat, ring
- Science : pressure, force, work (energy), power, torque, flow, current, voltage, density, viscosity, concentration, astronomy
- Misc. : angle, data, fuel efficiency, cooking, illuminance, radiation, prefix, binary, time zone, blood sugar, hardness, AWG

It shows different unit sets depending on user's country. When you need more units, please send me an email at androidboy1@gmail.com.

Works great. Easy to use and gets the job done. Best $2.50 I ever spent to get rid of the add. I've been using the "free" version for years, but recently the ads became overwhelming. I fully sympathize with the developer on his motivation and had no problem or complaint in going"ad free".

Very good app. it gets the job done perfectly well. Could do with some more customisation options (fonts & size, more background colours). Otherwise, the app is very good. Well worth it.

The font size depends on the phone's default settings. We will add more styles.

Fantastically useful app, been using the free version for years, very happy to support and pay to use it! The latest update to the free one brought some very intrusive advertising (which may be counter productive and put off new people trying it for the first time!). It would be good to see a little more customisation, but the added functionality is great!
