Excellent Conversion App

Having been using Convertbot app for quite some time, it no longer works with IOS 11 and has not been updated by the developers, so looked for an alternative. Units Plus looked a good replacement so downloaded the free version. The colourful layout is very appealing and it does all you want it to and is easy to use. After using a few days, decided it worthy enough to upgrade to the paid version. Like the fact that you can save your favourite units to convert, albeit only up to 4, but it still gets 5 stars from me!

Great App can be better

The app is great works fast and accurate. I would like to see additional features such as working out area from a diameter and have a much user friendly operation. It's worth the spend.

The most complete app of this type

The most incredible app on my phone. I use it every day to convert currency, and weight, but increasingly beginning to use most of its facilities. Now I can't imagine not having it on my phone.
