Jolla is a new alternative to iOS, Android and Windows Phone so see what we think of this Sailfish OS smartphone in our video review.

Jolla is a new company on the smartphone scene, setup by ex-Nokia employees. They've created their own mobile operating system and the self-titled smartphone is the first device to come with this new player and rival to iOS and Android.

Sailfish OS is based on MeeGo, Nokia's old open-source operating system which you may remember from the N9 smartphone. The Jolla costs €399, so that's £329 in sterling making it a little more expensive than Google's Nexus 5.

If the design is one thing, it's unique with its rounded edges on opposite side and a style which looks like the device is made of two separate pieces. However, this thing is not very nice to hold in the hand. Its brick like dimensions and weight are not the most ergonomic.

Interchangeable covers contain NFC chips which dictate the look and feel of the interface with different wallpapers and matching theme colours. It's an interesting but definitely gimmick idea – especially when you consider a flimsy piece of plastic will set you back nearly £25.

Of the major mobile operating systems, Sailfish is closest to BlackBerry 10. It's got no navigation buttons so everything is based on gestures.

Rather than the side-to-side navigation most people are used to in iOS and Android, Sailfish is laid out vertically. Top to bottom you have a lockscreen, homescreen and an app menu.

Swiping in from the sides, top or bottom will respectively close apps, return you to the homescreen and display your notifications. The screen size means that it's all too easy to accidental exit apps.

It's a system which is difficult to get used to and doesn't seem very intuitive to us. It seems like it's just trying to be different to the competition.

There are a limited number of apps, as you'd expect from a new platform but there is the support for Android apps. You can't just use the Google Play Store though, so you'll need to rely on third-party stores like Yandex. Not all the Android we've tried run smoothly either.

Hardware is averagely mid-ranged with a 4.5in qHD screen which isn't up to the usual IPS standard and an 8Mp camera which only takes decent photos when you're outside in good light.

A dual-core processor inside provides generally good performance with most apps opening quickly and navigations smooth. But both gaming and web browsing are disappointingly laggy.

The Jolla is an interesting new smartphone with its eye-catching Sailfish OS. However, it's too expensive for the average hardware on offer, a confusing interface and a reliance on third-party Android app stores.
