In an interesting attempt to make the life of a tradesman easier, Installer Online have come up with an interesting new iPhone app that may just lighten your toolkit somewhat and make sure you're never without some important tools.

The free app is named InstallerTOOLBOX and has been developed "provide a range of functions that will make every day - and every installation - that little bit more straightforward." It incoporates a number of things that are essential to your job and keeps them all within your phone, meaning they'll be in your pocket at all times!

Altogether the app includes:

• A TORCH for when you need that extra bit of light dealing with pipes under the sink or rummaging around in boiler cupboards. It features three brightness settings to give you maximum visibility.
• A quick, easy and above all accurate SPIRIT LEVEL that "measures down to 0.1° to ensure that it is more than just a gimmicky add-on". It can also switch between horizontal and vertical settings.
• A UNIT CONVERTER that covers everything from temperature to velocity so that you don't have to make any rough calculations in your head or require a pocket conversion guide. All you need to do is enter the amount and choose what units you want it in.
• Finally, every tradesman loses a pen once in a while so here you can do away with pen and paper for good with the JOB SHEET. With this you can make notes, jot down job specs, prepare invoices and more! It also allows you to build you a record of every project you complete, including photo attachments. These are saved to the app and can be emailed out to colleagues, customers and whoever else may need them.
