In a nutshell…

A smart speedo for when you’re sweating your guts out, and simply must know how much ground you’ve pounded in the process. Ideal for gathering data on your run, comparing it to previous efforts and tweaking performance. Personal trainers, pah! This svelte piece of software bites its thumb at those ruthless 100 quid-an-hour perma-tanned menaces.

Judgement time!

Sports Tracker is a boon for fitness freaks. Switch it on, tell it the type of activity you’re going to do and it’ll track the distance covered, speed, pace, even altitude.

It’s all done using GPS, so it’s really only practical for N95, E90 or 6110 owners at the moment, unless you want to be burdened with a Bluetooth add-on while jogging round the block. Us neither.

It’ll watch your every move as you sweat off the calories, even plotting a map of your route (you’ll see from the screenshots that it’s also useful for measuring the distance to the local corner shop, for that emergency pack of caramel choc digestives).

Each time you stop exercising, Sports Tracker saves your progress to a calendar, showing at a glance any days you’ve sat on your backside and how much exercise you got on the days you didn’t.

Of course, as it’s using GPS constantly it’s a drain on battery life, but if you’re returning home after each exercise it’s no great hardship, so long as you remember to top it up with juice.

Overall it’s an incredibly well thought-out app. You can even rotate the screen (in case you’re wearing the phone on an arm-band).

If you’re more subtle, there’s no need to worry. The GPS works well even when pocketed – even continuing to track movement for a short while as you head indoors.

A good selection of activities, and some custom options, let you track any exercise you like. Check it out – it’s free, well made and, if you’ll forgive the pun (don’t), definitely worth taking for a trial run. Sorry.
