These days most people have a smartphone. In fact, it’s hard to think of life before smartphones. Spending precious airtime on SMSs with limited character count or having to actually (shudder) phone someone is thankfully a thing of the past. Of course, that’s not even the half of it. There are thousands of amazing apps out there to make our everyday lives so much easier. As a student, there are apps to help you sleep better, study harder and live better. Here are just three apps that could change your life.     Unitehood If you’re ever in trouble, you’ll be glad you downloaded this app. At the press of a button on your smartphone, a call will be sent to an emergency number and notifies people in your vicinity as well as friends you have on the app. It’s location-based and it tracks you so those closest to you can be alerted if something goes wrong. So, if you’re in Cape Town waiting for roadside assistance and something happens that makes you feel unsafe, you can alert people around you. The app is all about promoting safer communities and encouraging neighbours to look out for each other.    Evernote Organising your life isn’t easy when you’re a student. You don’t live according to a nine to five schedule like those in the working world. Some days you have three lectures and zero assignments and other days you have six tests to study for and a group presentation you haven’t even practiced for. It’s easy to forget the little things and get confused about all those essay due dates. That’s why this app is so great for students. The daily planner isn’t even the main feature. You can use it to record your lectures, keep track of your notes and so much more. It will organise your life, your study notes and everything inbetween.   SleepBot Getting a good night’s sleep is important, especially when you’re a student. Your brain needs time to rest between all the assignments, tests and presentations. But you don’t just need to sleep, you need to sleep well. And that’s what SleepBot is all about. It tracks your sleep activity using your device’s accelerometer and you can even set it to record sounds. Through tracking your sleep activity, the app knows exactly when to wake you up.Of course, if you’ve got an exam in the morning, set a separate alarm because your lecturer doesn’t care if you’ve had a good night’s sleep.   These three apps could change the way you live your life. So, put your smartphone to good use and download them today.   Image: Pexels
