My favourite piece of technology

My favorite piece of technology is my cellphone. I have an iPhone 6s. I bought it last year, before join university, saving money of my salary. 
It is very useful in my university life. To see u-cursos platform, do some homework, search information in class and breaks, send e-mails, etc. 
And in my daily life I use it to see the hour, check the bus times, review my social medias as Instagram and WhatsApp, listen to music, take some photos, and other things.
Besides, I use it in the gym, to take care of my health, watching routine videos.
I use it all the time, every day, but I don't think I have and addiction jajaja. I try to use all the function it have. And that's the most important reason to like it, because I think it is multifunctional, and it works very well to me in every aspect of my life.  
I think I can live without it, but I don't want to get it away.
