The application is free, but the download may cost up to £0.75 in data charges depending on your tariff.
In association with the Guardian Guide, it gives Glastonbury revellers information and stage times for the full festival line-up, the ability to personalise your very own artist schedule for the whole weekend, an interactive map of the site as well as essential festival news, advice and alerts.
Everyone that downloads Orange GlastoNav will also be eligible to receive 50 off an annual subscription to Q Magazine.
In addition this year, there will be competitions running throughout the festival weekend giving Glastonbury revellers the chance to win money-can’t-buy side of stage access to the Pyramid Stage.
At 12pm every day a bull icon will appear on the GlastoNav map showing where you need to go to find a life-size bull on site. Once at the secret location, revellers need to click the icon on the map and enter a code word written on the bull to be in with a chance of winning exclusive side of stage access for one of the featured performances.
Spencer McHugh, brand director at Orange UK, said GlastoNav was the best way to plan the perfect Glastonbury weekend.
“Sharing your schedule with friends means you will never miss meeting up for your favourite bands and GlastoNav will keep you up to date with the latest news and the chance to win side of pyramid stage passes everyday."
The application can be downloaded now from the Orange website or by texting the word GLASTO to 64446.
Full terms and conditions for GlastoNav can be found on the official website.
