A free app commissioned by Kensington and Chelsea RBLC is being touted as 'the must-have guide' to this weekend's Notting Hill Carnival.
Carnival-goers are being encouraged to use the app, which features a map of the route, locations of the sound stages, the judging point, first aid and safety zones, and food stalls.
London mayor Boris Johnson said: 'This useful free app will help guide thousands of people around the carnival footprint to enjoy the array of floats, sounds and delicious Caribbean cuisines.
'It will also come in handy when planning entrance and exit points, ensuring you make the most of your celebrations this bank holiday weekend.
'With the 50th anniversary of steel pan, colourful costume parades and a wealth of live music acts, I hope everyone has a truly amazing carnival.'
Hundreds of musicians and dancers are expected to join floats for a procession through west London on Sunday and Bank Holiday Monday for Europe's biggest street carnival event.
