Enjoy tonight’s New Year’s Eve fireworks show off Waikiki with the help of your smartphone.

New this year is the free Fireworks by Grucci app that provides access to the music accompanying the choreographed show at midnight. Just download the app and tap on the Waikiki Improvement Association logo to listen.

A radio works too: Tune into Hawaiian 105 KINE FM.

More than 1,800 shells will be launched from an offshore barge, bursting into displays of palm trees, rings, strobes, sparkling fans, falling leaves and other designs that will be visible along Waikiki Beach. The fireworks show will start at 11:55 p.m., with a countdown shell fired every minute until a minute before midnight to get the crowd’s attention. Then, at the stroke of midnight, a barrage of colorful salutes accompanied by “Auld Lang Syne” will signal the start of 2016 in Hawaii. Music by local recording artists also will be featured during the 10- to 12-minute fireworks display.

The event is sponsored by the Waikiki Improvement Association and a host of hotels, retailers and other businesses.

You can also head downtown to enjoy the fireworks display at the Aloha Tower Marketplace, which will have hourly firework salutes from 9 p.m., concluding with a 15-minute show at midnight, and to the Waialae Beach area to take in the Kahala Hotel & Resort’s music-synchronized fireworks show at midnight.
