Digital lighter apps had a brief but memorable moment as a trendy accessory during concerts and live performances. I remember using one myself at a music festival a few years back. The idea was simple yet brilliant: instead of pulling out a traditional lighter, you could pull out your phone and activate the app to simulate the glow of a lighter. It created a cool, collective ambiance among the crowd without the risk of fire or running out of fuel. What made these apps especially appealing was their ability to sync with music or crowd movements, enhancing the communal feeling. Some even allowed customization of the flame color or flickering speed, letting users express themselves uniquely. While they’ve since faded into obscurity as smartphone capabilities evolved and audiences sought new ways to engage, the memory of waving glowing phones during emotional ballads remains vivid. These apps also reflected a shift in technology intersecting with traditional concert rituals—transforming a simple gesture into a digital experience. Though the trend eventually waned, it marked an innovative chapter in how technology can augment live events. For anyone who attended concerts around the early 2010s, these digital lighters were definitely the 'cool thing' to have, capturing a moment where digital culture met live music in a fun and light-hearted way.
