Arara vs Wafer Messenger

Arara is the battery-free wheel-mounted bicycle lighting system.

Arara is the bicycle lighting system that will never need a battery. The wheel-mounted lights are powered by strong neodymium magnets. When a bike’s wheel starts to spin, the lights move past the magnets and the generated electric energy is stored in the capacitor. When it's charged, Arara lights up.

Arara makes a bike easily recognizable from every angle at night, is available in variety of colors, is water-resistant, lightweight, and works at temperatures down to -15 degrees F.

Wafer Messenger is the world's most versatile chat app, allowing you to create real-life like messages and send them to all your contacts; even those who are not on Wafer yet.

Wafer Messenger has been created because nowadays each of us is used to juggle between 4 and 10 chat apps, using all of them at the same time, because none of those apps allows their users to reach everybody. And this is frankly unacceptable.
Wafer aims at becoming, over time, the all-encompassing communication platform.
