Reevolt is a free iPhone app developed by Kevin Sala that aims to help households save energy while also rewarding them for their efforts. With Reevolt, users can connect their Linky energy meter to the app and track their energy consumption. The app encourages users to consume less energy than the previous day, and rewards them by adding to their energy savings fund.

One of the key features of Reevolt is the energy savings fund, or "cagnotte," which can be used to pay for purchases both in-store and online. When users make a purchase, Reevolt calculates the amount to be deducted from their energy savings fund, allowing them to pay less and generate a coupon for future use. This not only helps users save on their energy bills but also gives them extra purchasing power.

For those who want to take their energy-saving efforts further, Reevolt offers connected components with built-in artificial intelligence. These components help users identify and eliminate energy waste in their homes. Additionally, the Reevolt components themselves contribute to the energy savings fund when they are turned off, providing added convenience and savings.

Reevolt is a user-friendly app that empowers households to save energy and be rewarded for their efforts. It offers a unique way to reduce energy consumption and lower energy bills, all while enjoying the benefits of increased purchasing power.
