Tempo Infos Couleur du Jour, developed by Hello Watt, is an Android application that provides users with information about the color of the day and the following day. This app is specifically designed for users who have opted for the Tempo option from EDF, which offers advantageous electricity prices for 343 days of the year. During the remaining 22 days, users are encouraged to reduce their electricity consumption during peak winter consumption periods.

The Tempo option offers different tariffs based on the color of the day. For Blue days (300 days/year), users can enjoy highly advantageous electricity prices, with 30% savings on the price of electricity during peak hours and 40% savings during off-peak hours. White days (43 days/year) also offer advantages, with 10% savings during peak hours and 24% savings during off-peak hours. However, on Red days (22 days/year), electricity prices are significantly higher, with peak hour kWh prices up to three times higher. Nevertheless, users can still benefit from 15% savings during off-peak hours.

This app also provides users with a historical record of Tempo days and allows them to receive notifications for Red Tempo days. Additionally, Tempo Infos Couleur du Jour offers tips on how to manage and reduce energy consumption through the Hello Watt energy tracking app.

With Tempo Infos Couleur du Jour, users can easily stay informed about the color of the day and make informed decisions to optimize their electricity usage and save money.
