東急でんきガス is the official app developed by 株式会社 東急パワーサプライ. Once you log in, you can access a range of useful features. With this app, you can easily monitor your electricity usage (hourly, daily, weekly, and monthly) as well as your gas usage (monthly). You can also check your monthly usage charges and review the breakdown of costs. Additionally, the app allows you to make various changes to your account information.

One unique feature of 東急でんきガス is the accumulation of Lemons, the in-app points. When you collect enough Lemons, you can enter giveaways and win exciting prizes! Lemons can be earned by paying your monthly bills, tracking your daily steps, checking in, and playing mini-games.
