ZEUS Core App: a new offer without a phone call.
In the app, an energy supplier's customers see their contracts, supply points, consumption and live electricity prices. They can price a new offer in three steps, and an AI assistant answers everyday questions. They don't need to call a sales rep, who gets more time for new deals.
A customer portal for your pocket
The ZEUS Core web system serves sales reps and the back office. Customers need something else: a quick look at their contract, consumption and today's electricity price. When they are ready, they want to price a new offer themselves, without calling a sales rep. So we built a separate mobile app, designed from the start for one-handed use.
The app uses the same data as the web system. What a rep enters in the CRM, the customer sees on their phone, and new web features reach the app without doing the work twice. Sign-in is secure, and new accounts are approved by a sales rep.
The app is ready for release. We submitted the iPhone version to App Store Connect in August 2026, and the Android version is built from the same code.
Challenge
Energy customers want to know what they pay and when electricity is cheap. They don't want to phone anyone for it, and a web portal is awkward to use on a phone.
Solution
An app with five tabs: overview, contracts, consumption, live prices and assistant. Plus a new offer in three steps, documents, notifications, profile and security. All connected to the same system as the web.
Result
The app is connected to the live system and ready for release. We submitted the iPhone version to App Store Connect in August 2026, and the Android version is built from the same code. Customers get self-service, and sales reps get fewer routine calls.
