Onboarding is designed for clarity and trust from the first tap. The welcome screen sets the tone with a promise: fast, reliable power payments. The sign-up screen is stripped down to essentials to reduce drop-off. For verification, We chose link-based email/OTP flows that balance security with simplicity, ensuring users feel safe while not overburdened with steps.

The dashboard is designed as the control center, giving users a quick snapshot of their wallet balance, Purchase summary, recent activity, and key actions (like topping up or paying bills). Transaction history is easily accessible so users can track payments and instantly see their purchased tokens or receipts, building transparency and confidence.

Paying bills is the core, so it’s kept short and intuitive. The form allows either manual entry or quick selection from saved meters to reduce clicks. An order summary confirms details before payment, reducing errors. Payment methods are shown in a familiar, clean layout to minimize friction at the most critical step.

Transactions focuses on what happens after payment, the most sensitive part of the journey. Users need instant reassurance that their money was well spent, so the success screen delivers the purchased token immediately, with thoughtful accessibility features: a one-tap copy button and a read-aloud option for visually impaired or multitasking users. The transaction details and receipt screens go further by giving users clear, itemized records they can save or share, ensuring complete transparency and boosting confidence in the app.

The profile area focuses on control and personalization. Users can update account details securely, manage saved meters for convenience, and quickly access help if something goes wrong. The goal here was to create reassurance and support. Users know they can always edit, manage, or get assistance without confusion.

• Faster payments: Tokens delivered in seconds in app because sms providers might experience delays and downtime occasionally.

• Fewer disputes: Automatic refunds reduce complaints.

• Convenience: Saved meters & receipts streamline user experience.

• Trust: Clear feedback at every stage increases retention.

Building user trust requires designing for edge cases (failed payments, empty states, refunds) as much as for the happy path.
