Verified dating and relationship app browse profiles, chat in real time, and video call via WebRTC, with Free, Gold, and Platinum membership tiers.

AfroHoney is a verified dating and relationship app I built from scratch for a US-based client, made for people looking for genuine connections within their community.

Users create detailed profiles, browse others through a discovery feed with filters for age, gender, location, and preferences, and send expressions of interest (EOI) to people they like. Once connected, they chat in real time with typing indicators and read receipts, and can video call each other directly inside the app using WebRTC.

The app runs three membership tiers  Free, Gold, and Platinum each unlocking more daily likes, filters, and features, with gentle upgrade prompts when free users reach their limits. Payments are handled through multiple methods: in-app purchases, Stripe, and PayPal, giving users flexible, secure checkout.

I delivered the full package the React Native mobile app, the marketing website, and the admin panel. Both iOS and Android apps passed store review and are live today with real users making verified connections.

Hafiz is always a great guy to work with and it is with great satisfaction giving 5 star on every delivery
