Overview

Sigh is a full-featured social network for iOS and Android. It combines a media-rich feed and stories, post creation from camera and video, real-time chat and calls, follow/notification systems, and both personal and business accounts. Creators and businesses get analytics and performance screens, account upgrades and subscriptions (RevenueCat), QR-based profile sharing, and a complete moderation layer with reporting and blocking.

Challenge

A social app is many products at once — feed, stories, media capture, messaging, calls, profiles, analytics, payments and moderation — all of which must stay fast and smooth on real devices while handling media-heavy content, push notifications and live updates without janking the scroll or draining the battery.

Outcome

A polished, production-grade social app with a fluid media feed, frictionless content creation, real-time messaging, monetization for creators and businesses, and the safety tooling a public network needs.
