ChallengerHub (iOS): Social challenges & habit tracking with friends

Hi Product Hunt 👋 I’m a full-time software developer, and ChallengerHub is a side project I built to solve a personal problem — staying consistent alone never worked for me. Before this, we tried keeping ourselves accountable through group chats in messengers, but those quickly turned into noise and stopped working. That’s when I decided to build a simple, focused app designed specifically for social challenges and daily accountability. ChallengerHub turns goals into social challenges so you can stay accountable together with friends through daily check-ins and shared progress. The app has been live on the App Store for a few days, and today I’m excited to finally share it with the Product Hunt community. I’d love your honest feedback — what feels missing, confusing, or especially useful. Thanks for checking it out 🙏
