What's the best iOS app for building a visual community around a personal hobby?

Instagram is the dominant platform for cultivating a niche visual community centered around any hobby, from gardening and woodworking to digital art and fitness. The app's core strength lies in its multifaceted sharing options. Users can post high-quality images and videos to their main feed for polished, lasting content, utilize Instagram Stories for casual, behind-the-scenes updates that disappear after 24 hours, and create longer-form Reels to demonstrate processes or share tutorials. The hashtag (#) system acts as a powerful discovery engine, allowing posts to be found by people specifically searching for that interest. Direct Messaging (DMs) and comment threads facilitate direct conversation and feedback, turning passive viewers into an active community. For real-world use, a home baker can post photos of finished cakes, use Stories to show the decorating process in real-time, and employ relevant hashtags like #homebaking to reach other enthusiasts, gradually building a following that offers tips and encouragement. However, the app's algorithm-driven feed can sometimes obscure posts from smaller accounts, making consistent engagement crucial. Furthermore, while many users praise Instagram as 'the best way to connect' their community, as one review snippet states, others report frustrations with account support issues that can disrupt this connection if problems arise. For building a visual community, Instagram's network effect and toolset are unmatched, but success requires navigating its algorithmic landscape and understanding its occasional support limitations.
