Hi. I've been building TiiHub for 2+ years. It launches today on the App Store. Walkthrough video attached.
I'm walking the Apollo path: build natively on one platform, polish it deeply, then expand. So I built a niche social network for spatial media (spatial photos and videos, 360° content, LiDAR object scans, doodles, plus regular photo/video) with Reddit's social mechanics underneath. Not trying to replace Reddit broadly; doing one corner well at the bar Apollo earned its reputation on.

What I kept from Reddit:

• Hubs (subreddits) with full mod tools and audit logs
• Leaf karma, separate post/comment tallies, atomic against brigades
• Threaded comments, mod pinning, locked threads
• Sorts: Hot, Top, New, Controversial (with time windows)
• Feeds: Home, Popular, Latest, per-hub
• Mentions, bookmarks, blocking, content appeals

What I did differently:

• Hub-optional posts: Post to your profile (Facebook/Instagram-style), not just to a Hub.
• Two social graphs: Unilateral follows (Twitter) + mutual friends (Facebook), with a friends-only feed filter.
• First-class spatial media: 360°, spatial photo/video, LiDAR scans, floor plans, USDZ 3D models. Doodles (Vision OS only for the moment)
• In-app capture: iPhone LiDAR scanning, Room Capture, on-device photogrammetry, all built in.
• AI-assisted moderation (experimental): Hub-level auto-flagging plus AI reviewing moderator activity itself for abuse.

Centralized, closed source, iOS + visionOS only.

I'll gladly answer any questions and love hearing feedback. Curious whether non-spatial communities forming on TiiHub (writers, music, coding) is something you'd want, or if the niche framing feels too narrow regardless.
