FloorFlow - Feng Shui Planner: Room planning with feng shui, lighting & design validation

Hey Product Hunt! 👋 I built FloorFlow because every room planner I tried had the same problem: they told me whether my furniture fit, but never whether it worked. There's a real gap in this market. Existing apps are incredible at visualization, but none of them validate whether your layout makes spatial sense. No chi flow analysis, no lighting coverage checks, no ergonomic clearance validation. You'd need four separate tools (and a feng shui consultant) to get what FloorFlow gives you in one canvas. A few things that make FloorFlow different: → The feng shui engine uses actual A* pathfinding to model how energy moves through a room - it's not a checklist, it genuinely understands spatial circulation. → The lighting system analyzes coverage across four layers and flags gaps, not just whether you have a lamp in the room. → The interior design validator checks against real professional standards - NKBA kitchen guidelines, OSHA workstation specs, ADA clearances - and explains every warning in plain language. → The AI visualization uses Gemini to generate renders from your actual floor plan, not a generic stock room. Who it's for: Anyone moving or redecorating who wants to get it right before buying Feng shui practitioners who need a proper spatial tool Remote workers designing a home office that's ergonomically sound Anyone who's ever moved furniture three times and still felt like something was off It's a one-time purchase on iOS. No tiers, no paywalls, no subscription - every feature included. Would love to hear your questions and feedback. Happy to go deep on any of the analysis systems! 🙏
