Solid Span

Designed for homeowners who are renovating or preparing to renovate, this app introduces a unique three-axis health scoring system inspired by Wan, Tiao, and Tong: the Wan axis tracks total budget execution, the Tiao axis measures whether construction milestones progress smoothly and on schedule, and the Tong axis monitors pass rates for trade inspections including plumbing, electrical, tiling, carpentry, and more. It includes four core capabilities—milestone check-ins, on-site photo documentation, material list verification, and intelligent delay alerts—plus extended features such as budget breakdown analysis, trade inspection checklists, contractor performance tracking, and delay root-cause analysis. It helps homeowners stay fully informed on schedule and spending, take control instead of being led by contractors, and make renovation transparent, manageable, and fully documented.
