Why switch from SparkShift?
Positioned for apprentices, not professionals — 200+ calculators but no permit-ready output, no project management, and no transparent methodology for inspector review
- Get permit-ready calculation packages instead of copying results by hand
- Professional-grade output that inspectors accept without follow-up calls
- Organize calculations by project instead of scrolling through a history list
