## What is Site Progress Generator?

S-Curve, Gantt chart and delay tracker for site managers, contractors, and PMs. Enter your work items, get auto-calculated planned progress S-curve and Gantt instantly. Fill in actual percentages — delay calculated on the spot.

One-time purchase. No subscription. No ads. No data collected. Fully offline.

Stop wrangling Excel sheets for progress reports.

【Auto-calculated】
- Per-item weight (by contract amount OR by duration)
- Cumulative planned progress S-curve (weekly)
- Gantt chart: light = planned, dark = actual
- Delay % = planned cumulative − actual cumulative

【Delay alert】
At the data date, planned vs actual at a glance. Red text when delay exceeds threshold (adjustable, default 5%).

【Export】
One-tap PDF progress report (with S-curve, Gantt, item details) or CSV. Hand to owner, supervisor, or authority.

Fully offline. No login. No network. No personal data collected.

* Progress and delay are estimates based on input data. Whether delay constitutes breach, liability, and acceleration are governed by your contract and authority decisions.
