Pool Chemical Logbook
Commercial pool records, exact dosing, offline logging, and monthly PDF logbooks in one app.
Pool Chemical Logbook is the Pool By Engineer Inc. field app for operators who need cleaner chemistry records, clearer dosing guidance, and inspector-ready monthly logs. It is built for commercial pools first, but it also works well for homes and private facilities that want tighter records and simpler water-balance direction.
- Offline-first daily logging
- Cloud sync when service returns
- Inspector-ready PDF exports
- Built for Android and iOS
Generate monthly logbooks that are cleaner to archive, review, email, and present during inspections.
Keep working on site without internet, then sync account data and records when service comes back.
What The App Does
It combines daily chemistry entry, exact product-based dosing, and operational records in one cleaner workflow.
The app is meant to reduce call-backs, loose paperwork, and hand-calculator guesswork. It gives operators a faster way to log readings, calculate corrections, and keep a reliable record for management, audits, and health reviews.
Daily Logging
Record pool and spa chemistry without slowing down field work.
Log pH, free and combined chlorine, alkalinity, calcium hardness, CYA, TDS, temperature, flow, filter PSI, initials, and notes in one operating log.
Chemical Calculator
See product-aware dose guidance before you over-correct the water.
The calculator accounts for common pool products and their side effects so the dose guidance is closer to the way commercial operators actually work.
Operations Record
Export monthly PDFs that are easier to file, share, and review later.
The app supports clear monthly records for inspections, management reporting, and internal review without keeping a separate paper logbook.
Best Fit
Designed for real operating environments.
- Commercial pools and spas
- Hotels, HOAs, apartments, and clubs
- Service companies managing multiple bodies of water
- Residential owners who want neater records and clearer chemistry guidance
