How PoolChem Tracker works
From test kit to balanced water — and everything else that keeps a pool running. No chemistry background needed.
Test your water and enter the results
Use whatever test kit or strips you already have. Enter your readings — free chlorine, pH, alkalinity, CYA, calcium hardness, and water temperature.
- Takes about 30 seconds to log
- Supports all common test parameters
- Auto-calculates combined chlorine from FC and TC
See exactly what your water needs
PoolChem Tracker analyzes every reading against ideal ranges and calculates your pool's overall health score — a single 0-100 number that tells you where you stand.
- Health score based on up to five parameters — only readings you've entered count
- Color-coded status for every reading
- Flags problems before they get expensive
Know if your water is safe — or silently causing damage
PoolChem Tracker calculates your LSI (Langelier Saturation Index) automatically. This tells you whether your water is corrosive, scale-forming, or perfectly balanced.
- Full LSI formula with CYA correction
- Clear status: corrosive, balanced, or scaling
- Catches problems before they cause expensive damage
Spot patterns and catch drift early
Every reading builds your history. Interactive trend charts show how each parameter changes over weeks and months — so you can see what's working and what's drifting.
- Interactive charts for every parameter
- Health score and LSI trends over time
- Spot seasonal patterns
- Export your data as CSV anytime
Track every task that keeps your pool running
Beyond chemistry, a healthy pool needs regular maintenance. The Tasks tab keeps your filter cleanings, SWG cell checks, and equipment inspections organized in one place.
- Log maintenance as it happens
- See what's overdue at a glance
- Covers filter, SWG, equipment, and more
What's under the hood
⚖️ LSI Calculator
Full Langelier Saturation Index with CYA-corrected alkalinity, polynomial temperature factors, and salt-adjusted TDS. Not the simplified version. Calculates from your actual test readings, not backwards from a target LSI.
📊 Health Score
Up to five components scored out of 20 — FC, combined chlorine, pH, LSI, and CYA. Only the readings you've entered contribute, and the score still reports out of 100. One number that tells you if your water is balanced.
💊 Smart Dosing
Chemical recommendations based on your pool volume, current readings, and target ranges. Prioritized so you fix the most important thing first.
📈 Trend Charts
Interactive graphs for every parameter. See how your chemistry changes over weeks and months. Spot seasonal patterns and drift.
🔔 Smart Reminders
Configurable reminders for water testing, filter cleaning, SWG cell maintenance, and chemical inventory checks.
📦 Chemical Inventory
Track what chemicals you have on hand. Know when you're running low before you need to make a pool store run.
🌊 All Pool Types
Chlorine pools, salt water generators, and everything in between. Configure your setup and get tailored recommendations.
✅ Maintenance Tasks
Log filter cleanings, SWG cell checks, equipment inspections, and more. See what's overdue at a glance and keep every recurring task organized in one place.
📤 CSV Export
Export your complete reading history as a CSV file. Import previous readings. Your data is always yours.
Built for trust, not tracking
Your readings, dosing history, and pool settings never leave your device — no account, no cloud, no exceptions.
