## Description

Pool Math by TFP makes pool care simple and reliable. Designed for Trouble Free Pool users, it tracks chlorine, pH, alkalinity, calcium hardness, stabilizer and salt levels and calculates the exact chemical doses you need. Avoid inaccurate strip scans—enter results from a proper test kit, log tests, and follow precise recommendations to keep water crystal clear and algae-free.

The extension also logs maintenance tasks like backwashing, filter cleaning and SWG cell life, offers a bleach price calculator, data backup/export and a summary dashboard with test and chemical log insights. Premium subscribers get unlimited history, maintenance reminders, cloud sync across devices, unlimited pool/spa setups and CSV import/export. Pool Math reduces pool-store trips and saves money by making pool chemistry easy, accurate, and dependable.

## Review summary

Users praise Pool Math for easy tracking, accurate dosage guidance, and value with a paid plan for long-term pool chemistry tracking. However, frequent subscription gating, reliability problems, mandatory account creation, confusing UI, and misaligned chemical ranges are common complaints. Some users also want more features like multi-language and greater flexibility.

### Pros

- Easy to use and intuitive for tracking pool chemistry
- Accurate dosage calculations and customizable set points
- Good value for the paid subscription / affordable yearly price
- Strong support for long-term tracking of pool chemistry and test results

### Cons

- Subscription model gates core functionality (needs subscription to log more than one entry; perceived as upsell/misleading)
- Reliability and stability issues (bugs, crashes, freezes; issues when resubscribing)
- Mandatory account creation and login; difficulty in demoing without signing up; data loss on reinstall or reset
- Confusing user interface with incomplete instructions and missing calculator/tools
- Ranges and recommendations sometimes misaligned with industry standards (e.g., CA) leading to conflicting notices
