Clear water, every season. Enter your pool or hot tub test results and Pool Almanac tells you exactly what to add, how much, and in what order. Amounts come in what you actually pour, like "about 3/4 of a 1-gallon jug of 10% liquid chlorine."
Logging a test takes about 30 seconds. Drippy, your pool's sidekick, walks you through setup and lets you know at a glance how your water is doing.
WHAT IT DOES
- Exact amounts for any brand. Doses are worked out from your pool's size and your stabilizer (CYA) level, for liquid chlorine, tablets, salt pools and bromine hot tubs. Tap Why? on any step to see the math.
- A plan in the right order. For example: add the acid, wait 30 minutes, then add chlorine. Mark each step done and the app reminds you when to test again.
- A record of everything. Every test, chemical, chore and note in one place, with trends. It works offline and syncs later.
- Help with a green pool. A free step-by-step algae rescue plan.
- Ask the pool coach. Answers use your own test history, weather and equipment. We never sell your pool data, and your questions aren't sent to outside AI companies.
