Pooli for Pool & Spa Owners

Pooli is built for everyday pool and hot tub care: scan or enter a test, get clear chemical guidance, and keep history, inventory, and equipment in one place. Custom for each body of water you track.

How it works

Run your usual strip or kit test, then enter results or use Pooli SCAN to read a strip with your camera. Pooli calculates what to add, in what order, with the why behind each step.

Testing & water report

  • Track any number of pools and hot tubs
  • Test strip scanning with optional Color Correct Card workflows
  • Reading range bars that show where each result sits versus your targets
  • Lookback for slow-changing parameters so one incomplete test still builds a full water picture
  • Share a water test by email, text, or copy
  • Optional test color styles (match strips or generic)

Treatments & dosing

  • Chemical recipes with proper order of addition
  • Post-dose guidance: wait times for the next chemical, retest, or swim-ready, plus separation tips
  • Adjust toward your preferred target when a reading is already in range
  • Clearer adverse-dose warnings when a full dose would push another parameter out of range
  • Treatment progress: remaining dose, completion, awaiting retest
  • Guided bromine care, including oxidation shock when needed
  • Optional balancing targets and clearer dose-unit conversions

Water balance & CSI

Pooli includes a Calcite Saturation Index (CSI) calculator for scale and etch tendency on plaster and related surfaces. Pooli implements a practical pool-water saturation index derived from established LSI/CSI methodology and adapted for swimming pool water chemistry.

  • Primary CSI guidance with optional conventional LSI for comparison
  • Lookback for missing CSI inputs from prior tests
  • Optional magnesium and TDS when available; salt as dissolved-solids proxy when TDS is not
  • Input confidence when values are measured, looked back, estimated, or defaulted

Inventory, feeders & equipment

  • Shed inventory with low-stock alerts and usage history
  • Catalog vs custom products, SpinDisk / strip auto-deduction
  • Chlorine or bromine feeder tracking with history and sanitizer overlays
  • Filter pressure baselines and maintenance overlays
  • SWG and equipment charts with selectable time ranges
  • Custom product reminders with multiple schedules and strengths

Offline, sync & smarter assistance

  • On-device database for pools, reminders, inventory, and logs; sync when you reconnect
  • Percy AI follow-ups on algae & cloudiness and weather impact reports
  • CYA lookback for chlorine targets when Auto-adjust for CYA is enabled
  • Ask Pooli community forum and Pool Club benefits for members

Built-in calculators

  • Total & free chlorine
  • pH & total alkalinity (including adjusted alkalinity)
  • Cyanuric acid & stabilizer guidance
  • Calcite Saturation Index (CSI)
  • Volume, dose, and other pool math tools

What pool owners are saying

"TBH, this app has made the stress and confusion of maintaining a pool for the first time - a non issue. A legit 5*s!"

- SNARE, First-Time Owner

"I am a mom of 4 kids, not a professional. This has SAVED me! I tell every pool owner I meet about this app and how I love that it has enough free features so I don't have to spend MORE $ on the pool!!"

- phantom365ak47, Family Pool Owner

"Great app to keep you on top of your tasks. We let go of our pool company who only came once every two weeks and was just overdosing our pool with chlorine to keep it clear. Using Pooli, we've got our water easily balanced."

- Kelly, Pool Owner

"I have been the owner of a hot tub for about seven years now. I found this app, loaded it and was pretty amazed at how easy it is to use. I was able to balance my water perfectly with a few chemicals I had."

- Runner 1979, Hot Tub Owner

"It's well developed, easy to use, never crashes, it gives perfect suggestions for how much chem to add to my pool, you implement suggestions quickly, respond quickly, and that's all well worth it to me."

- Chris, Pool Owner

"Sanity Saver!!! I use a titration test bc I feel like there is too much error in strip test scanning. I LOVE that it allows me to customize what tests and what brand products I use."

- SaHoppa, Pool Owner
