Pool water volume plus exact chlorine, pH, alkalinity and salt dosing.
Build a step-by-step balancing plan. Private by design — your data stays in your own iCloud, never…
Stop guessing how much chlorine, acid, or salt your pool needs.
PoolDose does the water chemistry math for you — 100% offline.
WHAT YOU CAN DO
• FIND YOUR POOL VOLUME
Enter your pool's shape and dimensions — rectangle, round, oval, kidney,
or L-shape — and get an accurate water volume in gallons or liters.
• GET EXACT DOSING AMOUNTS
Enter your current test readings and PoolDose tells you precisely how much
chlorine, pH up or down, alkalinity increaser, calcium, stabilizer, or salt
to add. Pick your exact product strength for accurate results.
• FIX YOUR POOL IN ORDER
One screen, all your readings in — PoolDose builds a step-by-step balancing
plan in the correct order, so you never chase your own adjustments.
• CHECK WATER BALANCE
See your LSI and CSI saturation index instantly and know whether your water
is corrosive, balanced, or scaling — before it damages surfaces or equipment.
• TRACK EVERY POOL
Log test results over time, watch trends on clear charts, and manage as many
pools or spas as you like.
• SIZE YOUR EQUIPMENT
Calculate turnover rate, flow rate, pump run time, filter size, and heater
warm-up time.
PRIVACY FIRST
PoolDose runs entirely on your iPhone. No account, no sign-up, no analytics,
no ads, no data collection. Your pool data never leaves your device.
