Enter your water test results and Simple Pool tells you exactly how much of each
chemical to add, calculated for your pool's volume, surface and sanitizer. No
spreadsheets, no pool store trip, no pool math.

A POOL TEST LOG THAT ACTUALLY HELPS
Record free chlorine, combined chlorine, pH, total alkalinity, calcium hardness,
cyanuric acid (CYA), salt, bromine and water temperature. Every reading is
colour-coded against the ideal range for your pool, so you can see what is off at
a glance.

EXACT DOSING, IN YOUR UNITS
Get a clear instruction like "Add 77 fl oz of 10% liquid chlorine" instead of a
vague target. Doses come from your pool volume and switch between US and metric
units. Tap any recommendation for step-by-step directions, safety notes and what
to expect afterwards.

BUILT AROUND YOUR POOL
- Chlorine pools: free chlorine targets that follow your CYA level
- Saltwater pools: higher CYA targets, salt tracking and salt generator output
guidance
- Bromine pools and spas: lower pH targets, no CYA needed
- Plaster, vinyl and fiberglass each get their own calcium hardness ranges

WATER BALANCE
See your CSI (Calcite Saturation Index) at a glance and catch scaling or etching
before it damages plaster and equipment.

SHOCK TREATMENT
Fighting pool algae? Shock mode raises and holds free chlorine at the shock level
for your CYA, tracking each test until the water clears and combined chlorine is
gone.
