Pool Chemical Calc - PoolDo...
Enter readings, get the dose
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Enter your test kit numbers and every chemical you need appears with its dose on one screen. The maths is shown, so you can check it. Log as many tests as you like.
PoolDoseLog logs your pool and hot tub water tests and works out how much of each chemical to add. Enter the free chlorine, combined chlorine, pH, total alkalinity, calcium hardness, stabiliser and water temperature from your test kit or strips, and every dose you need appears on one screen.
The maths is shown too. Water volume, the gap to your target, the strength of your product and the rounding are all laid out, so you never have to take a number on trust.
Target ranges come as Standard, TFP style or Manufacturer, and every single value can be changed. Chlorine, bromine and salt water (SWG) pools are all supported, and outdoor pools have the effect of stabiliser folded into the calculation. Hot tubs are supported as well.
Enter your water volume directly, or work it out from rectangle, round, oval or freeform dimensions. Your own products go in too, down to the strength of your liquid chlorine and which acid you use.
Everything you add is kept in a dosing log, and your readings are plotted on a chart. Reminders can be set for water tests, filter cleaning, backwashing and salt cell cleaning.
Records are stored on your device and backed up automatically once a week. You can also send a copy off the device as a zip file and restore from it. Tests and doses export to CSV, and tests can be imported from CSV.
There is no cap on how many tests you can log. Units switch between gallons, ounces and Fahrenheit or litres, grams and Celsius.
