How it works
Test the water your way
Dip a test strip and the app times it and takes the photo. Or photograph the pool shop printout or open the PDF they emailed. No strips yet? Start with what you know about your pool.
Get a plan for your bottles
Tell it the products you have: liquid chlorine 12.5%, pool acid 32%, any brand. You get each dose in litres, cups or spoons, one product at a time, in the order that works.
Swim when it's safe
Tick each step as you go. The app counts down the waits and tells you the time you can swim, then reminds you when to test again.
Green water, back to clear
- Drain or treat? Small inflatable pools, no filter or very high stabiliser: draining is faster. The app tells you which.
- Get the pH right first, brush the walls and run the filter all day and night.
- Shock to the level your stabiliser needs and keep it there. You get the exact amount for your bottle.
- Test morning and evening. It's done when the water is clear and loses less than 1 ppm overnight.
Wherever you're starting from
- Just filled a new pool
- A shopping list for your pool's size and a day-by-day start-up plan, even before you own test strips.
- The water went green or cloudy
- Drain or treat? The app answers that first, then walks you through shocking it until it holds clear overnight.
- Weekly care
- Two tests a week, a plan after each, reminders for the filter and the salt cell. Ten minutes instead of a trip to the shop.
- A hot tub
- Smaller doses measured in spoons, and when to change the water based on how many people use it.
A second opinion that isn't selling you anything
Pool shops test for free because they sell the chemicals. A pool service is typically $100–$300 a month in Australia. Lido Pool only does the maths.
| Pool shop test | Pool service | Lido Pool | |
|---|---|---|---|
| Doses for the products you already own | Their brand | Their products | Any brand |
| Amounts you can measure at home | Kilograms per bag | Done for you | Cups, spoons, litres |
| When you can swim | Ask at the counter | Ask the technician | A time, with a reminder |
| Cost | Free, plus what you buy | $100–$300 a month | Free 7 days, then a small yearly plan |
Work out what a pool service costs you against doing it yourself.
Free calculators, no sign-up
Questions
Does it work with the brand I buy?
Yes. You enter what's on the label (for example liquid chlorine 12.5% or pool acid 32%) or photograph the label and the app reads it. Doses are worked out from the strength, not from a brand.
Do I need test strips?
For a new pool you can start without them: the first item on your shopping list is a pack of strips. After that, strips, a drop test kit or a pool shop printout all work.
Are my photos or test results uploaded?
No. Photos and PDFs are read on your iPhone and not kept. Your pool details and test history stay on your phone. There is no account. See the privacy policy.
When is the app out, and what does it cost?
The iPhone app is coming in December 2026. Everything is free for the first 7 days, with no card. After that the calculators and your test results stay free, and the plan after every test, reminders and swim times are part of a small yearly subscription.
