Original release notes

A volume that cannot be right is caught
Every amount this app gives you is sized from your pool's volume, so a number that is out by one digit is out everywhere. Whether you type it, work it out from your dimensions, or trace it on the satellite view, an impossible volume is now refused and an unusual one is questioned before you continue.

The satellite trace opens on the address you typed
The map now asks for your street address rather than settling for a nearby place, so the trace starts on your house instead of a park down the road. The review screen shows the pool you traced, not the middle of your postcode, and when only an approximate location can be found the app says so instead of pretending.

One screen between signing up and a blank form
Creating an account used to land you on an empty address form with nothing said. It now opens on a short screen naming what setup involves, roughly how long it takes, and that everything is unlocked for two weeks with no card.

What to look for on the shelf
A recommendation names the exact chemical. Now the card also tells you what that chemical is called on a shelf, the strengths printed on labels, the sizes it comes in, and what you can safely use instead. Strength is the thing to check: two jugs can look identical and one can be twice the other.

A big dose reads differently from a small one
A correction you should pour in one go, split across a couple of hours, or stage across several visits now says which. Every amount used to carry the same tone whether it was a cup or five gallons.

The shock card reads what you logged
Logging a shock-level dose through the plan now updates the shock card. The app stops telling you a shock is due when you did it an hour ago.

Swim-safe without hunting for a chart
The line about retesting before you swim now prints the actual chlorine range for your pool instead of pointing at a card that is not always on the screen.

Sign-up stops flagging what you already fixed
Correct a sign-up field and the complaint about it goes away, instead of sitting there until you submit again.

Home agrees with your checklist
Home no longer says there is nothing to do today while your checklist still has items waiting on it.
