One glance,
one answer.
The home screen answers exactly one question — is it ready? — and gets out of the way. Temperature, target, pH and sanitiser, all live, all before you've unlocked your phone at the door.
The ring itself tells the story: cool teal climbing to warm ember as the water approaches your setpoint, so the state reads before the number does.
Every pump,
on its own.
Most spa apps give you one button: everything on. MySpaSimple gives you five — each pump switched individually, from your phone or straight off your wrist, because "easy mode" isn't always what you want.
Your tub's actual layout, not a generic one: this app knows a five-pump swim spa looks nothing like a two-pump lounger, and adjusts — blowers included only if you actually have them.
A band,
not a number.
7.42 means nothing at a glance. A dot sitting calmly in the middle of a green band does. MySpaSimple reads pH and ORP the way you actually decide whether to get in — low, OK, or high — and explains what each figure is measuring, in plain language.
Alerts wait for a reading to persist before they bother you. Bathing causes short swings; the app doesn't cry wolf over one of them.
2026,
not 1986.
Every hot tub control panel since the Reagan administration has looked the same: beige buttons, seven-segment digits, a manual you've lost. Tub mode is the poolside screen you actually want to touch — big glowing pads, one thumb, in the dark, without your glasses.
Jets, lights and setpoint, all reachable one-handed, lit from within so it reads before it's even in focus.
Paste one key.
That's it.
No account to create in-app. No password to lose. Sign in once at myarcticspa.com, generate a key, paste it — and the app never asks again, because there's no session sitting around to expire.
Your Apple Watch doesn't even get its own setup screen: the phone hands the key across automatically, over an on-device connection that never touches the network.
