Dip a test strip and snap a photo. AI reads every pad for you in about ten seconds, then builds a treatment plan for your exact tub — what to add, how much, and in what order.
Two free tests every day. No account needed.
No more squinting at a colour chart in bad light, then wondering how much to add.
Any standard hot tub or spa test strip. Nothing proprietary to buy.
Photograph the strip and AI matches every pad to a number in about ten seconds.
Exact products, the right order, and how long to wait between each one.
The AI works every dose out from your tub's volume and sanitiser — not generic advice copied off the back of a bottle.
AI readings at a glance
Your AI treatment plan
Tracked over time
Two models, each doing a different job.
Vision AI matches the colour of every pad on your strip to a value, coping with the lighting, angle and shadows that make a colour chart so hard to read by eye.
A second model takes those numbers with your tub's volume and sanitiser type, and writes the plan — which product, what change it makes, and how long to wait.
It works to spa chemistry, not pool chemistry: alkalinity before pH before sanitiser, proper spa ranges, and never two chemicals at once.
Every day, forever. No account, no card.
