TubNudge: Hot Tub & Spa Care

TubNudge is a hot tub and spa maintenance app. It keeps your water care on schedule and reminds you when something is due, so the water stays clean and you never have to remember when you last rinsed the filter. It is also a water test log: write down what your test strip showed and see at a glance whether pH, alkalinity and sanitizer are in range. Tell it which hot tub you have and how you sanitize it: chlorine, bromine, salt water, or Frog @ease. TubNudge builds a maintenance schedule for your spa and sends one reminder a day, only when a task is due: testing the water, rinsing and replacing filters, draining and refilling, cleaning the cover, and more. WHAT YOU GET, FREE • A hot tub maintenance schedule made for your model. Pick from 172 hot tubs and spas from 20 brands, or enter the details yourself. • Reminders at the time you choose. Mark a task done or push it to tomorrow right from the notification. • A clear Today screen: what needs attention, what you did today, and what's coming up. • Water test log. After you test the water, tap what your strip shows: pH, total alkalinity, chlorine or bromine, hardness, stabilizer, salt. Works with test strips, color-only pads, drop kits and digital testers. Each reading is marked in range, low or high. • Soak timer. Start it when you get in, get a gentle chime when time is up, and the soak is logged for you. • Soak log and water age. See how much the tub is used and how long since the last drain and refill. • Your own tasks. Add anything your spa needs and set how often. • Intervals you control. Match your owner's manual, or switch a task off. • Maintenance history with notes and your water test readings, so you know what was done and when. • Checklists for winterizing, start-up, and going away. • Works offline. No account needed and no ads. • Optional free backup. Sign in with Google to restore your hot tub's history on a new phone.

A NOTE ON CHEMICALS TubNudge reminds you when to do things and keeps a record of your water test readings. It does not read test strips for you, and it does not tell you how much of any chemical to add. Always follow the label on your product and your hot tub's owner's manual.
