Best Smart Pet Water Fountains for iPhone (2026)

As an Amazon Associate we earn from qualifying purchases.

Quick answer: A smart pet fountain encourages dogs and cats to drink more (flowing water is more appealing) and alerts your iPhone when water or filters run low. Get a stainless-steel fountain for hygiene, a large-capacity one for multiple pets, or a wireless-pump model for quiet operation. Easy cleaning, filter cost, and low-water alerts are what matter most.

Pro tip — stainless or ceramic is easier to keep clean than plastic, and factor ongoing filter cost. Plastic fountains can harbor bacteria and cause feline acne; stainless steel or ceramic is more hygienic and easier to scrub. The real long-term cost is replacement filters — check how often they're needed and the price. Disassemble and deep-clean the pump regularly so flow (and your pet's interest) doesn't drop off.

📦 iPhone App or Wi-Fi Trouble?
