Stay Comfortable at Home — Without the Hassle.

At Keystone, we believe everyone deserves a comfortable home without breaking the bank. That's why we built the Keystone app: a simple, no-fuss way to control your home appliances from the palm of your hand. Whether you're cooling down a bedroom, managing humidity, or setting a sleep timer before bed, everything you need is right here.

Easy Setup, Every Time
Getting started is a breeze. Use QR code pairing to connect your appliances quickly — no complicated steps, no head-scratching. Once your device is paired, the app walks you through Wi-Fi setup so your unit is connected and ready to go in minutes. You can even log in with face recognition for fast, secure access every time you open the app.

Total Control, Right From Your Phone
Once you're set up, you're in complete control. Adjust your settings to match exactly how you like it:
• Power — Turn your unit on or off from anywhere
• Temperature — Set your ideal comfort level with precision
• Mode — Choose from Auto, Cool, Dry, Fan, or Heat (where applicable)
• Fan Speed — Find the right airflow for any moment
• Precision Airflow — Direct airflow exactly where you want it
• Eco Mode — Save energy without sacrificing comfort
• Sleep Mode — Quiet, gradual adjustments for a restful night
• Timer — Schedule your appliances to fit your routine

Manage Your Home, Your Way
The Keystone app makes it easy to stay organized, no matter how many devices you have. Name your appliances so you always know which unit is which — ""Living Room AC,"" ""Basement Dehumidifier,"" whatever works for you. Group and filter devices for quick access, and share device access with family members so everyone at home stays comfortable. Need a hand? Our built-in Help Center is always just a tap away, with straightforward answers to get you back on track fast.

Built for Real Life
We know your time is valuable and your budget matters. Keystone products are designed to deliver high performance at a price that makes sense — and this app is no different. It's straightforward to use, thoughtfully designed, and built to make your day-to-day life a little easier. With thousands of happy customers and top ratings across our product line, Keystone is the brand your neighbors trust — and now it's even easier to see why.
