Best Smartwatches Under $100

Smartwatches used to be pricey gadgets for tech geeks, but this has changed. These days, you’ve got plenty of solid smartwatches for under $100.

They track your steps, monitor your heart rate, buzz your wrist with notifications, and even run a few basic apps. Sure, they’re not going to outshine an Apple Watch or Galaxy Watch, but honestly, most folks don’t need all those fancy extras anyway. Affordable smartwatches have gotten way better, and for a lot of people, they do everything you actually want from a smartwatch.

If you’re hunting for the best smartwatch under $100, I’ve got you covered. This guide breaks them down by battery life, health features, build, and how easy they are to use—so you can pick one that works for your daily life without blowing your budget.

What to Expect From a Smartwatch Under $100 ?

Before we get into the actual watches, let’s be real about what you can expect for the price. Most budget smartwatches cover the basics:

• Step counting and activity tracking
• Heart rate monitoring
• Sleep tracking
• Phone notifications (calls, texts, apps)
• Multi-day battery life (not just a day or two)

But you usually won’t find:

• App stores like Apple’s or Google’s
• Medical-grade health features (like ECG or blood pressure)
• Fancy stuff like sapphire glass or stainless steel

Honestly, that’s not a bad trade-off. A lot of people actually like that these watches stick to the essentials and don’t need a charge every single night.
