Best Smartwatch Under $100 (October 2026)

The hardware is solved. The software is the risk.

A $90 smartwatch in 2026 has an AMOLED display you can read in sunlight, an optical heart-rate sensor, blood oxygen measurement, sleep staging, GPS on many models and battery life measured in weeks rather than days. On raw hardware it is a remarkable amount of device for the money, and it comfortably outlasts a premium smartwatch between charges.

The risk is entirely on the other side. A smartwatch is useless without its companion app, and budget brands have a poor record of maintaining apps once a model stops selling. When the app stops being updated, a phone OS upgrade eventually breaks it, and the watch becomes a watch.

So the single most useful thing you can do before buying is look at the companion app's update history in the app store. A brand pushing updates every few weeks across several years is a brand that will still be there. One whose last update was fourteen months ago is a warning, regardless of how good the hardware looks.

Decide what the watch is actually for

Budget smartwatches do three different jobs and are usually bought by people who have not decided which one they want.

Notifications and a watch face. If the goal is to see who is calling without taking your phone out, almost any model here does it well, and battery life should be the deciding factor.

Fitness tracking. If you want accurate pace and distance for running or cycling, you need built-in GPS, not connected GPS that borrows the phone's. That is the single spec that separates a useful training watch from a step counter at this price.

Health monitoring. Budget watches measure heart rate reliably at rest and less reliably during high-intensity exercise. Blood oxygen and stress readings should be treated as trends rather than numbers, and no watch at this price is a medical device. We would not buy one for health monitoring specifically.

• Built-in GPS is the spec that matters for running and cycling.
• Check the app's update history before you buy anything here.
• AMOLED displays are now standard - a TFT screen at this price is a reason to look elsewhere.

If you want a watch rather than a screen

Worth saying plainly: a smartwatch and a watch are different purchases, and plenty of people buying a budget smartwatch actually want a watch that looks good and tells the time well.

If that is you, the best watches under $100 is the more useful page. A mechanical or quartz watch at this price will look better, last decades, and never need an app. The smartwatch is the right answer only if you genuinely want the notifications and the tracking.

When to spend more

Two reasons, and both are specific.

Serious training. If you follow structured workouts, want accurate recovery metrics or need multi-band GPS for trail running, a dedicated sports watch is a genuinely different instrument and the budget tier cannot substitute for it.

Ecosystem integration. An Apple Watch with an iPhone, or a Pixel Watch with Android, does things no third-party watch can - unlocking devices, responding to messages properly, contactless payments that reliably work. If that integration is the point, buying a cheaper watch does not get you a cheaper version of it; it gets you a different product.

Otherwise the hardware here is genuinely sufficient. Our cheap smartwatch buying guide goes deeper on the app-support question specifically.
