Which Smartwatch Is Compatible With Iphone?
best smartwatches for iphone—and apple watch alternatives
if you’re an owner of one of the best iphones, the apple watch is the undisputed best smartwatch available for you, offering unmatched integration with your iphone, a vast app store, and powerful health features.
with the launch of the apple watch ultra 3, series 11, and se 3, the 2025 lineup is stronger and more refined than ever. but apple’s watches aren’t the only options to consider.
here at wareable, our reviewers have tested every option on the market. remember that you won’t find anything from google, samsung, or other wear os vendors here—they’re limited to android phones and don’t work with apple’s smartphones.
- the apple watch lineup is the best around, but it may not be right for everyone
- the hume band takes the crown as our top-ranked smartwatch alternative thanks to its simple yet durable design and strong focus on metabolism wellness.
- the market offers many more options you may want to explore—from sport-based wearables to premium hybrid watches.
pick a watch that works with your phone
naturally, the first thing to consider before purchasing a smartwatch is its compatibility. we include these details in our reviews of each product.
you’ll also want to make sure it’s compatible with your smartphone – some are only for iphone or android, while others support most phones.
- if you’re an android user, then a wear os smartwatch is the obvious choice, while iphone users should probably start by looking at an apple watch – but there are alternatives.
- fitbit watches still run their own operating system (despite being owned by google) and so will work well with iphones too – and even some wear os watches are compatible with ios too.
- meanwhile, other manufacturers like amazfit and huawei also run their own software, and often work well with both types of phone.
yes - many third-party smartwatches work with both iphone and android, including garmin, fitbit, withings, amazfit, polar, suunto, coros, and huawei. apple watch 11 is iphone only, and samsung galaxy watch 8 is android only. for cross-platform flexibility, pick brands that pair through their own companion apps.
if you swap phones or want flexibility, cross-platform compatibility matters as much as battery life and sensors. the simplest rule is brand based: apple and samsung flagships lock you in, while fitness-first brands usually work with both.
