You can customize your Apple Watch in countless ways with the best Apple Watch complications. With custom complications, for example, you can view upcoming flights or hotels, your next pill dosage, whether it's going to rain in a half-hour, how long you've been working out, and much more from your display.  

There are hundreds (perhaps thousands) of third-party complications you can install on your Apple Watch. Here are some of our favorites.

I've been writing about Apple since 2010 with a brief hiatus to work at the Apple Store. I'm an Apple Watch enthusiast who was once the sole writer for an Apple Watch website. I use those complications on my Apple Watch face (and other Apple Watch features) multiple times per day.

Calendar by Fantastical

Not only is Fantastical an excellent calendar app for your iPhone, iPad, and Mac, it also supports your Apple Watch and offers one of the best Apple Watch complications. While the watch app gives you a quick rundown of everything on your calendar for the next few days and lets you add new events with your voice, the Fantastical complication displays your next (or current) appointment, along with either a time frame or an "UNTIL" indicator letting you know when your meeting's ending. It also supports Time Travel, letting you fast forward through the day's events.

CARROT Weather

For a snarky take on today's weather, you can't go wrong with Carrot. One of the most popular weather apps on the App Store, Carrot doesn't come cheap, however. To get Carrot Weather complications on your Apple Watch, you'll need to purchase a premium plan, which is currently $4.99 per month or $19.99 per year. 

Carrot Weather provides numerous complications that vary by the Apple Watch face. These complications can list the weather in icon form, what the temperature feels like, the highs and lows of the day, and a quick notation on what the sky's doing—"cloudy later on," "rain in three minutes," and the like. 

You can download Carrot Weather free and get one of the best complications for Apple Watch to track your local weather. The freebie version will work on iPhone. Use an in-app purchase to upgrade your membership. You can also turn off the snark feature if you don't like being called "meatbag," for example.

Streaks

Streaks is one of the best habit tracking apps for iPhone or iPad—whether it's walking the dog, doing yoga, standing for a certain amount of the day, or more. (It even integrates with the Apple Watch and the Health app to track certain tasks automatically.)

The app's complication is one of the simplest I've seen—it's only available in small size and displays as a series of light and dark dots—but it's surprisingly useful. White dots mean you've completed your task for the day; gray dots nag you to finish on up. If you like motivating complications, Streaks might just be your ticket to greatness. They say that the best time to start a good habit is yesterday; the second best time is today. Streaks is one of the best Apple Watch complications to help you get started on your good habits right now.

Streaks is currently priced at $4.99 on the App Store. It's available for iPhone, iPad, Apple Watch, and Mac.

Offering a wide selection of highly customizable complications, the freemium Watchsmith is unique in that it's time-based.
