It has a very easy to use app, and very easy to set up, takes no more than 5 minutes to set up, not including the time it takes for the watch itself update. It looks great and functions great. You can add nice wallpapers to the background and change how the watch face looks, with different colors and styles. It does a great job at counting steps and keeping track of exercises. Even if you don't tell the watch your about to exercise it will automatically detect that you are doing one and start tracking calories burned, steps taken, and more!
Even if you don't have a Samsung phone it still will work with any android phone for the most part. I no longer have a Samsung phone from when I bought this watch, but I still continue to the watch with my Google Pixel 7a.
The only thing about the watch that isn't the greatest is the battery life. This watch will last one day, that's all. Luckily it is easy to charge as it just uses a included wireless charger, so you won't have to plug the watch in.
Overall an amazing watch packed with great features for a great price. If your looking for a watch that isn't going to break the bank but also isn't complete garbage than this is what your looking for!

Bought Galaxy Watch 4 as a replacement.
The first watch had a minor paint imperfection on the watch case. I thought it was small, but once I saw it, I couldn't unsee it. After trying to live with it for a few days, eventually I decided to exchange it through Amazon.
The second one had a broken SpO2 sensor. During sleep, it would show that my SpO2 levels dropped to dangerously low levels (below 85%) almost every night (I tried for 7 nights). I know this was not normal because the first watch didn't have this problem. Ended up returning the second one to Amazon.
I got tired of waiting for shipping and returning items, so I went to pick one up from a local Costco store. The third one had a mushy power button that was not clicky. It also had erratic sleep tracking--two nights in a row, I slept for about 8 hours and it showed only about 4 hours. Its heart rate sensor also did not match my fingertip oximeter. Ended up returning the third one as well.
Got a fourth one from Costco, and it's finally problem free.
Love the watch so far, but the quality control was not great--I shouldn't need to go through 4 watches to get a satisfactory one.
All four watches had different levels of clickyness with their buttons, but I guess people wouldn't know unless they tried multiple ones. This shows their product inconsistencies.
----------
Short product review:
Sleep tracking seems really accurate if the watch is not defective. Three out of the four watches had really accurate sleep tracking. Based on my experience, the watch can also track naps, but they need to be long enough (like longer than 1 hour.)
Heart rate tracking was extremely accurate by comparing to my fingertip oximeter (when not defective.) The one that had bad sleep tracking also had a bad heart rate tracker.
SpO2 tracking was completely off on one of the four watches. The other three seemed to do a good job: I compared to my fingertip oximeter and the error is less than <2% with the watch usually showing a slightly lower number.
WearOS was great--can download GooglePay, Spotify, and GBoard from the Play store. Can also use watch faces from the Play store.
Mobile App sometimes causes battery drain. I don't know what triggers it. Once I see fast battery drain, restarting my phone fixes it.
Overall, I would give the watch 4 stars, but the buying experience was only 2 stars. If I didn't have access to great stores like Amazon and Costco with great return policies, I wouldn't gamble my luck with this watch.
I have an Aura Scales which syncs to my Samsung Health and smartwatch. It also has the weather forecast. I can read my text messages and add apps to my watch. I can make and receive calls.
The only drawback is battery life. I have to charge it every day. I charge it while eating lunch.
