HI!!! this isn't probably the right place but not sure where else to ask. I am in the US and would like to have an android watch that has android apps & health apps I suppose.
I don't want to have my note 8 in hand all the time & it would be easier to have and respond to some notifications when the phone is away somewhere.
Oh & I am a female

.
Can someone guide me please

thanks all!
Ok, almost every smartwatch right now does the things you need, Health app and heart monitor, answer notifications and answer calls (paired with your phone), own apps.
Now, there are 3 major OS you can choose, android wear (wear OS), tizen and Apple watch.
Wear OS is not limited to one company, there are a lot of companies using it, like Huawei, LG, Fossil, Motorola, etc, the watches are highly compatible with any android phone and a lot of apps and faces (styles for your watch).
Tizen is the samsung exclusive OS for their smartwatch, is compatible with any android and iphone BUT only on Samsung phones you can have the full experience. Tizen has its own store and as Wear OS you can download apps, faces and use it as any other watch.
Apple Watch, compatible with iPhone and android BUT, only on iPhone you have all features.
GOOD.
Wear OS. Lots of companies with a wide choice, lots of apps and faces. You can use it with any android phone
Tizen. Great design for the OS, the bezel to navigate throw menus nobody has it, lot of apps (not as much as wear OS), faces. Can use it with any android phone but only on samsung you have the full experience, and is great.
Apple watch. lots of apps and support. and I dont know, I havent use any... sorry
CONS.
Wear OS, the battery life really sucks almost on all the model, One day TWO tops.
Tizen. Great battery life, minimum 3 days and 5-6 tops, the OS has been updating frequently, for example, the gear S3...
Apple watch, expensive, noy fully compatible with android
Personal opinion.
I've using Gear S3 from one year now and the battery life is great, 3-4 days using it every day to track my running, not using to sleep. All notifications on all the time, answering calls, etc etc and the best part is that I have it paired with my note 8 and I received two major updates. Is not expensive and also is the "woman" version, which is smaller and gold color.
