Usually smart watches are used in tandem with smartphones. The watch is paired with smartphone using bluetooth connection sou you could see all phone activity on your wrist. Probably this is why in many cases smart watch is considered to be unnecessary gadget. You have to have to carry both devices instead of one. If you have phone, why would you want to duplicate functionality on your watch.
We all know that smartphone is more convenient in many ways starting with screen size, processing power and habit of using it as a phone. But with smartphone there is always one more action to take before using it. It is always somewhere in the pocket, purse or on the table. You need to pull it out before using while smart-watch phone can be always on your wrist. If you like this way of thinking then you should consider purchasing a smart watch phone instead of smartphone. Of course there is always an option to have them both and get most of it.
When speech comes to smart watches the big factor is a price. They always tend to be quite expensive. This might be true if you are chasing for big brands. They are always overpriced but cannot offer something more what cheaper models does. There is actually lots of to choose from. Lets look at decent smart watch phone Rthyn L6 that can be found on GearBest for about $46.
It could be used as stand alone phone or in tandem with your smartphone. The watch will only work with GSM networks: GSM 900/1800MHz and is unlocked for Worldwide use. It has a slot for micro SIM that allows hawing phone functions on your wrist. The smart watch is powered by MTK2502 CPU along with 64MB of RAM and 128MB of ROM. Memory can be expanded with TF card up to 16GB.
The only disadvantage by using smart watch instead of smart phone is screen size. The watch comes with 1.22 inch IPS screen with resolution 240×240. But don’t forget this is a smart watch so things has to be a bit tight. There is also no camera on the watch. And I don’t know if you would want it here, unless you like geeky stuff. But you have ability to trigger smartphone camera remotely via bluetooth. Other functions like alarm, pedometer, mp3, mp4, sleep monitoring and other are built in. Smart watch is also waterproof in case you like to go a bit extreme with it.
