I have apple watch series 4 and an iPhone. I want to send data like links,images,text to my watch. Usually I emailed these data to myself and open it on my watch .
Is there any efficient way to do it ?
Any app or something ?
My watch is constantly connected with iPhone via Bluetooth.
Apple Watch connects to Wi-Fi networks it has connected whilst being linked via Bluetooth with your iPhone. See: About Bluetooth and Wi-Fi on Apple Watch
So, let's say you forget your phone at home but you're wearing your watch at work. Your watch will recognize the wifi network and still give you your notifications over Wi-Fi.
You might also need to mirror notifications. See: About notifications on your Apple Watch
I went for a 2:30:00 run yesterday with my iPhone (6s) in my bag and my watch running strava. VO2max was recorded once per hour in three hours (10-11/11-12/12-13). I’ve tried to get VO2max off of shorter runs (5k-10k) on the same route without my phone but no data. I will now have to test longer runs with just watch and shorter ones with phone to get a definitive answer. Hope this is helpful.

A simpler method would be to use Messages to send a message to yourself with the text, links, and images. They would show up as notifications on the watch making it easy to tap into them - instead of having to open up Mail, find the right mail, open attachment, etc.
