Thank you.

I use https://imgplay.net/index.html to make GIFs on my iPhone. They also have an Android app.

If you want to make gifs on your Apple computer then I recommend https://giphy.com/apps/giphycapture.
I don’t use windows, so I cannot say for that operating system.

Super ....... thank you. I will download Iphone app today itself. Then soon can post a gif.
