I had the exact same frustration — those apps either want too many permissions or are flooded with pop-ups. Recently, I started using
Snapinsta, and it’s been smooth sailing. You can open it right in your phone’s browser, paste the Instagram post link, and download the video or image instantly. It works with reels, stories, and carousel posts too. What’s great is you don’t need to log in or deal with any extra steps. I’ve been using it almost daily to save inspirational content, and it hasn’t failed me yet.
