This Reddit Image Downloader app allows you to do a search for any images on any subreddit and save them to their device's gallery! It's quiet simple: just make a search for any subreddit you'd like that you know has images on it and you'll be given all the images found on that category and/or page.
You can then download the images one-by-one or utilize the 'Save All' feature which downloads all fetched images at once.
Absolutely no ads on this app so you can view and download images on Reddit without any hassle or interruptions.
