The short answer: tap the search icon at the bottom of the Reddit app, type a topic, then filter by “Communities.” That’s the fastest way to find any subreddit.
But the Reddit app hides subreddits in a few places that aren’t obvious at first glance. Unlike the desktop version, where you can scroll a huge list of communities, the mobile app relies heavily on search and browse menus. If you don’t know where to tap, you might miss half the subreddits that actually match your interest.
Here’s how to find subreddits on the Reddit app without frustration.
Step 1: Use the search bar like a local
Open the app and tap the magnifying glass icon at the bottom. Type your topic—for example, “photography,” “startups,” or “marketing.” You’ll see a list of results. Look at the top of the results screen for tabs: “Posts,” “Communities,” “People,” and sometimes “More.” Tap “Communities” to see only subreddits.
Most beginners skip the filter and scroll through posts instead. That wastes time. The “Communities” tab shows you exactly what you need.
To narrow further, add a second word. Searching “photography beginner” instead of just “photography” will surface smaller, more focused subreddits like r/BeginnerPhotoCritique instead of the massive r/photography.
Step 2: Browse by category (the hidden menu)
The Reddit app has a browse menu that most people ignore. On the home screen, tap your profile icon (top left) or the Reddit logo at the top. You’ll see a list of categories like “Gaming,” “Sports,” “News,” “Technology,” and “Business.”
Tap any category to see a curated list of popular subreddits in that niche. This is useful when you don’t have a specific topic in mind yet. For example, if you tap “Technology,” you’ll find subreddits like r/techsupport, r/gadgets, and r/programming.
This method works well for discovering niche subreddits you didn’t know existed. The categories are broad, but they surface communities that might not show up in a simple search.
Step 3: Check “Similar Communities” inside any subreddit
Once you’re inside a subreddit, scroll to the top. Below the subreddit name, you’ll see a row of icons and a “See more” link. Tap “See more” to open the “About” section. Scroll down, and you’ll often find a list of related subreddits.
For example, if you join r/marketing, the “Related communities” section might list r/smallbusiness, r/content_marketing, and r/SEO. This is a goldmine for finding **business subreddits ** that are connected to your main interest.
This is one of the most underused features in the app. Most people never scroll past the first few posts, so they miss these links entirely.
Step 4: Save and organize the subreddits you find
When you find a subreddit you like, tap the three dots next to the “Join” button. Select “Add to Favorites” or “Add to Custom Feed.” Custom feeds let you group subreddits by theme—for example, a feed for “Marketing” with five different subreddits in it.
This keeps your home feed clean and helps you check specific topics without scrolling through everything.
Common mistakes beginners make on the app
- Searching only one word. If you search “design,” you get r/design, but also r/graphic_design, r/DesignJobs, and r/DesignThinking. Add a second word to get exactly what you want.
- Ignoring the “Communities” filter. Without it, you see posts, not subreddits. That’s a common frustration.
- Joining a subreddit without checking subreddit rules first. Tap “See more” at the top of any subreddit to read the rules and requirements. Many subreddits block posts from accounts without enough comment karma or account age.
- Forgetting to check **subreddit requirements ** before posting. Some subreddits require a minimum karma or a verified email. Check the “About” section to avoid getting your post removed.
Quick checklist before you join a new subreddit
- Read the subreddit rules in the “About” section.
- Check the “Subreddit quality check ” by looking at recent posts—are there real discussions or just spam?
- Note any karma or account age requirements.
- Browse the top posts of the month to understand the tone.
- Add the subreddit to a custom feed if you plan to follow it long-term.
Practical takeaway
The Reddit app is not as open as the desktop site, but it’s faster once you know the taps. Use search with the “Communities” filter, browse categories, and check the “Similar Communities” section in every subreddit you join. That’s the fastest way to find subreddits on the Reddit app without clicking through dozens of irrelevant posts.
If you’re researching a niche or building an outreach workflow, start with these three methods. They’ll save you time and help you find active subreddits that actually match your goals.
For this use case, practical proxy option for Reddit workflows should be compared by pricing, setup difficulty, support quality, refund policy, and whether it fits your workflow.

A: It usually refers to minimum account age, comment karma, or post karma needed to submit content. Check the “About” section of any subreddit to see if there are restrictions before you try to post.
Q: Can I find niche subreddits on the app without using search?
