Reddit is a social platform where people join communities called subreddits to discuss topics, post content, and comment on other posts. The official Reddit Help Center describes it as “the heart of the internet,” where millions of people talk about any topic imaginable.
Key takeaways
- Reddit is organized around subreddits, which are topic-based communities.
- Users interact through posts, comments, and an upvote/downvote system that surfaces the best content.
- The official mobile apps are supported only on iOS 15+ and Android 9+ for the latest versions.
- Reddit documents separate iPhone and Android settings paths for accessibility, media, and NSFW content controls.
How Reddit works
Reddit’s structure is built entirely around its community-based model. When you create an account, you can find and join subreddits, communities dedicated to specific topics, from technology to cooking to cute animal pictures. Once you subscribe to a subreddit, its posts appear on your personalized home feed. Posts can be articles, images, videos, or text discussions. You engage with them by upvoting (liking) or downvoting (disliking), and by leaving comments to join the conversation. The voting system determines which content rises to the top of each subreddit and your feed, ensuring the most relevant or popular material is seen first.
Getting the Reddit mobile app
The first practical step for new users is downloading the official Reddit app. The official iPhone and Android Reddit apps are supported on current minimum operating system versions of iOS 15 and Android 9. Reddit says devices running Android 8 or below, or iOS 14 or below, cannot download the latest versions of the app. To get the app, download the latest official version from the app store associated with your device. Reddit also maintains separate help sections for the official iOS app and official Android app, and a general app section that includes minimum supported OS versions and other mobile-app help topics. This is the hub for the site's social, messaging and account apps.
What to do next
Once you have the app, explore the settings to tailor your experience. On iPhone, for larger text, Reddit documents this path: open iOS Settings, tap Accessibility, under General select Per-App Settings, tap Add App, choose Reddit, then tap Reddit and select Larger Text. For reducing motion or media animations on iPhone, Reddit says to open iOS Settings, tap Accessibility, and then Media and animations. For iPhone NSFW visibility, open the iOS Settings app and toggle Show NSFW Content (18+) to your preference. On Android, open the Android Reddit app, go to Settings, then under View options toggle Show mature content (I’m over 18) as desired. Reddit’s Android FAQ also documents a View options section in the app for this setting. Reddit documents official in-app support and settings through its mobile app help pages, but the specific menu path varies by platform and by feature. For some features, Reddit gives only the setting name and not a full navigation path.
Frequently Asked Questions
What is a subreddit?
A subreddit is a topic-based community within Reddit, each focused on a specific interest, hobby, or discussion area. Users can join subreddits to see posts and participate in conversations about that topic.
Do I need an account to use Reddit?
You can browse Reddit without an account, but you need one to post, comment, vote, or subscribe to subreddits. An account also personalizes your home feed based on the communities you join.
What happens if my device is too old for the latest Reddit app?
If your device runs Android 8 or below, or iOS 14 or below, you cannot download the latest version of the official app. Reddit says the app version support floor can change; in March 2026 it said it would no longer support app versions below Android v2022.16 and iOS v2022.05 starting March 18, 2026.
How do I find subreddits I might like?
Use the search bar within the app or website to look for topics you enjoy. Reddit also suggests popular subreddits during account setup and on the home feed.
Can I change my NSFW content settings later?
Yes. On iPhone, use the iOS Settings app to toggle Show NSFW Content (18+). On Android, open the Reddit app’s Settings and toggle Show mature content (I’m over 18) under View options.
