YouTube is the world’s most popular video platform, and the YouTube app brings that whole experience to your phone or tablet. In this blog I’ll explain, in simple English, what the app does, how to use its main features, recent changes you should know about, and tips to get more from it. Two helpful images are shown above (the familiar YouTube play-logo and an app icon screenshot).
Quick history: Where the YouTube app came from
YouTube began as a website in 2005 and quickly grew into the place people go to watch and share videos. Google bought YouTube in 2006 and continued developing mobile apps so people could watch videos easily on phones and tablets. The official app is now the main way many people use YouTube every day.

Main things the YouTube app does (easy list)
-
Watch videos anytime — music, news, learning, vlogs, movies, and more.
-
Subscribe to channels — so new videos from creators you like appear in your feed.
-
Shorts — very short, vertical videos (like TikTok) to watch quickly.
-
Upload from your phone — record or upload clips and publish them to your channel.
-
Live streams — watch or broadcast live video from your phone.
-
Personalized recommendations — the app suggests videos based on what you watch.
-
Account tools — playlists, history controls, watch later, and settings. (Google Play)
How to get the app and keep it safe
-
Android: official app on Google Play. Download only from trusted stores (Google Play or Apple App Store) to avoid fake or modified versions. (Google Play)
-
iPhone/iPad: use the App Store.
-
Keep updates on: updates include bug fixes, new features, and security patches — so update regularly.
-
Be careful with third-party APKs: they might include ad blockers or altered behavior and can be risky.
Important features explained simply
Home & Explore
The Home screen shows suggested videos based on your interests. Explore (or trending) helps you find popular videos and categories like music or gaming.
Subscriptions
This tab lists the latest videos from channels you follow. It’s the easiest way to not miss uploads from creators you like. (youtube.com)
Shorts
Shorts are quick vertical videos. They autoplay and are great for fast entertainment or discovering new creators. You can create Shorts directly in the app using the Shorts camera.
Library & History
Your Library stores playlists, uploads, and watch history. You can clear or pause watch history if you don’t want past views to influence recommendations. This is useful when you’re researching something you don’t want saved to your account. (Google Help)
Notifications & Account
Tap your profile picture to manage account settings, subscriptions, purchases (like YouTube Premium), and privacy settings.
Newer things to watch for (recent updates and tests)
-
AI in Shorts: YouTube has been testing generative AI features for Shorts that let creators generate video clips from text prompts (AI-assisted creation tools). This is part of YouTube’s push to make short-form creation faster and easier for creators. Availability may be limited by region. (The Verge)
-
UI experiments: YouTube often tests different mobile layouts — for example, hiding comments or channel details beneath a dropdown to reduce clutter; these tests roll out to some users first. If your app looks different from screenshots online, it may be part of a test.
Tips to use the app better (practical, simple)
-
Use Playlists — create playlists for topics (study videos, workout music, recipes). It makes returning to content easier.
-
Watch offline — YouTube Premium lets you download videos to watch without internet (handy for travel).
-
Control recommendations — use “Not interested” or clear watch history to retrain the suggestions you get. (Google Help)
-
Enable subtitles — many videos offer automatic captions you can turn on when needed.
-
Manage data — enable “Limit mobile data usage” in settings if you’re on a small mobile plan.
-
Report content you think violates rules — every video has a menu to report it; this helps keep the community safer.
For creators: uploading and growing your channel
-
Record on your phone: the app lets you record, add basic edits, and upload without extra software.
-
Use Shorts: short vertical videos can help you get discovered quickly because of the Shorts feed.
-
Engage with viewers: reply to comments and post community updates if your channel has access to the Community tab.
-
Check analytics: in the YouTube Studio app you can see views, watch time, and audience data to improve future videos.
Privacy and family safety
-
Watch history and recommendations: can be paused or cleared from settings. This prevents certain videos influencing future suggestions. (Google Help)
-
Restricted Mode: turn this on to help filter mature content (not perfect, but helpful for parents).
-
YouTube Kids: for younger children, use the YouTube Kids app which is curated for safe, age-appropriate content.
Common problems and quick fixes
-
Video won’t play: check your internet and restart the app. Update the app if the problem continues.
-
App crashing: clear app cache (Android) or reinstall from the official store.
-
Subscription notifications missing: check notification settings for the app and the channel’s notification bell (set to “All” if you want everything).
Final thoughts
The YouTube app is simple to start using, but it also has powerful tools for creators and viewers. Whether you want quick entertainment via Shorts, long-form learning, or to build a channel, the mobile app makes it easy. Keep your app updated, protect your privacy using history and settings, and try the creation tools if you want to publish. For official downloads and support, always prefer the Google Play Store or Apple App Store and refer to YouTube’s help pages.
