Quick Apps on Xiaomi: What is it and how to use them

Why did Xiaomi come up with Quick Apps?

If you own a Xiaomi, Redmi or POCO smartphone, you've probably come across the term Quick Apps (or "Fast Apps" in Russian firmware) and it's not just another marketing ploy, it really solves one of the key problems of Android: the overload of the device with unnecessary software. Imagine: you need to use the service urgently, but you don't want to install a full app. Here comes Quick Apps.

They're basically lightweight versions of applications that don't require full installation, they run instantly, take up minimal space, and automatically update. But how does it work? And most importantly, is it safe? In this article, we'll go through all the nuances, from how it works to hidden features that are not even talked about in the official instructions.

What are Quick Apps and How They Are Built

Quick Apps is a technology developed by Xiaomi based on Google’s Instant Apps standard, but it has its own implementation with advanced features from the Chinese manufacturer, the main idea is that the user accesses key features of the app without installing it, such as opening a restaurant map in Meituan, booking a table or paying for an order — all without downloading a full 100+MB app.

Technically, Quick Apps work as native web applications that are loaded on demand, cached in the device’s memory, and deleted after closing (unless added to a favorite), but have access to a limited set of system features — such as sending notifications or using geolocation — but only after explicit user permission.

• 📱 Instant Start: No need to wait for download - the application opens in 1-2 seconds.
• 🗑️ Save space: Do not take up permanent memory space (cache is cleared automatically).
• 🔄 Auto Update: Always up-to-date without manual updates.
• 🛡️ Limited Rights: Do not have access to contacts, SMS or files without permission.

It’s important to understand that Quick Apps aren’t just “cut-down” versions of software; developers optimize them for specific use cases. For example, Xiaomi Pay’s Quick App allows you to quickly pay for a purchase using QR- code, but does not support transaction history or card configurations — it still requires a full version.

Differences between Quick Apps and Normal Apps

At first glance, it may seem like Quick Apps are just stripped-down versions of software, but in practice, the difference goes much deeper.

A critical nuance: Quick Apps can’t run in the background, which means that once closed, they completely stop activity — no notifications or data synchronization. By comparison, a full WhatsApp app can show new messages even when it’s folded, and its Quick version (if it existed) could only send one message and close.

⚠️ Warning: Some Quick Apps may request geolocation or camera access, and always check what permissions they require, which can be a sign of suspicious behavior (especially when it comes to obscure services).

How to Enable and Use Quick Apps on Xiaomi

Quick Apps is activated by default on all Xiaomi, Redmi and POCO smartphones with MIUI 12 and later, but in some regions (e.g. Europe) it may be disabled due to local restrictions to check and enable it:

1. Open Settings → Applications → Quick Apps
2. Activate the switch to Enable Quick Apps.
3. In the Management section you can see a list of available fast applications.

To launch Quick App:

1. Click on a link in your browser, messenger, or other application (such as Mi Browser or Messages).
2. The system will prompt you to open it as a Quick App – confirm the choice.
3. The app will open in a separate window marked Quick App in the top corner.

If you want to save the Quick App for quick access:

• 📌 Click on the three dots in the top corner of the Quick App window.
• 📌 Select Add to the main screen.
• 📌 Now the icon will appear as a regular app, but still won’t take up much space.

Not all apps have Quick versions, but they are currently supported mainly by Chinese services (Meituan, Didi, Weibo) and some global platforms like Booking.com or AliExpress. The full list of Quick Apps available can be found in the Settings menu → Apps → Quick Apps → Catalog.

Quick Apps: What Few People Can Do

Most users use Quick Apps for basic tasks only, but they actually have a few hidden features that few people know about:

• 🔍 Content Search: Some Quick Apps (e.g., Xiaomi Community) allow voice search, even if the full version does not.
• 📤 Data Export: Some Quick Apps allow you to export data in JSON or CSV format directly from the interface (useful for analytics).
• 🎮 Game Mode: Quick versions of games (if you find them) can work with a higher FPS, as they do not load the system with unnecessary processes.
• 🔗 Deep Links: You can create direct links to specific Quick App sections (e.g., open the shopping cart right away in the store).

Another little-known trick: if the Quick App stopped opening, try clearing its cache through Settings → Apps → Quick Apps → Clear the data. This often helps with errors like “Can’t download the application.”

Also worth mentioning is the experimental Quick Apps feature in a split screen, where on some devices (such as Xiaomi 13 Ultra), you can open the Quick App in one window, and in another, a full-fledged app, which is convenient for multi-tasking, but it works unstable and may require inclusion in the developer settings.

Quick Apps Security: Risks and How to Avoid Them

The main question that users are concerned about is how secure is Quick Apps? On the one hand, they're isolated from the system and don't have full access to data. On the other hand, it's still third-party code that runs on your device. Here are the key points:

• 🔒 Sandbox: Quick Apps work in an isolated environment, just like regular apps, but with even more stringent restrictions.
• 🚫 No background activity: Once the Quick App is closed, it shuts down completely, reducing the risk of data breaches.
• 📋 Limited permissions: Access to contacts, SMS or files is only possible after explicit confirmation.
• ⚠️ Potential threats: Attackers can create fake Quick Apps by masquerading as popular services.

The biggest danger is phishing Quick Apps, where scammers can send links to fake versions of banking apps or payment systems, for example, you get a message allegedly from SberBank suggesting that you open the Quick App to confirm the transaction, which is actually a fake page that will steal your data.

⚠️ Warning: Never enter logins, passwords or bank card details into Quick Apps unless you are sure they are 100% authentic. Even if the app looks official, check the domain in the address bar (for Quick Apps, it must start with quickapp:// or miui://).

To minimize the risks:

1. Use Quick Apps only from trusted sources (e.g., the official Xiaomi directory).
2. Turn off the automatic launch of Quick Apps in the settings if you do not use them often.
3. Clean the Quick Apps cache regularly through Settings → Apps → Quick Apps → Clear all data.

Xiaomi also scans Quick Apps for viruses through its built-in Security Scan, but it doesn’t offer a 100% guarantee. For additional protection, you can use third-party antiviruses like Dr.Web or Kaspersky, which can check Instant Apps.

Quick Apps Problems and How to Solve Them

Despite all the advantages, Quick Apps sometimes work in an unstable way, and here are the most common problems and ways to solve them:

If Quick Apps stopped working after the MIUI update, try resetting the app settings:

1. Go to Settings → Applications → Application Management.
2. Click on the three dots in the top corner and select Reset app settings.
3. Confirm the action and restart the device.

On some devices (e.g., POCO F5) Quick Apps may conflict with battery optimization.

1. Open Settings → Battery and Performance → Battery Optimization
2. Find the Quick App Service list and turn off optimization for it.

💡

If the Quick App is constantly rebooting, try disabling VPN or proxy services – some services block access due to geo-restrictions.

The Future of Quick Apps: What to Expect from Xiaomi

Quick Apps is a technology that is growing rapidly, and Xiaomi has ambitious plans to expand it, with the following innovations expected in the upcoming MIUI updates:

• 🌍 Global expansion: While most Quick Apps are focused on the Chinese market, Xiaomi promises to add support for European and American services in 2026.
• 🤖 AI integration: Fast apps will be able to use the capabilities of Xiaomi HyperOS to personalize content (e.g., Quick App Mi Video recommendations based on your preferences).
• 🎮 Game Quick Apps: There will be lightweight versions of popular mobile games with the ability to synchronize progress with full versions.
• 🔄 Offline Mode: Some Quick Apps will be able to work without the internet, while retaining basic features (e.g., viewing previously downloaded tickets at 12306).

The plan also includes integration of Quick Apps with Xiaomi smart devices, such as the ability to control Mi Robot Vacuum or Mi Air Purifier directly from the Quick App without installing the full Mi Home app, which is especially true for memory-limited devices like the Xiaomi Watch 2 Pro.

But there are risks: Quick Apps could become a target for fraudsters as they expand their functionality, and in China, there are already cases where attackers are swapping legitimate Quick Apps for fake ones to steal user data. Xiaomi promises to increase moderation, but users will still have to be vigilant.

💡

Quick Apps is not just a temporary solution, but a strategic step for Xiaomi to move towards a cloud ecosystem where most of the features will be available without installing apps.
