Official DeepSeek App Downloads
Choose the appropriate DeepSeek download below. The store links install the mobile assistant; the browser link opens DeepSeek without an app installation.
| Device or access method | Official destination | What to choose |
|---|---|---|
| Android with Google Play | DeepSeek on Google Play | The store listing for the Android app. |
| iPhone or iPad | DeepSeek on the US App Store | The Apple listing for supported iPhones and iPads. |
| Android APK | DeepSeek’s official download page | Use Download for Android in the DeepSeek app section. |
| Browser access | Official DeepSeek web chat | Use the online assistant without installing the mobile app. |
The download page also contains DeepSeek Harness for desktop. For a phone installation, scroll to the separate DeepSeek app section. The Windows and macOS downloads belong to the desktop product.
How to identify the official app
Both store listings use the name DeepSeek – AI Assistant. Check the publisher and listing address together; an app’s name or icon alone is not enough to establish who publishes it.
- Google Play: the displayed developer is DeepSeek, and the package identifier in the listing URL is
com.deepseek.chat. Its support section links to DeepSeek’s website. - Apple App Store: the app ID is
6737597349. The seller is Hangzhou DeepSeek Artificial Intelligence Co., Ltd. Apple also displays the developer name in Chinese: 杭州深度求索人工智能基础技术研究有限公司.
If you reach an unfamiliar listing through an advertisement or search result, return to the official links above before signing in. A different app may use a DeepSeek model while having a separate operator, subscription, and privacy policy.
How to Download DeepSeek on Android
To install the DeepSeek Android app on a phone with Google Play, start with the official store listing:
- Open the DeepSeek Google Play listing on your phone.
- Check the app title and developer against the identity details above. Confirm that Google Play offers installation for your device.
- Tap Install and allow the download to finish.
- Open the app and follow the sign-in or account-creation instructions it presents.
Google’s Android download guidance recommends Google Play as the usual starting point for installing apps. If Google Play is unavailable on your phone, the official APK route below provides a separate installation option. Device compatibility and service availability still apply.
How to Download DeepSeek on iPhone or iPad
- Open the official App Store listing on your iPhone or iPad.
- Check the seller and the Compatibility section before downloading.
- Tap Get, or the download control shown for an app you have previously obtained.
- Confirm with Face ID, Touch ID, or your Apple Account password if requested.
- Open DeepSeek and complete its account instructions.
Apple explains this process in its app download guide. The Apple Account used to obtain an app and the account you use inside DeepSeek serve different purposes. Completing the App Store download does not necessarily sign you into DeepSeek.
DeepSeek App Requirements and Compatibility
Check compatibility before spending time troubleshooting an installation. The following Apple requirements were listed on November 5, 2026:
| Platform | Requirement or compatibility check |
|---|---|
| iPhone | iOS 15.0 or later, according to the US App Store listing. |
| iPad | iPadOS 15.0 or later. |
| Android | Open the Google Play listing on the device you plan to use and check whether installation is available. |
Google’s app availability instructions explain that a listing shows whether an app is available for your device. A requirement quoted for an older APK does not establish compatibility with a different release.
Availability can also depend on your store account and location. DeepSeek’s Terms of Use state that services and features can vary by jurisdiction. If a listing is unavailable, read the specific message rather than assuming that every download problem has the same cause.
Does DeepSeek Offer an Official Android APK?
Yes. DeepSeek’s official download page links its Android button to the official DeepSeek APK. That second link downloads an Android installation file.
If you use this route, open the download page yourself, find the mobile app section, and follow its Android link. After downloading, open the file and follow your device’s installation prompts. Android may ask you to authorize installation from that source; the wording depends on your device and Android version.
Keep Google Play Protect enabled. Google’s guidance on downloads outside Google Play explains the additional risks and the role of its app checks. If Android displays a security or device-management restriction, resolve the stated issue before proceeding.
An APK is for Android; it cannot install the iPhone app. It also does not remove hardware, operating-system, account, or regional requirements. Return to the official download page when you need an updated installer.
Set Up the App and Start Your First Chat
DeepSeek’s terms describe registration using an email address or a third-party account, following the options on the sign-in page. Choose an available method and complete any requested verification. If you already use the official web service, use your existing account rather than creating another one unnecessarily.
Start with a short request whose answer you can check. For example:
Rewrite the message I provide next as a clear, friendly email of no more than 120 words. Keep the names, dates, and commitments unchanged. If information is missing, ask me before adding it.
Review the response against your original message, then ask for a focused revision. Giving the assistant an audience, a purpose, and a clear output format makes the result easier to assess.
Features to explore after signing in
DeepSeek’s app announcement describes web search, reasoning, file upload, and text extraction. Apple’s release history also documents photo uploads and vision support. Available controls can change between app releases, so follow the labels shown in your version.
Try one feature at a time: summarize a short document, ask a question about an image, or check a factual answer against its linked sources. Confirm that any attachment was accepted before asking the assistant to analyze it. Avoid treating an incomplete upload as a complete document review.
How to Update the DeepSeek App
Use the distribution channel you installed from to check for updates:
- Google Play installation: open the Play Store, tap your profile icon, and select Manage apps & device. Check available updates and update DeepSeek if offered. See Google’s update instructions.
- App Store installation: check DeepSeek’s listing for an available update. If updating fails, follow Apple’s download and update troubleshooting.
- Official APK installation: return to DeepSeek’s download page for the Android installer and follow the device’s update prompts.
Read the release notes when a feature moves or behaves differently. An app version and a model version describe different parts of the service, so a model name in an older guide may not explain the controls on your phone.
Fix DeepSeek Download and Installation Problems
First identify where the process stops. A store download error, a sign-in problem, and an unavailable chat service need different checks.
| Problem | What to check |
|---|---|
| The download stays pending or will not finish | Check your connection and free storage. Reopen the store or restart the phone, then try again. |
| The store says the app is incompatible | Review the listing on that device and check its operating-system requirements. A different download site does not establish compatibility. |
| The listing is unavailable | Read the store’s explanation and check the account, device, and regional conditions that apply. |
| Apple shows a billing or verification message | Resolve the Apple Account issue through Apple Support. Such a message does not, by itself, mean DeepSeek charges for the download. |
| The app installs but you cannot sign in | Use the sign-in method associated with your DeepSeek account and follow its verification or recovery instructions. |
| The app opens but messages fail | Check your connection and the official service-status page before reinstalling. |
For store problems, use Google Play’s basic troubleshooting or Apple’s download support. For a chat outage, check the DeepSeek status page, which reports chat and other service components separately.
If you need to continue without an installation, try the official web chat where available. Browser access is another way to reach the service, but it may be affected by the same account restrictions or service interruption.
What to Know About App Privacy
Confirming the publisher helps you identify the official app. Before sharing private material, also read DeepSeek’s Privacy Policy. It describes collecting information such as prompts, uploaded files, photos, chat history, and device data, along with uses that include operating the service and improving its technology.
Review a permission request when the relevant feature asks for access. For a document or image task, share only what is needed and remove confidential information you are not authorized to upload. Installing an official app does not make every work document appropriate to submit.
DeepSeek App FAQ
Is the DeepSeek app free?
DeepSeek describes its official mobile assistant as free to download and use. Developer API access has separate usage-based pricing. Free mobile access does not promise unlimited requests or identical features in every region.
Can I use the app in English?
Yes. English is among the languages listed on the US App Store page. You can also specify the language you want in your request, such as asking for an explanation in US English.
Will my chats sync between the app and website?
DeepSeek’s app announcement describes cross-platform chat-history synchronization. Use the same account on the official app and web service. If a conversation is missing, check the account and connection before assuming that installing the app created a separate chat history.
Does downloading the app let me run DeepSeek offline?
Plan on an internet connection to use the official assistant. Installing its mobile client is different from downloading model weights and configuring local inference. An Android APK installs the application; it does not establish that AI responses are generated on your phone.
Is DeepSeek Harness the Android or iPhone app?
No. DeepSeek presents Harness as a desktop product with Windows and macOS downloads. For Android or iPhone, use the mobile links in this guide or the DeepSeek app section of the official download page.
Ready to install? Choose Google Play for Android or the App Store for iPhone and iPad. Check the publisher, confirm compatibility, and begin with a small task you can review.
