If you want DeepSeek on Android — the official chat app, not a look-alike — the short answer is: install it from Google Play in supported regions, or grab the signed APK linked from deepseek.com. That gets you the same DeepSeek V4 model that powers the web chat, with the DeepThink toggle for reasoning mode, conversation history synced to your account, and voice input on most handsets. Sideloaded copies from random mirrors are the main risk: counterfeit DeepSeek apps have shown up repeatedly since early 2025, some bundled with malware. This guide walks through verifying the real app, installing it cleanly, configuring the settings that matter, and deciding when the phone app is enough versus when you should switch to the API.

The direct answer: where to get DeepSeek on Android

DeepSeek ships one official Android client, published by Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd. You have two legitimate install paths:

1. Google Play Store — search for “DeepSeek — AI Assistant” and confirm the developer name before tapping Install. This is the path to use if Play is available in your country.
2. Signed APK from deepseek.com — the company links a direct APK download from its homepage for regions where Play listings are restricted. Only use the link that starts at deepseek.com, never a third-party APK mirror.

If either option looks unfamiliar, cross-check against our verify official DeepSeek app checklist before tapping install. Counterfeit DeepSeek apps have surfaced repeatedly on alternative app stores since the V3 launch; some bundled adware, others requested permissions a chat app has no business asking for.

Is DeepSeek available in my country?

Availability varies. The app is live on Google Play across the US, UK, Canada, Australia, New Zealand and Ireland as of April 2026. Italy’s Garante ordered blocking of the DeepSeek app in January 2025 over data-protection concerns, and several US states (Texas, New York, Virginia among them) restrict DeepSeek use on government-issued devices — personal devices remain unaffected. There is no US federal ban. For the current country-by-country picture, see our DeepSeek availability by country tracker.

Minimum requirements and compatibility

The official app is light. What matters:

• Android version: 8.0 (Oreo) or later. Anything newer than 2018 should be fine.
• RAM: 3 GB minimum; 4 GB+ recommended if you keep many long conversations open.
• Storage: roughly 150 MB installed, plus conversation cache.
• Network: inference runs on DeepSeek’s servers, so you need a working connection. Nothing runs on-device.
• Account: email, Google, or phone-number sign-in. See sign up for DeepSeek if this is your first time.

If you want local inference on an Android device (no cloud calls), skip to the “Running DeepSeek locally on Android” section below — the official app does not do that.

Step-by-step: installing DeepSeek from Google Play

1. Open Play Store and search “DeepSeek”. The first result should show the developer as “Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd.” If it does not, stop and check our verification guide.
2. Tap Install and wait for the download (typically 30–60 MB).
3. Open the app and sign in — email, Google or phone number. You can also create a new account inline.
4. Grant microphone permission only if you plan to use voice input. Deny everything else on first launch; you can reverse any decision later in Settings → Apps → DeepSeek → Permissions.
5. Choose the model. The default is DeepSeek V4. The “DeepThink” toggle at the bottom of the compose bar switches V4 between non-thinking and thinking mode.

Step-by-step: sideloading the official APK

Only use this path if Play Store is unavailable in your region. Skip any site that is not deepseek.com.

1. Open a browser and visit deepseek.com directly — type the URL, do not follow a link from social media or an ad.
2. Tap the Android download link on the homepage. Save the APK file to your Downloads folder.
3. When Android prompts “Allow this source to install apps?”, grant the permission to your browser only. Revoke it after install.
4. Open the downloaded APK and tap Install. Confirm the signing certificate matches DeepSeek’s publisher details if your device surfaces that dialog.
5. Launch the app and sign in as above.

What you get in the Android app

Feature-wise the mobile app mirrors the web chat, not the API. Key capabilities:

The distinction matters. The web chat and Android app maintain session history on DeepSeek’s side; the developer API at POST /chat/completions is stateless, and clients have to resend the full message history with each request. If you want to build something custom around the phone, you are using the API, not the app — see our DeepSeek on mobile tutorial for that path.

Using DeepThink mode on your phone

The DeepThink toggle sits next to the message input. Tapping it puts V4 into thinking mode, where the model produces a reasoning trace before answering. On mobile the trace displays in a collapsible section above the final answer — in API terms this is reasoning_content alongside the final content.

When to leave DeepThink off:

• Quick factual lookups and short rewrites.
• Conversational back-and-forth where latency matters.
• Anything you want to paste into another app within a few seconds.

When to turn DeepThink on:

• Multi-step reasoning (maths, logic puzzles, planning).
• Debugging code you have pasted into the chat.
• Comparing options where you want the model to show its workings.

Privacy settings worth checking on first launch

DeepSeek processes conversations on servers in China, which is where the legal framework around data requests differs from Western jurisdictions. That is not a reason to avoid the app, but it is a reason to configure it deliberately.

• Training opt-out. In Settings → Data Controls, look for the option that excludes your conversations from model improvement. Toggle it off if you are discussing anything sensitive.
• Chat history. You can disable history for a session or delete individual conversations. Deletion removes them from your account view; for deeper guarantees, review our DeepSeek privacy breakdown.
• Permissions. Only microphone (voice input) and storage (file upload) are genuinely needed. Deny contacts, location and anything else.
• Biometric lock. If your Android supports app-level biometric locking, enable it on DeepSeek so someone picking up your unlocked phone cannot scroll your history.

Android app vs web browser: which should you use?

If you mostly chat on mobile, install the app — it handles Android’s share sheet (you can send selected text or an image straight to DeepSeek from any other app), supports voice input, and survives network drops better than a browser tab. If you are at a desk more than on your phone, the web chat plus a pinned Chrome shortcut is usually enough. Our DeepSeek browser vs app comparison walks through the trade-offs in detail.

Running DeepSeek locally on Android

The official app is a thin client over DeepSeek’s cloud. If you want genuine on-device inference — no account, no network, no data leaving the phone — you need a third-party runtime and a small open-weight model. Realistic options:

• MLC LLM or llama.cpp Android builds running a quantised DeepSeek R1 Distill (1.5B or 7B) checkpoint. Works on flagships with 8 GB+ RAM; expect 3–10 tokens per second depending on the chip.
• Termux + Ollama — heavier setup but gives you the desktop-style workflow. Same model-size constraints apply.

What you will not run on a phone: V4-Flash (284B total / 13B active) or V4-Pro (1.6T total / 49B active). Those are data-centre models. For the local approach, start with our DeepSeek R1 Distill overview and the broader install DeepSeek locally tutorial.

If you need the API from your phone

Some readers land here looking to drive DeepSeek from an Android app they are building, not to chat. The surface you want is the OpenAI-compatible endpoint at POST /chat/completions against https://api.deepseek.com. A minimal Python example using the OpenAI SDK:

from openai import OpenAI

client = OpenAI(
    base_url="https://api.deepseek.com",
    api_key="sk-...",
)

resp = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[{"role": "user", "content": "Summarise this email in 3 bullets."}],
    temperature=1.3,
    max_tokens=512,
)
print(resp.choices[0].message.content)

Two things to know before you wire this into a mobile app. First, V4 ships as two open-weight MoE tiers under MIT: deepseek-v4-flash (the cost-efficient default) and deepseek-v4-pro (frontier tier). Thinking mode is a parameter on either — set reasoning_effort="high" with extra_body={"thinking": {"type": "enabled"}}. Second, the legacy IDs deepseek-chat and deepseek-reasoner still work but retire on 2026-07-24 at 15:59 UTC; both currently route to deepseek-v4-flash. Migration is a one-line model= change — base_url does not change. DeepSeek also exposes an Anthropic-compatible surface against the same base URL if you prefer that SDK.

For a deeper walk-through, see the DeepSeek API getting started tutorial and the current DeepSeek API pricing page. As of April 2026, V4-Flash lists $0.028 cache-hit, $0.14 cache-miss, and $0.28 output per million tokens; V4-Pro lists $0.145 / $1.74 / $3.48. Default context window is 1,000,000 tokens with output up to 384,000 on both tiers.

Common problems on Android

Who the Android app is for — and who should skip it

The mobile client is the right starting point for casual use, quick drafting, Q&A, translation, and light coding help on the go. It is not the right tool if you need scripted automation, bulk processing, or integration with another product — those are jobs for the API. If you are still weighing general fit before installing anything, our DeepSeek beginners guide is a better starting point, and the wider set of DeepSeek beginner guides covers platform-by-platform setup.
