How we ranked these
Order = Google Play review count on 2026-11-03. Average star ratings (4.5 to 4.8) are shown but do not change the order.
| Criterion | Weight | How it is measured |
|---|---|---|
| Google Play review count | 100% | Number of reviews shown at the top of each US Google Play listing on 2026-11-03. Used as the adoption signal; it decides the order. |
| Scope | General AI assistant apps with an official Android listing from the vendor and an assistant entity on PlugWiki: OpenAI, Google, Perplexity and Anthropic. Microsoft's Android listing titled Microsoft Copilot (package com.microsoft.office.officehubrow, 9.3M reviews on 2026-11-03) describes itself as AI built for work and connected to Word, Excel, PowerPoint, Outlook and Teams, so we treat it as a Microsoft 365 work app and do not rank it. We could not find a separate consumer Copilot listing on US Google Play that day. Grok and Meta AI are not ranked because we hold no entity or page for them yet. | |
| Facts shown | Ratings, downloads, content rating and update dates come only from each Google Play listing. Connectors come from the listing text and, for Claude, the vendor help center. Star ratings are shown but do not change the order. |

Questions
What is the best free AI app for Android?
Our advice: ChatGPT for most people. Its Google Play listing says the app is free, and it has about 67 million reviews at 4.8 stars. Perplexity's listing also calls its app free. The Gemini and Claude listings list in-app purchases and do not use the word free.
Are AI apps on Android free?
The ChatGPT and Perplexity listings both say the app is free. ChatGPT, Perplexity and Claude list in-app purchases, and Gemini's listing points to Google AI Plus, Pro and Ultra upgrades. ChatGPT also shows ads.
Can an AI app on Android read my email and calendar?
Yes, if you connect it. Gemini connects to Gmail, Calendar, Google Photos, YouTube and Search. Claude connects to Google Drive, Gmail and Calendar. The ChatGPT and Perplexity listings do not mention connecting mail or calendar.
Does Gemini replace Google Assistant on my phone?
Only if you opt in. The Gemini listing says that if you opt in, it replaces Google Assistant as the primary assistant, some Assistant voice features are not available yet, and you can switch back in settings.
Do Claude connectors work in the Android app?
Yes. Claude reaches a connector from Anthropic's cloud, not from your phone, and Anthropic says that holds across every Claude client, including the mobile apps. The server has to be reachable on the public internet.
Which AI app is best for research with sources?
Our advice: Perplexity. Its listing promises cited sources for every answer. Claude's listing also says it searches the web and compiles findings with citations.
Which AI app has the most downloads on Android?
Among the four ranked apps, ChatGPT and Gemini, which both show 1 billion or more downloads on Google Play. Perplexity shows 100 million or more and Claude 50 million or more.
Can ChatGPT see my screen on Android?
In limited availability, yes. The listing says users can choose to let ChatGPT answer questions about what is on screen using Accessibility Services, without uploading screenshots.
Are these Android AI apps the same as the iPhone ones?
The same four assistants exist on both, but the stores differ in ratings and age labels. The iPhone list also ranks Microsoft Copilot; on Android we left it out because its US Google Play listing is a work app (see the method).
