Check the developer first
Before installing, tap the developer name on the store listing. If it isn't OpenAI, it isn't the official app — no matter how similar the icon looks.

Watch out
Fake ChatGPT apps & copycat brands
ChatGPT's popularity has spawned a wave of imitators — apps and websites that borrow the name, the logo or a similar interface but are not made by OpenAI. Many are harmless wrappers; some charge steep subscriptions for a free service, or worse, harvest your data. Here's how to tell the real thing from a copycat.
| Signal | The real ChatGPT | Common imitator red flag |
|---|---|---|
| Developer / publisher | Listed as OpenAI on the App Store and Google Play. | Some unknown studio or generic "AI apps" account you've never heard of. |
| Name & spelling | Simply "ChatGPT". | "Chat GBT", "GPT Chat", "AI Chat GPT", "Chat AI GPT-4", "Open Chat GPT" and similar mash-ups. |
| Price | Free to download and use; optional Plus/Pro upgrade. | Forces a weekly/annual subscription immediately, or a "3-day trial" that auto-charges. |
| Official website | chatgpt.com / openai.com. | Look-alike domains, or no clear company behind it at all. |
| Reviews & downloads | Millions of downloads, long review history. | Few downloads, a burst of five-star reviews, or many complaints about billing. |
Read the exact name
Copycats rely on you not looking closely. "Chat GBT" or "GPT AI Chatbot" are not typos in your memory — they're different products trading on the resemblance.
Watch the paywall
If an "AI chat" app demands payment before you can type a word, back out. The genuine app lets you chat for free on a standard account.
Ignore links in ads & email
Only install from the App Store or Google Play, or from chatgpt.com. Never from an APK site, a pop-up ad, a text or an emailed "download" link.
Not every ChatGPT-like app is a scam — many are genuine, different AI assistants worth considering. The difference is honesty: a real alternative tells you what it is instead of pretending to be ChatGPT.

Feature tour
What you can do in the app
The mobile app is more than a chat box. These are the features people actually reach for on a phone.
Voice conversations
Tap the voice icon and just talk. Standard voice works on the free tier; Advanced Voice adds natural, real-time back-and-forth on eligible plans. Great hands-free. Voice mode →
Camera & image input
Snap a photo or upload one and ask about it — a menu, a math problem, a landmark, a screenshot. The app reads and reasons about images on supported plans.
Files, search & GPTs
Upload documents, let ChatGPT search the web for current info, and open custom GPTs — all from your phone. Full feature list →
Sync across devices
Your conversations and settings sync with the website, so you can start on your phone and finish on a laptop. Sign in with the same account everywhere.

FAQ
ChatGPT app — quick answers
The most common questions about using ChatGPT on a phone.
Is the ChatGPT mobile app free?
Yes. The official ChatGPT app for iPhone and Android is free to download and free to use with a standard account. A paid ChatGPT Plus (or higher) subscription adds higher limits, newer models and features like Advanced Voice, but you don't need to pay to use the app for everyday chat. Always download the official app from the App Store or Google Play to avoid paid fakes.
How do I download the official ChatGPT app safely?
On iPhone, open the App Store and search for ChatGPT by OpenAI; on Android, open Google Play and search for ChatGPT by OpenAI. Check that the developer is listed as OpenAI, look at the rating and download count, and avoid clones that charge upfront or copy the logo. Never install ChatGPT from an unofficial APK site or a link in an ad or email.
Does the ChatGPT app have voice mode?
Yes. The app includes a voice feature that lets you speak to ChatGPT and hear spoken replies. There's a standard voice option and, on eligible plans, an Advanced Voice mode with more natural, real-time conversation. Availability and exact behavior depend on your plan, region and app version, so check the app and OpenAI's help center for current details.
What can the ChatGPT mobile app do?
The app supports text chat, voice conversations, image input (take or upload a photo and ask about it), file and document uploads, web search, and access to custom GPTs on supported plans. You can sync conversations with the website, use it hands-free, and continue chats across devices. Exact features vary by plan and app version.
Why is the ChatGPT app not working?
Common causes are a weak connection, an outdated app, a temporary OpenAI outage, or a login problem. Try switching between Wi-Fi and mobile data, force-closing and reopening the app, updating it in the store, and restarting your phone. If ChatGPT is down for everyone, check OpenAI's status page and wait. Sign-in loops often clear after updating the app or resetting your password.
Is the ChatGPT app different from the website?
They share your account and history, but the app adds mobile-first features like voice conversations, camera input and notifications, while the website can be handier for long documents, copy-paste and side-by-side windows. Most core features exist on both, though new features sometimes arrive on one platform first. Use whichever fits the task.
Does the ChatGPT app work offline?
No. ChatGPT runs on OpenAI's servers, so the app needs an internet connection to send your messages and receive replies. Without a connection you can read past conversations that are already loaded, but you can't get new answers. If responses stall, it's usually a connection or server issue rather than the app itself.
Is the ChatGPT mobile app safe to use?
The official app from OpenAI is widely used and available in the Apple App Store and Google Play. As with any AI tool, avoid sharing sensitive personal, financial or confidential information, review your data controls in Settings, and be aware that conversations may be used to improve models unless you opt out. Only install the genuine app to avoid scam clones.
