How To Use ChatGPT On Your Phone

Download the free ChatGPT app from the App Store or Google Play, checking it's made by OpenAI. Sign in with your email, Apple or Google account. Then tap the message box, type or say a question in everyday words, and read the reply. You can also talk to it or show it a photo.

Steps last checked: 16 October 2026, on OpenAI's help centre. Buttons may look slightly different after app updates.

How Do I Get The Real ChatGPT App?

1. On an iPhone, open the App Store. On an Android phone, open Google Play.
2. Search for ChatGPT.
3. Check the app is made by OpenAI before you tap Get or Install. Copycat apps use similar names and logos.
4. The app is free to download. You don't need to pay to start.

How Do I Sign In?

1. Open the app and tap Sign up or Log in.
2. Use your email address, or continue with an Apple, Google or Microsoft account you already have.
3. Follow the steps on screen. You may be sent a code by email to confirm it's you.

Once you're in, turn on a second sign-in step to protect your account. See how to lock your ChatGPT account.

How Do I Ask My First Question?

1. Tap the message box at the bottom of the screen.
2. Type a question in everyday words, for example: "What can I cook with eggs, cheese and spinach?"
3. Tap the arrow to send it, then read the reply.
4. Ask a follow-up, such as "Make it simpler" or "Which one is quickest?"

Can I Talk To ChatGPT Instead Of Typing?

Yes. There are two ways:

• Dictation: tap the microphone, speak your message, and it turns into text you can check before sending.
• Voice conversation: tap the Voice icon in the message bar to talk back and forth, a bit like a phone call. The first time, allow the app to use your microphone and choose a voice you like.

OpenAI says a voice conversation can carry on while you use other apps or lock your phone. When you've finished, tap the exit button to end it.

How Do I Ask About A Photo?

1. Tap the + button next to the message box.
2. Take a photo, or choose one from your photos. Try a confusing letter, a plant or a menu in another language.
3. Ask: "What does this mean?" or "What is this plant?"

Cover or crop out account numbers and other private details first.

What Are Some Good Things To Try?

"Explain this letter from my energy company in simple words." (attach a photo)

"Give me a gentle 10-minute stretching routine for someone in their seventies."

"Help me write a birthday message for my granddaughter who loves horses."

"What questions should I ask the plumber before he starts?"

How Do I Stay Safe?

• Never type passwords, bank or card numbers, or PINs.
• ChatGPT can be wrong. Check health questions with your doctor or pharmacist, and money questions with your bank or a qualified adviser.
• The free version really is free. If a website or caller asks you to pay to "unlock" ChatGPT, it's a scam.
