Grok Bot mobile app: what you can do on iPhone and Android, plus voice chat (unofficial guide)

What the Grok Bot mobile app can do

Per the official mobile docs, the phone app "connects to the same Bots, conversations, routines, connectors, and shared cloud computer as the desktop app," and work "continues in the cloud when the app is closed." Your phone is a remote control for your Bots. The work itself runs on the Bot's cloud computer.

In a conversation you can send text, dictate with Start dictation, start a live call with Start voice chat, play a voice memo a Bot sent, take or attach a photo, choose an image or file, mention another Bot or @everyone in a group, reply in a thread, and react to a message. Drafts are saved per conversation (docs).

Sharing from other apps: on iPhone, use the share sheet, choose Grok Bot, pick a chat, then choose Attach to drop a photo, file, link, or text into that chat's composer. On Android the share sheet currently accepts text only (docs).

Approvals and drafts: approval cards offer Allow once, Always allow, and Deny, and the docs say the controls are the same on iPhone. When a Bot prepares an email or Slack message, you get a New Email or New Slack Message card with Send Email or Send Message, or Discard.

The computer: open it from a conversation to watch browser work, Take over for a password, two-factor code, or CAPTCHA, then hand control back with I'm done.

Bots, groups, routines, and search: use + on the home screen for New Bot or New Group Chat. A Bot's profile shows its routines with schedule, next run, instruction, and Run history, and the Active switch pauses or resumes a routine. Home-screen search covers Messages, Bots, Group Chats, Files, and Routines.

Voice on your phone: dictation, voice chat, and voice memos

There are three different voice features. Start dictation turns your speech into text in the composer so you can edit it before sending. Start voice chat is a live spoken conversation where the Bot talks back until you hang up. A voice memo is a recording a Bot sends you, with a transcript you can read (docs and Cursor's help center).

To start a call, open one Bot's own chat, leave the message box empty, and tap Start voice chat (the waveform button). Allow microphone access if asked. The phone shows Calling… before the Bot starts talking. During the call you can mute, show the transcript, or open settings to change the Voice, Speed, and Language (Auto-detect picks the language from what you say).

Limits from Cursor's help center: voice chat works with one Bot at a time and not in group chats, only one call runs at a time, and on the phone you should stop dictation before starting a voice chat. If a call drops you'll see Voice chat failed; check your connection and start again.

After you hang up, a Voice chat card in that Bot's chat shows the call length and full transcript. Per xAI's Sep 2026 changelog, if you hang up while the Bot is still working on your request, it finishes and posts the result in the chat.

Grok Voice 3.0, announced Oct 14, 2026, powers Grok Bot's voice mode, per xAI. Voice had a brief outage: on Oct 6, 2026, @lingxi posted "we are temporarily disabling grok @bot voice mode for everyone to address an issue." Users were posting about using voice chat again by Oct 10. If you don't see Start voice chat, clear the message box and update the app.

7 ways founders use Grok Bot from their phone

1. A commute brief by voice. Call your main Bot, ask what needs you today, and hand off two or three tasks out loud. Hang up when you arrive. The Bot keeps working, and the transcript stays in the chat so you can check it later.

2. Approvals from anywhere. Turn on notifications for every Bot that runs routines. The docs say an approval from work that started without you, such as a routine, a trigger, or a message from another Bot, expires after about 10 minutes and doesn't run. Check the recipients, amounts, and targets on the card before you tap Allow once.

3. Capture it on the spot. Snap a receipt, a business card, a whiteboard after a meeting, or a competitor's shelf, then say what to do with it: log the expense, draft a follow-up for your review, or add the notes to a doc.

4. Unblock a stuck Bot. When a Bot needs a login, a two-factor code, or a CAPTCHA, open the computer, Take over, type it yourself, then tap I'm done. Never paste passwords or codes into chat.

5. Steer work in progress. A new message from you takes priority over background work and can redirect it. A direct "Stop now" ends work immediately, but the docs note it doesn't undo actions the Bot already completed.

6. Pause routines while you travel. Open the Bot's profile, review the schedule and Run history, and use Active to pause anything you don't need this week. Turn it back on when you're home.

7. Turn long replies into listening. One user's tip on X: "ask your grok bot to send you a voice note every time it sends you a big paragraph." Handy when you're driving or walking between meetings.

What still needs the desktop (or isn't supported)

Editing a routine's schedule or instruction, and testing a routine, currently require the desktop app. Teach a task (record a demonstration) and "some advanced desktop controls" aren't on mobile either (docs).

Updating or recovering the Bot's computer: Cursor's help center says computer updates aren't available on mobile, and to use desktop Grok Bot to update, recover, or reset the computer.

Routing the Bot's web traffic through your own machine (Route traffic through this computer) and Execution on Local Computer are per-desktop settings. One r/GrokBot user reported they couldn't find an egress toggle in the iOS app, and that the desktop route stops when the desktop is offline.

Your phone's own apps: the docs don't describe any way for a Bot to control apps on your phone, such as WhatsApp, your photo gallery, or iPhone Shortcuts. One user reported on X that their Bot told them it can't control their phone yet. Bots work on their cloud computer and through connectors, so connect services like your email and calendar instead.

One-tap launch: no official home-screen widget or Action Button shortcut is documented. Users have been asking for one on X, and the @grok account said in an Oct 15, 2026 reply that one-tap widgets for quick voice launch aren't available yet, with no public timeline. Some users share workarounds; see our voice guide.

What users report

The upside: "Used Grok Bot today, mostly from my phone. I got more done from my phone with Grok Bot than I usually do sitting at my desk" (@melvindvivas on X, Oct 8, 2026).

Rough edges, as reported by users: an Android user posted on Sep 30, 2026 that photos wouldn't upload in the Android app, and a Google Play reviewer wrote on Sep 18, 2026 that "file outputs do not have a means to simply download to device, only Share to other apps." These may have been fixed since. If something fails, try the share option or open the file on desktop.
