iPhone App: Known Issues and Limitations
What the iPhone app can and cannot do right now.
On this page
What the iPhone app can and can't do right now, and the limits worth knowing before they surprise you. We update this page as things change.
Recording phone calls isn't possible
Limitation: Groupthink can't record phone or FaceTime calls: not the other person, and not your own side.
Why: iOS gives the microphone exclusively to the call, so no app can record while a call is on. This is an iOS restriction that applies to every app, not something Groupthink can turn on.
What to do: Write notes during the call, or capture the key points afterward: tap the Advisor button and choose Log. If you tap record while you're on a phone call, Groupthink doesn't start a recording and tells you why. See Recording conversations.
Summaries on the phone need iOS 26 and a recent iPhone
Limitation: The app runs on iOS 18 or later, but the summary written on your phone needs iOS 26 and Apple Intelligence. That means an iPhone 15 Pro or newer on iOS 26, with Apple Intelligence turned on in iOS Settings.
What to do: Sign in to Groupthink. Then, on a phone without Apple Intelligence, Groupthink writes the summary instead, and it's labelled Summary by Groupthink. Only the transcript's text is sent, never the audio. Groupthink passes it to its AI model provider to write the summary and doesn't keep the text or the summary; the summary is saved only on your phone. If the summary can't be written, you still get the full transcript, and the app says why (for example "Summaries on this iPhone need iOS 26 and Apple Intelligence.").
The app needs sign-in
Limitation: Signed out, the app shows only its sign-in screen. Recording, notes and every tab need a Groupthink account.
What to do: Sign in with Apple or Google, or with your email and password. Signing in with Apple or Google creates an account if you don't have one. Anything already on the phone comes back when you sign in. See Sync and signing in.
Microsoft sign-in isn't available on iPhone
Limitation: The iPhone app offers Sign in with Apple, Sign in with Google and Sign in with email. Signing in with Microsoft isn't available in the app yet.
What to do: Sign in with Apple or Google instead. Or, if you sign in with Microsoft on the web, set a password: tap Sign in with email, enter your email address and tap Forgot password?, then sign in with your email and the new password. See Sign in with email. You can keep using Microsoft on the web and desktop.
Not on iPhone yet
Some things in Groupthink on the web haven't reached the iPhone app. Today these live on the web:
- Email-in and forwarding notes by email
- Automatic ingestion from meeting bots and other tools
You can still paste a recap, transcript, or link into the phone by hand with Write or paste on the Interactions tab. It's the automatic feed that hasn't reached the phone.
Action items are on the phone. Action items, Activity and Scheduling all open from the buttons at the top of the Today tab, and your tasks for the day are on Today itself.
We're bringing more of the web experience to the phone over time.
