Common questions

The app says my device isn't supported. Why?

Nod requires an iPhone that supports Apple Intelligence and is running iOS 26.0 or later. That means iPhone 15 Pro / Pro Max or any iPhone 16 or later. Older devices don't have the on-device model Nod is built around.

I tapped the engine I want and nothing happened.

The first time you switch to an open-weights engine (Qwen 3, Qwen 3.5, or Gemma 4), Nod downloads its weights — about 2 to 3 GB. The download defaults to Wi-Fi only and runs in the background. You'll see a progress indicator in settings. Once it's done, that engine runs entirely on-device and never re-downloads.

Why does the download seem stuck?

A few common causes: you're on cellular and haven't opted into cellular downloads (toggle in settings), you're on a metered or restrictive network, or Background Assets is throttled by iOS while the device is in low power mode. Plug the device in, connect to Wi-Fi, and the download should resume automatically.

Where are my conversations stored?

In a local SQLite database on your iPhone, encrypted at rest by iOS. Nothing is uploaded. If you've enabled iCloud backup for your iPhone, the database is included in your standard iCloud backup under your Apple account — not anything we run.

How do I delete everything?

Inside the app, tap Start fresh in settings. That permanently deletes the local conversation, running summary, and memory on this device. To go further, delete the app — iOS removes the database with it.

Does Nod work offline?

Yes. Once the engine you've selected is on the device (Apple Intelligence ships with iOS; the open-weights engines are downloaded once), Nod is as offline as your camera. Airplane Mode is a fine way to test it.

Can I use a different language?

Apple Intelligence and the open-weights engines all handle a wide range of languages. The app's interface is currently English-only; we plan to add more languages.

Voice input doesn't seem to work.

Make sure you've granted microphone and speech-recognition permissions when prompted. If you skipped those prompts, re-enable them in iOS Settings → Privacy & Security → Microphone (and the same path for Speech Recognition). Both run entirely on-device using iOS 26's SpeechAnalyzer.

How do I turn on Face ID?

In settings, toggle Require Face ID. After that, opening the app prompts for Face ID before the conversation appears. Useful when you share your phone or hand it around.

Is Nod a substitute for professional help?

No. Nod is a general-purpose AI chat app — a calm conversation partner, not a counselor, doctor, or therapist. If you're in a crisis or need professional support, please contact local emergency services or a qualified professional in your country.

Is Nod really open source?

Yes. The full Swift source — the UI, the model wrappers, the system prompts, the database schema — is on GitHub at github.com/Speculative-Dynamics/nod under the MIT license. The build on the App Store is signed from the maintainer's account but built from the code in the repo.

I have a feature request.

Open an issue on GitHub with the enhancement label, or email hello@usenod.app. We can't promise everything ships, but we read everything.
