Short answer: yes, AskWatch is laid out for iPhone Duo. Open it and the main screens use the extra width — a sidebar beside the content, two answers side by side; fold it and the outer screen works like any iPhone. One free download covers iPhone Duo, Apple Watch, iPad, Mac, Apple TV and CarPlay.
What changes when you unfold it
A stretched phone layout wastes a wide screen. On the open iPhone Duo, AskWatch gives the screens where a second column helps a wide layout instead:
- Chat — the list of conversations on the left, the conversation you are in on the right. Switch between chats without leaving the one you are reading.
- Compare — ask once and read two models’ answers next to each other. No switching back and forth.
- Home — with Home Assistant connected, rooms, favourite devices and sensor values in one dashboard, with a room panel beside them.
- AI providers — the providers on one side, the selected provider’s key and model on the other.
- Settings — categories on the left, details on the right.
- Notes — the list beside the note you are reading.
- Live Conversation — the transcript beside the voice controls when the screen is wider than tall, below them when it is upright.
Held upright, the open screen gives you a tall chat with more of each answer in view.
Two AI answers, side by side
Compare is the screen the wide display was made for. Pick two providers — say ChatGPT and Claude — ask one question, and both answers appear next to each other. You see at a glance which model suits the task, and you can carry on in a full chat with whichever answer you liked. Compare is part of PRO; the free version includes 3 comparisons a day.
Your home on the big screen
With Home Assistant connected, the open screen shows rooms, favourite devices and sensor values together, and with AI-enhanced control switched on you can ask about any of them or switch something in plain words. With PRO, Live Activities keep the sensors you pick on the Lock Screen and in the Dynamic Island.
Folded, nothing is missing
Closed, iPhone Duo is a regular iPhone, and AskWatch is the regular app: chat with your providers, pick another model from the chat, control your smart home and follow it as it changes. Nothing is reserved for the open screen except the extra column.
The rest of AskWatch comes along
- Many AI providers in one app — OpenAI (ChatGPT), Anthropic (Claude), Google (Gemini), xAI (Grok), Perplexity, Mistral, DeepSeek and more, or your own server.
- Voice — dictate, talk hands-free, or hold a Live Conversation with ChatGPT, Gemini or Grok, and have answers read aloud in premium voices.
- Apple Watch, Mac, iPad, Apple TV and CarPlay — the same app, with your keys carried over by iCloud Keychain.
- Web search, notes and real-time context — weather, exchange rates and your own notes in the answer when you allow it.
- Privacy — with your own key, chat requests go straight from your device to the provider; on a subscription they go through AskWatch’s server. Chat history is encrypted on the device.
How you pay
The app is a free download. For the AI, use your own API key from a provider — you pay the provider for what you use and AskWatch adds nothing to it — or subscribe to AskWatch+ or AskWatch Ultra and use managed models without opening an API account. Features such as Compare and Live Activities are part of PRO: a one-time purchase, and included in both subscriptions.
Questions people ask
Does AskWatch support iPhone Duo?
Yes. On the open screen, Chat, AI providers, Settings and Notes show a sidebar beside the content, Compare puts two answers side by side, Home adds a room panel, and Live Conversation adapts to how you hold the phone. On the outer screen the app works as it does on any iPhone.
Is iPhone Duo the same as the iPhone Fold?
Yes. Before Apple announced it, the foldable iPhone was widely called the iPhone Fold; Apple sells it as iPhone Duo.
Can I use ChatGPT and Claude at the same time on iPhone Duo?
Yes. The Compare screen sends one question to two providers and shows both answers next to each other on the open screen. Compare is part of PRO, and the free version includes 3 comparisons a day; each provider needs your key or a subscription that includes it.
Do I need a separate purchase for iPhone Duo?
No. iPhone Duo runs the iPhone app; one App Store listing covers iPhone, Apple Watch, iPad, Mac, Apple TV and CarPlay.
Does it work with Apple Watch too?
Yes. AskWatch started on Apple Watch — ask by voice from your wrist, and continue the conversation on the open iPhone Duo.
