About

Horizon

Features
Read full description

Horizon runs AI on your iPhone and iPad, not in someone else's data center. Pick a model, download it once, and chat. No account, no sign-up, no network required. ALWAYS ON-DEVICE Local models run on your device's own processor. Your messages, the replies, and everything in between stay on the device. They are never sent anywhere. Chats are stored only on your device and are never synced or backed up to us. Incognito chats are not saved at all. THOUSANDS OF MODELS Start with a small model and add bigger ones as you need them. Tiny answers instantly, larger models think harder and write better. Every model shows its download size and its speed before you commit to it. Horizon Pro unlocks every on-device and cloud model, plus browsing and downloading thousands of community GGUF models from Hugging Face inside the app. FRONTIER MODELS WHEN YOU WANT THEM Some questions need more power than a phone can hold. Horizon Pro includes 500 credits a week for frontier cloud models: Claude Opus 5, GPT 5.6 Sol, GPT-6 Astra, Gemini 3.8 Flash, and many more. Cloud models are opt-in. The app tells you clearly before a message leaves your device. BUILT FOR REAL USE - Compare answers side by side. Regenerate a reply and flip between versions. - See tokens per second on every response, so you know what your device is doing. - Incognito chats that are never written to disk. - Several app themes, light and dark. - Full iPad support, including keyboard shortcuts. - Manage your own storage: see exactly what each model takes and remove what you do not need. WORKS WITH NO SIGNAL On a plane, on the subway, abroad without a data plan, or somewhere with no coverage at all. A downloaded model answers exactly the same. PRIVACY No account. No advertising. No tracking across apps. No advertising identifier. The small amount of usage data we collect is anonymous aggregate counts with no user or device identifier attached, used only to see which features people actually use. Cloud models are the one place your words leave the device, by your choice, and only for the message you send. We do not store them. SUBSCRIPTIONS Horizon Plus and Horizon Pro are auto-renewing subscriptions billed to your Apple Account at confirmation of purchase. A subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings.

Verdict

The call

The clearest difference is in-app purchases: Session at none against Horizon's 8. Session also leads on iOS requirement (13.2 vs 26.0). Horizon's advantage is update cadence (every 2 days vs every 4 months). On price, ads and device support there is nothing between them.
