Orbit
Read full descriptionHide full description
Meet Orbit β the assistant that keeps track of what you said you'd do. Orbit turns your calendar, reminders, notes, and messages into a single clear picture of your commitments. Your data stays on your device by default, and nothing is ever sent anywhere until you explicitly approve it. YOUR MORNING, MASTERED Every day starts with a personalized briefing. Orbit surfaces your meetings, reminders, and the commitments you've saved β summarized and ready to act on. No app-hopping, no information overload. Just what matters, right when you need it. ASK ANYTHING Orbit's conversational assistant understands the way you think and talk. Ask "What's on my plate today?" or "Do I have anything free on Friday afternoon?" Orbit connects the dots across your schedule, reminders, and personal memory to give you real answers. Before Orbit sends anything to an AI provider, it shows you exactly what will be sent and asks for your permission. You can revoke that permission at any time in Settings. CAPTURE ANY COMMITMENT Paste an email, a message thread, or a note, and Orbit pulls out the tasks, dates, and promises hiding inside it. Turn any of them into a real Calendar event or Reminder with one tap β you approve every action before it happens. INBOX TRIAGE (PREVIEW) Orbit includes an inbox triage workspace that sorts messages into Needs Reply, Commitments, Newsletters, and Noise. In this version it runs on clearly labeled sample messages so you can try the workflow. Direct Gmail and Outlook sync is planned for a future update. This feature is free for everyone. A MEMORY THAT KEEPS UP WITH YOU The Personal Memory Store keeps the commitments and context that matter to you, stored on your device. Search it, act on it, or delete any part of it whenever you want. PRIVACY YOU CAN INSPECT Your contacts are never uploaded to any server β Orbit reads them on-device only. The Privacy Dashboard shows you exactly what Orbit has stored and where it came from. The Undo Center lets you reverse actions Orbit took, including removing events and reminders it created. One tap erases everything Orbit knows and returns the app to a clean slate. BUILT FOR REAL LIFE Voice input lets you talk to Orbit naturally, hands-free. Native integration with Apple Calendar, Reminders, and Contacts means Orbit fits into your existing workflow without friction. PREMIUM SUBSCRIPTION Orbit is free to use, including inbox triage and 5 AI questions per day. Orbit Premium (Monthly or Yearly auto-renewable subscription) unlocks unlimited AI questions, a smarter AI model, the daily briefing, and unlimited importing. Payment will be charged to your Apple ID at confirmation of purchase. Subscriptions auto-renew unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.

Your model. Your rules. Nabuchodonosor is a private chat interface that connects to the AI engine you choose: Ollama on your local network or Tailscale, or an OpenAI-compatible API available over HTTPS. FREE AT THE APP LAYER The app sends your requests to the model without rewriting, moderating, or adding refusals. Final behavior remains that of the model and provider you choose. EPHEMERAL BY DEFAULT Messages stay in memory only. No history is written to your iPhone. Background clearing is enabled by default. Recent context is off by default; if enabled, it remains limited to this session and 12,000 characters. BRING YOUR OWN MODEL Enter any model name, use an Ollama token provided by the Mac app, or add a key for your compatible server. Secrets are protected in this iPhoneβs Keychain and are not synchronized. VERIFIABLE PRIVACY No Nabuchodonosor account. No analytics, telemetry, uploaded crash reports, or cloud sync. The network session uses no caches or cookies. Important: every request is sent to the engine you configure. If you choose a remote service, its retention practices and restrictions depend on that provider, not Nabuchodonosor.

Verdict
The clearest difference is in-app purchases: Nabuchodonosor at none against Orbit's 2. Nabuchodonosor also leads on iOS requirement (16.0 vs 18.0). On price, ads and device support there is nothing between them.
