Free · In‑App Purchases
iPhone
Silica is a location and stay history app for giving AI your actual activities—not your plans.
It automatically records the places you visit and how long you stay on your iPhone. Review where you went and how long you stayed in a daily timeline and map. You do not need to open the app every day.
【Key Features】
• Automatically record places visited and stay durations in the background
• View activity history in a daily timeline and map
• See travel modes such as walking, cycling, and driving
• Save frequently visited places
• Manually or automatically export history to Markdown or Notion
• Use exported history as context for any AI agent or knowledge tool
Silica does not include built-in AI. It is a recording foundation for giving your AI real-world activity data.
【Features】
• Location history is primarily stored on your device. Only selected logs are sent to Notion when Notion integration is enabled
• No ads or advertising tracking
• Minimal use of location services enables low-power recording
Background recording requires Always location access and Precise Location. Records may contain omissions or inaccuracies depending on the device and environment.
Some features require Silica Pro.
