GuardKit is designed to help you understand when your device may have been moved or interacted with while you were away. GuardKit works by running user-initiated Guard Sessions that analyze motion signals such as acceleration, orientation changes, and handling-like movement patterns. If you choose to enable it, GuardKit can also monitor nearby audio activity levels to provide additional context. All analysis is performed on-device. Key features: • Motion-based activity indicators during active Guard Sessions • Optional audio activity level detection (no audio recording) • Clear, chronological timelines of detected events • Local-first data storage — your data stays on your device • Full user control over permissions and features Premium access: GuardKit offers a free 3-day trial with full access to premium features. After the trial, premium access is available via a one-time purchase (Lifetime Unlock). No subscriptions are required. Learn more at https://www.guardkitapp.com

LinkLens

Features

LinkLens turns any article link into a concise AI summary. Just share a URL from Safari, Chrome, or your favorite news app — no copy and paste, no switching back and forth. Articles pile up in your "read later" list. Some are too long to even start. With LinkLens, you get the key points before you read, so you never waste your limited time. FEATURES - Share to summarize: pick LinkLens from the share sheet and get the key points in seconds. - Three AI engines, works on your device: choose the AI that fits you. Apple Intelligence runs entirely on-device and never sends your articles or URLs anywhere. LinkLens AI needs only an Apple ID sign-in — no API key — and works even without Apple Intelligence. Or bring your own AI (BYOK) with an OpenAI-compatible API and key. - LinkLens AI, credit-based with no monthly fee: sign in and start right away, and buy credit packs only as you need them. No subscription — you pay only for what you use. - Automatic history: every summarized article is saved. Mark favorites to find important ones fast, or re-summarize anytime. - Choose the output language: follow your system language or pick another one — great for getting the gist of foreign-language articles in your own language. REQUIREMENTS - iOS 26 or later - Summarizing with Apple Intelligence requires a supported iPhone or iPad with Apple Intelligence enabled in Settings - LinkLens AI and your own AI (BYOK) also work on devices that don't support Apple Intelligence Terms of Use - https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy - https://rainbow-of-apps.web.app/privacy_policy
