Hey Product Hunt! 👋 I'm Timothy, the indie maker behind Sentinel. Like many of you, my monthly credit card bill kept inching up. Between dev tools, entertainment apps, cloud services, and gym memberships, subscriptions had quietly taken over my finances. When I tried existing subscription trackers, I ran into two big issues: 1. They demanded my bank logins through aggregators like Plaid, storing my financial history on third-party cloud servers. 2. They felt bloated and non-native, often relying on web views and still missing renewal dates. I built Sentinel with a radically different approach: "Pure Apple DNA with 100% on-device privacy". 🛡️ Why Sentinel Is Different - 🧠 On-Device AI Engine: Analyzes spending patterns, predicts subscription renewal surges over the next 30 days, and flags forgotten subscriptions — all on your device. - 🔒 100% Private: Built with Core Data. No cloud servers, ads, or telemetry SDKs. We never ask for your bank logins or card numbers. - 📸 Receipt & Invoice OCR: Capture a receipt or share a screenshot from Mail or Photos. Sentinel's on-device Vision models extract the vendor, cost, and billing cycle in seconds. - ⚡ Deep Apple Integration: Interactive widgets in Small, Medium, and Large sizes, Lock Screen Live Activities, Dynamic Island renewal countdowns, and Apple Family Sharing. - 💻 Native Apple Experience: Built with SwiftUI for iOS 18, iPadOS 18, and macOS Sequoia. 🎁 Product Hunt Special Sentinel is free forever for tracking up to 5 subscriptions. For Product Hunt makers and early supporters, Sentinel Pro includes a 7-day risk-free trial, followed by: - $19.99/year, or - $2.99/month Family Sharing is included for up to 5 family members. 🚀 Try Sentinel: - Website: https://sentinelpay.app - App Store: https://apps.apple.com/app/id675...
