Built this over the last few months as a solo iOS dev. The idea: most subscription trackers want Plaid or a bank connection. I wanted one that works from what you can already see (a screenshot of a receipt or your Apple subscriptions page) and keeps everything on the phone. Stack, for the curious: SwiftUI + SwiftData, Vision for on-device text recognition, Apple's Foundation Models when available (with a rule-based parser as fallback), WidgetKit, StoreKit 2. No backend at all. What I learned: Parsing prices across currencies (€, £, ¥, kr, decimal commas) was harder than the AI part "No account, no cloud" is a real selling point, but hard to explain in a single screenshot It's live on the App Store (free tier up to 5 subscriptions): https://apps.apple.com/app/vaultaudit-ai-sub-tracker/id6758683815 Feedback on the positioning or the demo video is very welcome.   submitted by   /u/dagus2020 [link]   [comments]
