# Finn
**know before your trial charges you — without linking your bank or your inbox.**
iOS app that tracks paid free trials and subscriptions, then warns you before they auto-charge. no bank link, no inbox access, no account.



why
every competitor makes you link something. Rocket Money and Truebill want your bank. Subby and Bobby want your inbox. Finn wants neither.
you capture trials and subscriptions yourself and everything lives on-device. no account, no cloud, no server. free trials are designed to be forgotten; Finn makes sure you don’t.
features
- add a trial with a manual form — merchant name, end date, charge amount
- paste email or receipt text from the clipboard and the on-device parser pre-fills service, date, and amount
- track recurring subscriptions alongside trials
- stored on-device with SwiftData
- local notifications 3 days before and the day a trial ends
- no bank login, no inbox access, no account, no server backend
roadmap: share sheet capture and screenshot OCR are on the way for v1.

status
actively building toward App Store v1. manual entry, paste-to-prefill, on-device storage, subscriptions, and local notifications are working. additional capture methods (share sheet and screenshot OCR) are next.
not yet on the App Store. follow along or star to stay updated.
requirements
development environment
linux cloud agents (Cursor)
- install Swift 6.0 via
swiftly plus runtime deps (libncurses6, libncursesw6) to work on Swift package code
- validate setup with
swift --version after environment bootstrap
- iOS app build/run is not supported on Linux cloud agents because
xcodebuild, xcrun, Simulator, and Apple iOS SDKs are macOS-only
macOS local development
- required for full app build/run and simulator testing
- use Xcode (with iOS SDK + Simulator) to build and launch the app
