Threshold-triggered alarms
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
Threshold-based stock alerting: unified A-share, HK and US coverage with background polling, cooldown, time windows, on-device storage. No login, no tracking.
Stock Alert is a lightweight, opinionated alerting tool for serious investors, built around a single goal: capture your price triggers reliably without forcing you to watch the screen.
ARCHITECTURE
- Quote source: public Sina Finance endpoint covering A-shares (SH/SZ), Hong Kong and US
- Trigger model: percent threshold (up / down / both) computed against previous close
- Cooldown: per-rule cooldown in seconds to suppress flapping
- Time windows: trading hours only / custom range / all day, auto-aligned to each market's session
- Background polling: BGAppRefreshTask + BGProcessingTask schedule continued monitoring while the app is closed
- Notification model: UNNotificationSound + timeSensitive interruption level, ringing up to 30s on the lock screen
- Foreground fallback: switches to AVAudioSession playback so the silent switch can't swallow critical alerts
DATA HANDLING
- All data persisted locally via SwiftData — watchlists, rules, history
- No accounts, no server, no third-party analytics
- Uninstall removes everything; no iCloud residue
DELIVERY METRICS
- Ready to use on launch, single binary under 5 MB
- Only two permissions requested: Notifications and Background Modes
- Requires iOS 17.0+, built on SwiftData and modern SwiftUI
TYPICAL WORKFLOW
1. Add tickers: type sh600519 / 00700 / aapl — market is auto-detected
2. Configure rules: pick the stock, percent, direction, window and cooldown
3. Wait: the system schedules background fetches; on hit, push + alarm fire
4. Review: every trigger appears in the History tab for post-mortem
No sign-up. No subscription. Install and run.
