Keep market data, technical signals and your own research together, with less switching and more context.
Explore composite scores, stock-pool sentiment and breadth. Adjust indicator weights to understand what contributes to each signal.
Manage stock pools, watchlists, manually recorded holdings and research notes. Keep them on your phone and export a backup when needed.
Run historical backtests on your device. Results use the current stock pool and weights, exclude trading fees, and do not predict future returns.
Core features work without an account. Optional Apple or Google sign-in connects your AICOFI account; signing in does not automatically upload or sync local holdings, notes or watchlists.
Stock Signal is a technical analysis and personal research tool, not an investment adviser or brokerage. Third-party market data may be delayed, incomplete or inaccurate. Check its date and source. Alerts are checked only while the app is open and updating data.
