About this app

Stock Journal is a private investment journal for recording stock research, investment theses, market news, and analyst report notes. Write down why a stock interests you, save your target price and personal view, and review how your thinking changes over time.

Organize research notes by stock, market, theme, and issue. When earnings, company updates, or major news arrive, revisit your original investment thesis and decide whether your reasons still hold.

Remember why you became interested in a stock, what assumptions supported your view, and which news changed your mind. Stock Journal helps you build a dated history of your research and investment decisions instead of leaving disconnected notes across different apps.

Your records are stored in the app’s private storage on your device. You can optionally back up and restore them through the private app-data area in Google Drive.

This app does not provide live stock prices, automated trading, or investment recommendations. Target prices and investment views entered in the app are personal records and do not guarantee investment returns.

Build your own stock research journal and revisit your investment thesis with context whenever new information appears.
