SQL Notebook

SQL, tables, charts and notes

Free

Write SQL, explore results, and keep your analysis in a notebook on iPhone and iPad. SQL Notebook brings queries, interactive tables, charts, Markdown notes, and reusable inputs together in plain-text .sqlnb files. • Start with the included sample notebook or create your own. • Run queries against local SQLite and DuckDB databases. • Connect directly to PostgreSQL, DuckDB Quack, and Arrow Flight SQL servers. • Browse database schemas and inspect, sort, and copy query results. • Turn query results into charts and add Markdown explanations. • Add inputs to reuse a query with different values. • Import and share notebooks through Files. • Import a copy of a local database without changing the original. No SQL Notebook account is required. Notebooks stay in your local library, and saved database credentials are protected by the device Keychain. Remote connections send queries directly to the database service you choose. The app includes no advertising or usage-tracking SDK. Local SQLite and DuckDB queries work offline. Remote databases require network access and your own database credentials.
