Calíope — MySQL, MariaDB, Aurora & PostgreSQL Client Calíope is a powerful, native MySQL, MariaDB, Amazon Aurora and PostgreSQL client built for Mac, iPad and iPhone. Whether you're a developer, DBA, or data analyst, Calíope gives you everything you need to connect, query, explore, and manage your databases — all in a clean, native interface designed for Apple platforms. WHAT'S INCLUDED WITH CALÍOPE PRO SQL Editor — Write and execute queries with syntax highlighting and an integrated execution history, side by side across independent tabs, each with its own live session. Reports — A saved query with its parameters declared and its output defined: which columns, in what order, with what titles and formats. Running it twice gives the same thing. Works against relational databases, SQLite files and MongoDB, exports to nine formats including a paginated PDF, and can run on a schedule. Database Explorer — Browse your full schema — tables, views, stored procedures, triggers, events and more — from an intuitive tree, with columns, indexes and foreign keys at a glance. ER Diagrams — Visualize your database structure with interactive entity-relationship diagrams. Understand table relationships and schema design without writing a single query. Secure Connections — Connect to remote servers safely with native SSH tunneling (ed25519 and ECDSA keys), SSL/TLS encryption, and per-profile credential storage in your system Keychain. Scheduled Backups — Automate backups with flexible scheduling and configurable retention, choosing exactly which databases and tables go into each job. Replication Topology — Declare the primary and its replicas, and see the whole group at once, with a diagram: each replica with its lag, its two threads and the transactions it actually owes. A replica can report 0 seconds while it runs hours behind. Multiple Sessions & Query Log — Open and switch between independent database sessions, each isolated. Every query is logged locally, so you can trace what was executed, when, and on which connection. Works without a server — A built-in SQLite editor for local .sqlite files: structure, data, SQL, pragmas, Save/Revert and CSV/JSON/SQL import and export. Plus a read-only previewer for .md, .sql, .json, .csv, .rtf and .log files. Both work offline. Widgets — Server metrics without opening the app: Mac desktop, iPhone and iPad Home and Lock Screens. One server per widget; tap to open its dashboard. AI SQL Assistant — An optional assistant that helps you write queries, explain results and suggest optimizations. It works from the first launch with Apple Intelligence: no key, no cost, and nothing leaves your device. You can also bring your own key from a supported provider — usage is billed by that provider, and Calíope does not charge for or resell AI services — or point it at a local model. Keys stay in your Keychain. ONE-TIME PURCHASE • Calíope Pro — buy once, keep forever.

And before you decide, 60 days free with everything unlocked. What's new: • One payment, forever — Calíope is no longer a subscription. Buy it once, use it on every device, and get every future update. And before you decide, 60 days free with everything unlocked. • One Calíope, on every device — Calíope no longer has one App Store page per device. The same page installs it everywhere, and one purchase covers all of them. What you already bought still counts: the purchase belongs to the app, not to the platform, so nothing is charged twice. • An assistant with no key, and Calíope as a tool for your AI — The assistant works from the first launch with Apple Intelligence: no key, no cost, and nothing leaves the device. If you prefer a local model, Ollama works too. And on the Mac, Calíope can be a tool for Claude Desktop or Cursor over MCP: read-only, only the connections you tick, only while the app is open. • Slow queries — Calíope reads what your server already wrote down about the queries that took too long, from every client that connects to it and not only from Calíope. From the same screen you turn the log on, move the threshold and empty it, and one button sends the query to the editor, where the profiler already is. Each engine in its own vocabulary: the slow log and the per-statement summary on MySQL and MariaDB, pg_stat_statements on PostgreSQL, and read-only settings on Aurora, where they live in the cluster's parameter group. An empty list is never the answer: if the log goes to a file on the server's machine, if the summary is switched off or if the extension is not created in that database, that exact reason is on screen. • MongoDB profiler — The same question in MongoDB's own words, and a tool of its own because the profiler is per database. Turn it on for the database you are looking at, set how many milliseconds count as slow, and read what it recorded with the sample rate the server is actually using. Emptying it turns the profiler off, drops the collection and puts the level back. Requirements: Calíope 1.4 needs macOS 26 Tahoe or iPadOS 26. On an earlier system, version 1.2 stays available and keeps working. ### 1.2.0 — 2026-08-13 Calíope 1.2 — Redesigned and more accessible Version 1.2 rethinks how you move around Calíope and takes a big step forward in accessibility, on both Mac and iPad. What's new: • New navigation — The left sidebar is now a launcher for all 23 tools, always at hand, and the database/table tree lives right inside the SQL editor, where you actually use it. You can collapse it, and long names now wrap so you can read them in full. • Accessibility — A step toward better accessibility compliance: a native dark interface that follows your system appearance, support for Reduce Motion and Reduce Transparency, improved contrast in the common views, status shown with icons and text (not color alone), and more keyboard shortcuts on Mac. We're still refining VoiceOver and larger text (Dynamic Type) and will expand them in upcoming updates. • A more native interface — Many views were rewritten with native components for a cleaner look and full parity between Mac and iPad. • Amazon Aurora — Amazon Aurora is now an explicit server type. Aurora speaks the MySQL protocol, so you connect with the MySQL-compatible features. • SQLite Editor — A self-contained tool for local SQLite files (.sqlite, .db): structure, data, Execute SQL and pragmas, with Save/Revert changes and CSV, JSON and SQL import and export. No server needed. • File Previewer — Read .md, .sql, .json, .csv, .rtf and .log files in read-only mode: Markdown renders as a document, SQL gets syntax highlighting and line numbers, JSON is re-indented, CSV is shown as a table, RTF keeps its structure and emphasis, and the view refreshes on its own when the file changes on disk. It works with no connection, and nothing is ever executed. • Keep Awake — A toggle in the toolbar that stops your Mac from going to sleep while a long backup, import or query is running. Turn it on and off yourself; it never expires on its own, and the status stays visible so you don't leave it on by mistake. Optionally it can also keep the display on. On iPad it keeps the screen awake while Calíope is in the foreground. • MongoDB — A new tool for document databases: browse collections and documents, edit them as JSON, write filters and aggregation pipelines, manage indexes, and check the server, its running operations and its users. Every value shows its type (ObjectId, decimal128, dates, binaries), because a collection has no schema. • Global search and replace — Search one text across every table in a database and replace it, with a preview of each change and a warning when search and replace do not count the same (case sensitivity). • Spatial data — GEOMETRY columns are drawn on a map inside the SQL editor: drag a point or a vertex and Calíope proposes the statement, which never runs until you accept it. • Settings backup — Export and import your connections and preferences, with a restore point taken before every risky operation. Secrets are encrypted and only included if you ask. • Error log — App failures are recorded with an explanation and a link to the help, and can be read with no connection. • Large backups — Backing up and restoring multi-gigabyte databases no longer depends on available memory. • Alternate host — Every connection can now have a second address. If the main one doesn't answer, Calíope tries the alternate with the same port and credentials — useful when the same server is reached one way from your Mac and another from your iPad. Plus the usual translation updates, security hardening, help improvements, and bug fixes. Thank you for using Calíope! ### 1.1.0 — 2026-07-31 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
