In their own words
dayGLANCE
dayGLANCE is a day planner built around a 24-hour drag-and-drop timeline for time-blocking. Schedule tasks on the timeline or keep unscheduled items in an inbox; the app also includes habits, recurring tasks, focus sessions, and calendar sync. The hosted web app requires no account and stores data locally in the browser by default. It works offline, with optional cloud sync for backup and access across devices. Calendar features include importing calendars and two-way task syncing with CalDAV lists. Tasks and notes can also sync through a user’s own Nextcloud or WebDAV server, and an Obsidian integration can read and write vault tasks and daily notes. dayGLANCE runs on Android, iOS, Linux, macOS, Windows, and the web, and can be self-hosted as a Docker image. The Android app adds a home-screen widget, background notifications, and optional Health Connect integration. Optional AI features use the user’s own API key. The software is MIT-licensed. The web app is free at free; dayGLANCE Pro is paid through the App Store, with no price listed.
Open Sunsama
Open Sunsama is a task manager and daily planner built around a board of days and calendar time blocking. Move tasks from a backlog to a daily board; unfinished work rolls over to tomorrow. Focus mode times a task and tracks actual time against its estimate. It syncs Google Calendar, Outlook, and iCloud, with support for multiple accounts. Time blocks stay in Open Sunsama rather than being copied to Google or Outlook calendars. Its hosted MCP server connects to Claude, ChatGPT, Cursor, and other MCP clients through OAuth and provides 24 tools. The REST API covers tasks, subtasks, and time blocks, with selectable API-key scopes. Users can also self-host the web app, API, MCP server, and PostgreSQL database using Docker Compose. The free plan costs nothing for personal use. The non-commercial license limits production use by companies, and there is no one-click export button. Desktop apps are available for Mac, Windows, and Linux; phones use the mobile web app, as no native phone app is available yet.
