In their own words
Align
Align is an iPhone planner that combines tasks and calendar events in a visual time-blocked schedule. Users can drag or resize blocks, set alerts when blocks start or reminders in advance, and add checklist subtasks. Completing every subtask marks the parent block finished. Blocks can repeat daily, weekly, monthly, or yearly, and Align imports events from calendars available through the device’s iOS calendar system. Align Plus can move later blocks while preserving their duration. The free plan includes unlimited time blocks, calendar sync, recurring blocks, reminders, colors, icons, and drag-and-drop planning. Plus is an optional in-app subscription or one-time purchase, with weekly, monthly, yearly, and lifetime options listed; prices appear in the App Store. Align requires iOS 17 or later. It runs on iPad in iPhone compatibility mode, while other Apple platforms are not supported today. The maker says data is stored locally or synced to a private iCloud account and that it does not collect, share, or sell personal data.
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.
