Sunsama is a mobile app that helps you stay organized and productive on the go. It is a companion app to the desktop version, which means you need to plan your day on the desktop app before using it. Once you have planned your day on the desktop app, you can use the mobile app to stay in sync when you're away from your desk.

With Sunsama, you can quickly add new tasks to your list, schedule them on your calendar, and move them to the right spot on your list to work on them later. You can also review your plan for the day and create a calm, focused space to stay on top of your workload. The app is synced with Google Calendar and Outlook Calendar, so you can browse both your tasks and calendar events each day.

Overall, Sunsama is a great app for those who want to stay organized and productive while on the go. However, keep in mind that it is not a standalone app and you need to plan your day on the desktop version before using it.
