About this app

Libellus helps you organize your daily life and recover valuable time for what you care about. You can plan schedules and receive precise reminders for every activity. Create focus timers with a single tap and avoid distractions. Libellus is free and with no ads.

# Features

## Focus timer ("The Watcher")
Based on the Parkinson's Law and Pomodoro technique, the Watcher shows a full-screen countdown timer to generate the urge to complete a task. Every activity generates a timer visible via the Watcher and background notification, so you don't have to open the app to stay productive.

Parkinson's Law states that one will always prolong a task to use all the time available before a deadline. Trick your mind into tightening those deadlines and forcing yourself to use the minimum amount of time to complete an activity.

## Timeline
Our timeline view supports a time-block builder interface for adding activities in "chunks" to speed up the schedule creation process. Moreover, Libellus auto-saves your activities on the cloud and synchronizes data across your devices.

## Notifications
Libellus sends reminders as background notifications to keep up with your schedule. These notifications include a countdown timer, visible on lock screens, and paired smartwatches.

## Statistics
Review your daily and weekly time metrics.

## Customization
Tweak the following app settings: notifications, time format, theme, language (English and Spanish only, by now), Timeline grid, custom name in timer for activity gaps, preferred schedule start time, and data management.
