Notification Center for Pebble is an Android application developed by matejdro. This app replaces the native Pebble notification system and brings a range of new features. It can work with or without a custom watch app and offers extreme customizability, up to 20 custom canned responses, and enhanced notification filtering with regex and per-app ongoing toggle. Additionally, users can enjoy voice reply using their phone's mic or attached headphones, send notifications from Tasker, and execute Tasker tasks from notification actions. The app also supports RTL when paired with PebbleBits firmware and can replace characters that Pebble cannot display with those that can.

The custom watch app adds even more functionality, including configurable notification timeout, shake actions, per-app vibration pattern, and the ability to type replies from scratch on the Pebble. Users can view currently active notifications and perform actions on them, even if they have already closed the notification. A spam filter is also included.

Overall, Notification Center for Pebble is a feature-rich app that offers a lot of customization and convenience for Pebble users. However, it is important to read the permissions explanation, FAQ, and general documentation before installing the app. Please note that the developer no longer has a Pebble and will not be providing non-critical updates in the future.
