Smartwatch Pro for Pebble is a full-featured companion app for Pebble watches that adds a lot of additional functionality to your watch. Developed by Max Baeumle, Smartwatch Pro offers features like displaying upcoming calendar events, Twitter timeline, step count, and much more.

The app has won the "Best Technical Achievement" award at Pebble Developer RetreatThe app offers voice control (Twitter, Music, Reminders), calendar events with alarms, Twitter timeline with voice reply, retweet, and favorite options, step counter (requires iPhone 5s or later), reminders, location (address/coordinate, altitude, straight-line distance, speed), HTTP requests and status codes (GET/POST/…, for home automation, etc.), phone battery status, watch battery status, and find my phone feature.

However, some features like voice control and Twitter timeline require in-app purchases and Pebble 2 or Pebble Time. The app also allows users to share sleep analysis data from Morpheuz with the Health app. Please note that Smartwatch Pro requires a Pebble smartwatch and the Pebble iOS app.
