Speed PRO is a GPS-based speedometer app developed by Mother Tucker LLC, offering a plethora of features for tracking your speed and activity. The app allows GPS and activity tracking, including step count, stairs ascended, and stairs descended. With options to save your tracks on iCloud or locally, you can edit your tracks by trimming unwanted portions. The app provides full-screen display of speed, average speed, top speed, distance, route time, altitude, and course, with features like pause/resume tracking, auto pause/resume, and orientation lock.

Speed PRO also offers camera features such as taking photos and recording videos by tapping or double-tapping, setting focus and exposure, and easy navigation between the camera and speedometer. Users can share snapshots on social media platforms and customize speedometer colors with built-in themes or a custom color picker.
