Today I released my first Android application, Tabata Trainer.
Developing this app has made learning Android development a very pleasant experience, while at the same time adding something new to the mobile ecosystem.

This app aims at providing a way for Tabata practitioners and general sports fans to do their exercises in an appropriate and automated timely manner. It also provides the ability for users to define/plan their own training exercises and times. More features are planned for next releases!

Tabata is a form of high-intensity interval training (HIIT) based on a study by Izumi Tabata. It initially consisted of one exercise carried out intensively during 20 seconds with 10 seconds of rest after it. This exercise was looped 8 times, giving a total of 4 minutes.

Summary of features:

• Tabata timer;
• Start/pause/stop controls;
• Definition of rest and exercise time;
• Definition of the number of rounds;
• Definition of any number of exercises, with textual descriptions, that form a custom training/workout;
• Text-to-speech engine to read exercises' names to guide users throughout their workouts;
• Sound alerts: Resting; Exercising; Darth Vader breath stimulator; Workout completed;
• English (UK) and Portuguese (Portugal) text languages supported;
• Text-to-speech in Portuguese is not available due to lack of support from Android;
• No ads and no special access permissions required;
• Sound, speech and display sleeping mode configurable;
• Ability to share current workout;
• Horizontal layout and Tablet support;
• Settings;
• Customizable sounds;
• Ability to disable the background gradient.

If you are willing to do some working out with this application, head over to the Tabata Trainer's Play Store page or Amazon Appstore and give it a try!
