The Training Stopwatch is an application designed to meet the needs of coaches and athletes who seek precision and efficiency in monitoring performances in running sessions. This application allows for the management of multiple high-precision stopwatches, each dedicated to a specific athlete, enabling simultaneous recording of lap times (Laps) and intervals (Splits).
Main Features
Multiple Simultaneous Timers
- Ability to view up to four timers simultaneously, with the option to access additional timers through screen scrolling, making it easier to monitor multiple athletes at the same time.
- Support for up to 8 visible timers on tablets (coming soon).
Precision and Reliability
- The stopwatches synchronize with the device’s internal clock to ensure precision up to tens of microseconds, with the limitation only residing in the operator’s speed.
- Option to adjust the refresh rate of the displays to maximize precision without compromising usability.
Training Data Management
- Internal storage of all training data for each athlete, with an option to send this data by email and, in the future, via WhatsApp or other social media platforms.
- Functionality for planning training sessions with predefined laps and splits by the coach, allowing for more detailed and personalized preparation.
Flexibility and Customization
- Options to select measurement units (meters, kilometers, yards, miles) and calculate average speeds in m/s, km/h, yd/s, and mph.
- Customization of:
- Theme (light/dark),
- Language (Brazilian Portuguese, American English, Spanish),
- Stopwatch refresh interval, optimizing the experience on devices with varying hardware capabilities.
Simplified Interface
- Intuitive design with simplified activation buttons, highlighting only the essential functionalities for operation during training sessions.
- Ability to add and edit comments on training sessions, laps, and splits for detailed notes.
Individual Registration and Monitoring
- Registration of athletes with contact details such as email and phone, to facilitate the sending of results and feedback from training sessions.
Tutorial
To assist in using the application, an interactive tutorial has been added to the main screens, explaining its functionalities. The tutorial is available in all languages supported by the application.
The tutorial can be accessed via the menu icon when available on the screen. Below are some illustrative images.
Technical Considerations
For devices with more modest specifications, it is recommended to maintain the update interval around 0.5 seconds to ensure adequate interaction without affecting the smoothness of updates, avoiding delays that can impair the user experience in intensive use situations.
Future Expansions
This application is a prototype that seeks to expand further. It is planned to enrich the stopwatch management by including additional functionalities that meet the specific demands of coaches and athletes, increasing its usefulness and interactivity. Among the desired implementations are:
- Integration with Wearables: Connection with wearable devices for real-time data capture.
- Programmable Alerts and Reminders: Settings for hydration reminders and rest intervals.
- Voice Feedback: Customizable voice commands and audible feedback.
- Coach Mode: Dedicated interface for monitoring multiple athletes.
- Data Export and Import: Compatibility with sports analysis software.
- AI-Based Training Customization: Algorithms to suggest personalized training plans.
- Expanded Multilingual Support: Expansion of language options.
- Social Integration and Virtual Competitions: Virtual challenges to foster community.
- Advanced Performance Analysis: Detailed charts and visualizations.
- Training and Education Modules: Content provided by certified professionals.
