a Training Tracker

aTrainingTracker: The serious athlete's tracking cockpit.

aTrainingTracker is a sports tracking application designed for athletes who demand precision and automation. While focusing on a solid tracking experience during your session, the app also includes tools for basic aftermath analysis and long-term volume tracking. By leveraging multi-sensor connectivity (ANT+ and Bluetooth LE), it transforms your smartphone into a professional training computer.

FOCUSED ON PERFORMANCE, MINIMIZE INTERACTION

For those who want to track every detail of their training without wasting time on their phone:

• Zero-Touch Automation: Once configured, just press Start. The app automagically determines the sport (Run/Bike) and the specific equipment (bike or shoes) based on the remote sensors detected.

• Best-Sensor Logic: Intelligent priority system selects the highest quality data source (e.g., preferring dedicated ANT+ or BTLE speed sensors over GPS-based speed for superior precision).

• Cloud Ready: Automatic synchronization with Strava and Dropbox. Your data is ready for analysis on your computer (WKO+, Golden Cheetah) by the time you've finished your post-workout shower.

• Privacy First: All tracked data is stored exclusively on your device (unless you choose to upload it to the cloud). I do not collect, store, or have access to your personal workout data.

MAIN FEATURES

• Extensive Sensor Support:

• ANT+: Heart Rate, Speed, Cadence, Power Meters, and Temperature.

• Bluetooth LE: Heart Rate, Cycling Speed/Cadence, Running Speed/Cadence.

• Multi-Sensor Pairing: Pair unlimited sensors; the app automatically connects to what is available when you start.

• Highly Customizable Cockpits: Build your perfect dashboard with multiple configurable, sport-type dependent views. See the exact metrics relevant to your current activity.

• Versatile Export: Support for TCX, GPX, CSV, and Golden Cheetah formats.

• Social Sharing: Generate professional workout snapshots combining your map, elevation profile, and key metrics into a single image.

• Navigation & Routes: Import routes from GPX or the Strava server and follow them on the live map during your session.

• Strava Segments: Manage starred segments with detailed metrics and elevation profiles. Enjoy real-time detection and live feedback while on the segment.

• Training History: Simple built-in summaries (weekly, monthly, yearly) to monitor your training volume at a glance.

A 25-YEAR JOURNEY

This project began as a vision over two decades ago. Back then, I was an engineering student exploring mobile coding with Java Midlets. I dreamt of a future where the mobile phone—with its storage, display, and computational power—could act as the ultimate training log, gathering data from remote sensors.

I transitioned from a casual jogger to a passionate triathlete, and when the first ANT+ smartphones arrived in 2011, I was ready. I bought one immediately but found no apps powerful or automated enough for a serious athlete. So, I started coding.

After a lengthy break between 2019 and 2025, I returned with renewed energy, modernizing the UI while keeping the solid core tracking logic intact. It is a labor of love, and I am proud to share it with you.
