a Training Tracker (ANT+ BTLE)

About this app

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.

Ratings and reviews

App is not bad at all once you get the permissions set up on Android 10 to not kill it when the screen is turned off. I uninstalled in the end because it would not reliably pair with my HRM for some reason.

This is the only app that was able to connect to and receive data from my PowerTap Power Pro 2012 power hub, which automatically makes this app a win for me! Thank you so much. There are many issues with this app, but reviews are not the place to bring up faults. In my honest opinion, ignoring the bugs, this app is a must have and was the only one that worked for me and this is why I gave it a high rating.

this is awesome!! Thank you! I allmost bought garmin watch becaouse on my current watch HR sensor is not good. And I want to sync to Strava. Now I just bought cheap chest strap and connected it to this app. Luckily, I found a topic on the forum that mentioned you. Thank you for doing a great job!
