About this app

aTrainingTracker is the best app for serious athletes who want every detail of their session recorded without the hassle of manual data entry.


No mandatory accounts. No registration. Full control. Start using the app immediately without a mandatory cloud account. Your training data belongs to you—and while your data stays on your device by default, most users choose to sync with Strava or upload the workouts to Dropbox to unlock the full potential of their performance analysis.


🏆 Master your Strava Segments Elevate your training with deep Strava integration designed for performance and strategy:
• Explore & Plan: Easily explore your starred segments before you even start. Study the segment and its elevation profile for every segment to plan your attack.
• Live Segment Detection: Your starred segments are detected on the fly, showing exactly where you stand from start to finish.
• Real-Time Timing: Track your segment progress live to know exactly how you’re performing against your goals.


📊 Universal Privacy Control You decide what the community sees. Configure your preferences once in the general settings:
• Granular Data Selection: Choose exactly which data streams are uploaded to Strava: Location, Altitude, Heart Rate, Power, or Cadence.
• Share only Location: Publish only your location to update the leaderboard but keep your power and heart rate for you.


🚀 Smart Automation & Training Zones
• Target Your Effort: Full support for Training Zones. Configure your specific zones for Running Heart Rate, Cycling Heart Rate, and Cycling Power to train with precision.
• Auto-Sport Detection: The app identifies your activity type (Run, Bike) based on your connected sensors.
• Equipment Tracking: Your bike or shoes are automatically assigned via sensor IDs, keeping your gear totals accurate without manual entry.


🔗 Unrivaled Sensor Support
• Multi-Protocol: Seamless support for ANT+ and Bluetooth LE sensors.
• Full Data Suite: Track Heart Rate, Power, Speed, Cadence, and even Temperature.
• Best Source Logic: The app intelligently selects the most accurate data source from all paired sensors.


📱 Fully Customizable Tracking
• Your Screen, Your Way: The tracking interface is fully configurable. Individually customize each view to show exactly the data you need while you are on the move.
• High-Contrast Interface: An efficient, clean UI designed for maximum readability during intense efforts.
• Instant Replay: Review your route and elevation profiles immediately after your session.


Simple Calibration. Forget complex math. To calibrate your sensors, simply input the measured and true distance, and the app does the rest.


aTrainingTracker turns your smartphone into a professional-grade training computer that respects your privacy and your performance.

Ratings and reviews

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.

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 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!
