Archived comparison
Gneta is no longer an alternative to TrainingPeaks.
The Gneta app has shut down, so a feature-by-feature sales comparison would be misleading. This page now points to the useful work that remains.
TrainingPeaks remains an active planning and coach-athlete platform. Gneta no longer offers plans, accounts or coaching.
The short answer
If you need an active training platform, choose an active product. Gneta is now a free research and tools publication.
