Slow Speed
Read full descriptionHide full description
Research shows that physical activity is important. This app encourages individuals at an increased risk of developing Parkinson's disease to move more. The app will set weekly goals, and your steps and heart rate will be measured to monitor your progress. A virtual coach will stimulate and support you throughout this process. NOTE: The Slow Speed app is exclusively meant for participants in the research study conducted by Radboud university medical center (Radboudumc). If you are not participating in this study, you will not be able to use the app. For more information, refer to: https://www.parkinsonopmaat.nl/parkinson-vraagbaak/slow-speed

Verdict
The clearest difference is in-app purchases: Slow Speed at none against TRMR AI's 1. Slow Speed also leads on iOS requirement (13.4 vs 15.0). TRMR AI's advantage is update cadence (every 6 weeks vs every 5 months). On price, ads and device support there is nothing between them.
