About Joaquín
Joaquín Ríos is a Certified Personal Trainer and nutrition coach who has guided hundreds of clients in Buenos Aires through fat-loss and performance phases. At The Calorie Guardian he tests the parts of an app that decide whether people stick with it: accountability, coaching tone, and how targets respond to real training.
He runs each app through multi-week usage trials with synced wearables, checking whether calorie goals adjust sensibly to activity and whether the guidance motivates without shaming. He is especially sharp on apps that try to coach but get the tone wrong.
Joaquín also leads our wearable-integration testing across popular fitness trackers and smartwatches.
What Joaquín tests Runs multi-week adherence trials and tests wearable sync and adaptive targets.
