How can I contact support?

I recently purchased an annual subscription to Thelo and started a weight lifting program. I would like to move my rest days to be Fridays and Saturdays. How can I do this in the app? I wasn’t able to find a support contact.

FAQ

What does Thelo do?

Thelo is an AI personal trainer that uses a proprietary body scan technology to analyze your body fat, muscle balance, structure, and recovery. Based on this data, it creates personalized training plans that adapt as your body changes, offering a unique approach to fitness.

How does the body scan feature work?

The app uses a visual body scan to identify muscle imbalances, weak points, genetic structure, proportions, and areas that might be limiting growth or causing plateaus. It also assesses which muscles are recovered and ready for training.

Is Thelo a subscription service?

Payment is charged to your Apple ID upon confirmation. The subscription auto-renews unless canceled at least 24 hours before the current period ends. You can manage or cancel your subscription in your device's Apple ID settings.

What kind of progress can I track with Thelo?

Thelo helps you track meaningful progress beyond just weight. This includes daily body fat tracking, changes in body measurements over time, muscle-specific recovery insights, weight logging with a full history, and AI-guided progressive overload.

Who is Thelo designed for?

Thelo is for gym-goers tired of generic workout programs, individuals who feel stuck despite consistent training, and anyone who desires data-driven progress. It's particularly beneficial for lifters focused on physique, symmetry, and long-term fitness.
