User Reviews

Users praise the app for its effective gradual training plans and support in preparing for half marathons, with motivating voice guidance. However, many face significant issues with the transition to a subscription model, causing loss of access despite prior purchases. Technical problems such as app crashes during runs, inaccurate mileage tracking, and missing features like watch support frustrate users. Customer support is often unresponsive or ineffective in resolving these problems, leading to dissatisfaction despite otherwise effective training content.

Pros

Provides a scientific and gradual training schedule that builds endurance effectively.
App has helped many users successfully complete half marathons and achieve running goals.
The audio coaching feature with live voice guidance during runs is appreciated.
Previous versions (like C25K and 10k Trainer) are highly regarded and life-changing for users.
Customer support has at times been responsive and helpful with subscription issues.

Cons

Subscription model implemented after initial purchase, causing users to pay again or lose access, especially when changing phones.
App crashes or closes unexpectedly during runs, resulting in lost tracking progress.
Lack of features such as smartwatch support and the inability to review past runs or adjust settings like beep/custom audio notifications.
Inconsistent and inaccurate mileage tracking, making it unreliable for personal records.
Poor customer support, including undeliverable email addresses and unresponsive communication for resolving subscription and access issues.
