Thank you appreciate the support!
Hardline uses an AI model to analyze uploaded video clips of your training. It identifies the movement, grades it on six criteria, and provides specific cues to correct any faults.
Hardline supports eleven common calisthenics movements including pull-ups, push-ups, squats, pistol squats, muscle-ups, L-sits, handstands, handstand push-ups, front levers, back levers, and planches.
Your video is uploaded over an encrypted connection for analysis and is not stored by the app once the analysis is complete. Your original video remains in your device's photo library.
The app is free to download, but a subscription is required to produce new analyses. Existing verdicts remain accessible even if your subscription is inactive.
Hardline Premium offers auto-renewing subscriptions weekly, monthly, and annually. The annual plan includes a 3-day free trial for new subscribers.
You can manage or cancel your subscription by going to Settings > your name > Subscriptions on your device. Cancellations must be made at least 24 hours before the end of the current period.
No, Hardline analyzes video form and cannot detect physical pain or injuries. Always stop training if something hurts and consult a healthcare professional.
Clips must be between 3 seconds and 2 minutes, show the whole body in frame, have a clear view (side or front), and ideally only feature one person. The lighting should be in front of the performer.
