Frequently Asked Questions

How does Jacked calculate my suggested weight?

Jacked uses a Kalman filter-based algorithm that learns from every set you log. It tracks your estimated 1RM for each exercise and uses your target reps and RIR (Reps In Reserve) to calculate the optimal working weight. The more you train, the more accurate the suggestions become.

What is RIR and why does it matter?

RIR stands for "Reps In Reserve" - how many more reps you could have done before failure. Training at RIR 1-3 (1-3 reps from failure) is the sweet spot for hypertrophy: challenging enough to stimulate growth, but not so hard that it impairs recovery. Jacked tracks your RIR to optimize your training intensity.

How does volume tracking work?

Jacked counts "hard sets" - sets performed at RIR 3 or lower - for each muscle group. It compares your weekly volume against personalized targets based on your training age and goals. The targets are based on research showing the minimum effective volume (MEV) and maximum recoverable volume (MRV) for muscle growth.

My data isn't syncing between devices. What should I do?

Jacked uses iCloud to sync your data. Make sure you're signed into the same iCloud account on both devices and that iCloud Drive is enabled for Jacked in Settings > [Your Name] > iCloud > Apps Using iCloud. Give it a few minutes after making changes - syncing can sometimes take a moment.

Can I import my workout history from another app?

Yes! Jacked supports importing workout history from Hevy. Go to Settings > Import History and follow the instructions. Your historical data will be used to calibrate Jacked's predictions for your exercises.

How do I request a refund?

Refunds are handled by Apple. You can request a refund through the App Store by going to reportaproblem.apple.com, signing in with your Apple ID, and selecting the purchase you'd like to refund.
