Health & Fitness Disclaimer
CutEngine is a fitness tracking and nutrition planning tool designed to assist with fat loss phases. CardioEngine is a heart rate zone coaching tool designed to guide cardiovascular training. Neither app is a medical device, is FDA-approved, or provides medical advice, diagnosis, or treatment.
The calorie targets, macro recommendations, body fat estimates, recovery scores, heart rate zone thresholds, and training recommendations provided by our Apps are calculated using general formulas and algorithms. They are estimates and may not be accurate for all individuals.
Before using our Apps:
- Consult with a qualified healthcare provider before starting any diet, exercise, or weight loss program.
- If you have a medical condition, take medications, or have concerns about your health, seek professional medical advice.
- If you have a heart condition, consult your cardiologist before using CardioEngine or any heart rate zone training program.
- Do not use our Apps as a substitute for professional medical advice or treatment.
Body Composition Estimates (CutEngine)
Body fat percentages calculated using the Navy Method (tape measurements) and skin calipers are estimates with inherent margins of error (typically 1.5–3% compared to DEXA scanning). These estimates should not be used for medical purposes.
DEXA scan data imported from BodySpec is provided by BodySpec and is subject to their accuracy standards. CutEngine is not responsible for the accuracy of third-party scan results.
Heart Rate Zone Accuracy (CardioEngine)
Heart rate zone thresholds calculated by CardioEngine are based on general population models (e.g., percentage of estimated max HR, aerobic threshold estimates). These are approximations and may not reflect your true physiological zones.
- For the most accurate zone thresholds, consider a lab-based VO2max or lactate threshold test.
- Heart rate readings depend on the accuracy of your connected device (Apple Watch, BLE chest strap). Sensor placement, motion artifacts, and device quality affect accuracy.
- CardioEngine is not responsible for inaccurate readings from third-party heart rate monitors.
- Zone coaching is guidance, not a prescription. Adjust your effort based on how you feel.
BLE Device Compatibility (CardioEngine)
CardioEngine connects to Bluetooth Low Energy heart rate monitors using standard BLE Heart Rate Service profiles. Not all BLE devices are guaranteed to be compatible. We do not manufacture, endorse, or guarantee any specific heart rate monitor hardware.
Enhancement Tier Information (CutEngine)
CutEngine includes options for users who take performance-enhancing substances (TRT, GLP-1 agonists, peptides, etc.). This feature adjusts deficit recommendations based on general fitness community guidelines. This is not medical advice regarding pharmaceutical use. Always consult your prescribing physician regarding any substances you take.
Caliper Calibration (CutEngine)
When DEXA scan data is used to calibrate daily caliper measurements, the resulting calibration offset is an approximation. Calibration accuracy depends on measurement consistency and may drift over time.
Machine Learning Recommendations (CutEngine)
CutEngine uses machine learning algorithms to adjust calorie targets. These adjustments are based on patterns in your data and are not guaranteed to produce specific results. Individual responses to dietary changes vary significantly.
No Guarantee of Results
Our Apps do not guarantee any specific weight loss, body composition, cardiovascular fitness, or health results. Results depend on many factors including genetics, adherence, sleep, stress, and other variables outside the apps' control.
Third-Party Products
CutEngine provides links to third-party products (AccuMeasure calipers, MyoTape body tape measure) for convenience. CardioEngine may reference third-party heart rate monitors. We are not affiliated with these manufacturers and do not guarantee their products. Product links are not affiliate links.
App Store Disclaimer
CutEngine and CardioEngine are not developed by, endorsed by, or affiliated with Apple Inc. Apple is not responsible for the content or functionality of our Apps.
Limitation of Liability
Use our Apps at your own risk. Feeling Mindful Labs LLC is not liable for any injury, health issue, or adverse outcome that may result from following recommendations provided by the apps.
