Objective:

To evaluate the effectiveness, usability, and impact of the mHealth app CoachMePlus (CM+) on Future Sailors' readiness for military life.

Approach:

Key Findings:

• 92.4% of FS successfully graduated from basic training.
• GMT scores improved from 51.7 to 67.9, and nutrition scores increased from 58.1 to 68.8 (p < 0.001).
• 64% of FS recorded dietary intake for at least 7 days, reporting lower fiber and higher fat and sodium intake than recommended.
• Over 80% of participants rated their self-efficacy for diet and exercise as 'rather certain' or 'very certain'.
• FS who completed basic training achieved a higher Recruit Division Commander assessment (p < 0.001).

Interpretation:

CM+ effectively monitored real-time achievements during DEP training, leading to improved military-related outcomes and nutrition understanding.

Limitations:

• The study was conducted in a single-arm intervention format without a control group.
• The sample size may limit the generalizability of the findings.

Conclusion:

The CM+ app is a valuable tool for enhancing the readiness of Future Sailors through improved nutrition and training.
