SeaBag
Navy Calculators & References
Free · Designed for iPad. Not verified for macOS.
SeaBag is the offline-first Navy reference app built for U.S. Navy Sailors. Search messages, check references, run calculators, and keep key career tools close — even when signal is weak or unavailable.
NAVADMIN & ALNAV SEARCH
Search and read Navy Administrative Messages and ALNAVs by number, keyword, subject, or full message text. Open any message, search inside it, and quickly find the section that matters. SeaBag also includes readable summaries to help you get the key points faster.
PUSH NOTIFICATIONS
Get notified when new NAVADMIN or ALNAV messages are released. SeaBag syncs new messages when available, then keeps them ready for offline use.
OFFLINE REFERENCES
Browse practical Navy references without needing a browser tab or reliable connection:
• MILPERSMAN — Search and browse Navy personnel manual articles
• UCMJ — Full Uniform Code of Military Justice reference
• Uniform Regulations — Covers, grooming, wear standards, and visual guidance
• Correspondence Guide — Quick help for Navy letters, memos, formatting, and routing
• Physical Readiness Guides — PFA, BCA, waivers, FEP, PRIMS, command responsibilities, and related readiness references
ACRONYM DECODER
Look up common Navy acronyms and terms offline. Useful for new Sailors, cross-rate work, admin tasks, and reading official messages faster.
CALCULATORS & TOOLS
Use practical calculators and quick-reference tools built around everyday Navy needs:
• BAH — Basic Allowance for Housing by ZIP code, dependency status, and pay grade
• Pay Charts — Active duty base pay by rank and years of service
• PFA Standards — Physical Fitness Assessment pass/fail thresholds by age group
• BCA Standards — Body Composition Assessment support
• Advancement / FMS tools and other career-planning utilities

BRAG SHEET
Build and export a clean service record summary with awards, qualifications, education, commands, and other career highlights. Sync across devices with Google Drive.
TODAY IN NAVAL HISTORY
Read daily naval history articles with source-linked context and offline-friendly access after sync.
OFFLINE FIRST
SeaBag is designed for ships, duty sections, travel, and low-connectivity environments. Sync when you have a connection; use your references, calculators, and saved data when you do not.
SeaBag is independently built and is not affiliated with, sponsored by, or endorsed by the U.S. Navy, Department of Defense, or any government agency. Always verify official requirements against the current source publication or command guidance.
