Install this calculator

After install, it opens like a phone app, works without a signal, and keeps DA 5500 drafts on this device only.

1. Android Chrome: tap the menu (three dots) → Install app or Add to Home screen. That installs a WebAPK in the app drawer. It is the Android package for this calculator.
2. Samsung / Firefox: Home screen shortcut from the browser menu. Same offline app once the first load has cached.
3. Open the calculator once while online so the service worker can cache it. After that, height, waist, and DA 5500 PDFs work with airplane mode on.

Official DA Form 5500

The DA 5500 page stamps your tapes onto the JUL 2026 form. Download the filled PDF, print for wet-ink signatures, or copy the ATIS block. Signature lines stay blank. The form image caches for offline use.
