About Daily Army

Daily Army is a collection of free, fast, ad-supported utility tools. Each tool lives on its own subdomain, loads in under a second, and requires no account, no signup, and no tracking cookies.

The tools

• BTU ↔ kW Converter — convert HVAC capacity ratings between BTU and kilowatts
• Mortgage Amortization Calculator — full payment schedule and total interest
• Currency Cross-Rate Calculator — 10-currency grid using live rates
• Running Pace Calculator — pace, time, or distance for any race
• US ZIP Code to Time Zone — timezone and UTC offset for any US ZIP

How it's built

Every tool is a static Astro site — no server-side rendering, no JavaScript framework runtime. Pages are pre-built and served from edge CDN. Total page weight is under 30 KB per tool.

Analytics

This site uses no client-side analytics, no Google Analytics, no tracking pixels. Traffic is measured by parsing server-side access logs only — no cookies, no beacons, no GDPR exposure.

Advertising

Tools are free because they run Google AdSense display ads. Ad space is reserved at page-load time so there's no layout shift. No autoplay audio, no pop-ups, no interstitials.
