Useful, not overwhelming.

EveryCalc V1 contains 60 focused calculators and utilities, plus 15 device and connection tests. Closely related tasks share a tool. Conversions live in one workspace instead of hundreds of duplicate pages.

Transparent results

Formulas and assumptions are displayed with each calculator. Input values are processed locally. Financial tools use the rates you enter, not live lending or tax rules. Health tools provide adult educational estimates, not diagnoses or personal treatment plans.

What the tests measure

Speed tests use single-stream HTTP transfers. Ping means HTTP response time, not ICMP. Jitter is the average difference between successive HTTP response times. Refresh rate means observed browser frame cadence. Physical pixel and audio tests require your observation.

Deliberate V1 limits

True packet loss, live currency conversion, public IP/DNS lookups, specialist construction tools, and the extended developer catalog are not part of this 75-tool release. CVSS uses v3.1 Base metrics, not v4.0. Tax take-home pay uses a manually supplied effective rate. GPA conversion policies vary by institution.

Privacy and accessibility

No advertising trackers or account registration are added by EveryCalc. Device access begins only with your action and permission. Motion respects reduced-motion settings. The site supports keyboard navigation and light/dark themes.
