Measured after DeviceCheckHub went live on Zivaro Launch on 30 October 2026.
Day 3 since launch. Next receipt: day 30, 29 Nov 2026. These are measurements, not proof of cause: many things move these numbers. Figures we have not measured are left out.
Before any change goes live, an automated suite runs over 15,000 checks on the site in real browsers using simulated microphones, cameras and game controllers. The suite checks calculator answers against worked examples and tests pages at screen widths from 320 to 1280 pixels in light and dark mode. After going live, the same checks run again against the live site.
Calculators use published formulas and figures named on each page with links to the source, such as the CDC and World Health Organization for health measures, the IRS for US tax and retirement limits, and NOAA for sunrise, sunset and compass calculations. When a source updates its figures, the tool is updated to match.
No. The health and money calculators give estimates for general information only. They are not medical, financial or legal advice. For decisions about your health or money, you should talk to a doctor, a lender or a qualified adviser.
The tools are free and need no account. The site may show ads, and a few pages suggest a partner's product next to a clearly marked affiliate link as explained in the privacy policy. Neither ads nor partners decide what a tool says or which results it gives.
