Description
AI generated by Codex for Uri Bogat. An original advertising arithmetic calculator with a dark connected ring interface and a vertical phone flow. Enter impressions, clicks, conversions, USD spend and reported revenue. View click through rate, conversion rate per click, CPM, CPC, cost per conversion, revenue per conversion and revenue divided by ad spend. Zero denominators show Unavailable, and inconsistent counts block results. Includes a readable report and validated JSON backups. This simple funnel allows at most one conversion per click. No account connection, attribution model, statistical significance, profit calculation or performance forecast.
Editor contents remain in this tab only, on both the hosted demo and standalone source. Export a JSON backup to keep them. No contents are automatically written to browser storage.
Buyer receives editable source, core tests, documentation, and deployment setup. Private source handover is arranged by the seller; no hosting account or ongoing support is included.

Setup requirements
Unzip source and run python3 -m http.server 8080 in the folder. Open http://localhost:8080 or deploy to a static HTTPS host. No build or API key. Node 20+ runs test.mjs. See README.md and QA.md.
Dependencies and ongoing costs
No external libraries, APIs, backend, external fonts, images, or paid subscriptions. Hosted demo is served by SellMyVibe. Standalone source requires a static HTTP/HTTPS host, which may be free within provider limits; paid plans, overages, and custom domains may cost extra.
Known limitations
Working prototype. No live ad accounts, causal attribution, statistical significance or forecasting. Simple funnel assumes at most one conversion per click; not a multi event attribution model. ROAS is revenue divided by ad spend, not profit; entered figures are unverified. App data resets on reload in the hosted demo; export JSON backups. See the app description for standalone storage behavior. No independent security audit or broad device/browser certification.
