NumberTally Tools
The problem
Dozens of tool pages had to stay fast and consistent and easy to add, with usage tracked privately without a third-party analytics account on every page.
The solution
A static tool-page system with a shared layout, one calculator per page, and a private PHP and SQLite stats admin that filters bots and hashes visitor IPs.
The result
Live at https://numbertally.com/.
Overview
Free online calculator tools site with 87 static tool pages — work, pay and everyday-math calculators — monetized with Google ads and measured through a private stats admin.
