About Web4pps
Web4pps is a site of free calculators, converters, and small utilities that run in the browser, plus articles that explain how the numbers work. It is operated by Neil Anthony Te through Atomic Devs Software. There is no account to create. Most tools keep your inputs on your device.
Philippine finance tools (SSS, Pag-IBIG MP2, 13th month pay, electricity cost, and similar calculators) follow published formulas and official contribution or rate tables where those exist. Health and fitness estimates use standard public formulas such as WHO BMI cutoffs and Mifflin–St Jeor. Results are for planning and education. They are not legal, tax, medical, or investment advice.
What is on the site
- Browser tools — calculators and utilities with the method, limits, and a short privacy note on each page.
- Articles — notes that sit next to those tools, including personal finance and how a calculation behaves in practice.
Who runs it
