Why people use GenApps

Most tool websites upload your files to their servers, queue them, and sometimes keep copies. GenApps is built differently: every tool runs with JavaScript directly in your browser. Your passport photo, your PDF and your invoice data never leave your device — which is why the tools are instant, work on slow connections, and stay free.

The collection focuses on jobs people actually search for: compressing a photo to the exact kilobyte limit an application form demands (FPSC and PPSC want ≤30 KB, NADRA ≤50 KB), making a correctly sized passport photo at home, working out a loan EMI before visiting a bank, generating a GST-ready invoice, or checking a typing speed before a government job test.

Frequently asked questions

Are these tools really free?
Yes — every tool is free with no sign-up, no watermark and no daily limit. The site is supported by advertising, which is why we can keep file processing free.
Are my files uploaded anywhere?
No. Image compression, PDF merging, photo making and everything else happens locally in your browser. You can even disconnect from the internet after the page loads and the tools still work.
How accurate are the calculators?
They use the standard published formulas (reducing-balance EMI, compound interest, Naegele’s rule for due dates, Mifflin–St Jeor for calories) and show results to two decimals. They are planning estimates — for loans, taxes and health decisions, confirm final figures with your bank, tax authority or doctor.
Can I use these tools on my phone?
Yes. Every tool is mobile-first and works in any modern phone browser — useful when a form deadline hits and you only have your phone.

How to use the age difference calculator

  1. Enter your numbers in the fields above — use the exact figures from your loan, investment or bill for the most useful result.
  2. Press Calculate (most GenApps calculators also update as you type).
  3. Read the headline result together with the breakdown below it — totals, interest and schedules are shown, not just one number.
  4. Change any input and calculate again to compare scenarios side by side.

About this tool

Compare two birth dates to find the exact gap between two people — years, months and days — plus the total days apart and who is older.

A fun one to share: most siblings and couples are surprised by the exact day count.

Frequently asked questions

Can I compare more than ages?
The two dates can be any events — for example two siblings' births, or a parent and child — the tool simply measures the exact time between them.
Who is older?
The person with the earlier date of birth. The result states this clearly along with the gap.
Is the result exact to the day?
Yes, it counts calendar days including leap years.

Private by design

GenApps tools process everything locally in your web browser using JavaScript. Your files, photos and text are never uploaded to a server — close the tab and everything is gone. The only data our optional server features store is what you explicitly send us (a contact message, a tool rating or a newsletter email).
