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 crypto profit 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

Enter your buy price, sell price (or the current price), and the amount you invested or the coin quantity. The tool returns gross and net profit/loss after exchange fees, your ROI percentage, and the break-even sell price.

Crypto prices move fast — this calculator uses the prices you enter, so figures are exactly as current as your inputs. Not financial advice.

Frequently asked questions

What is break-even price?
The sell price at which, after buy and sell fees, you get back exactly what you put in.
How are fees applied?
Fees are charged as a percentage of each trade's value — once when buying (reducing coins received) and once when selling (reducing proceeds).
What is DCA?
Dollar-cost averaging: buying a fixed amount regularly instead of timing the market. This tool evaluates a single buy–sell pair; repeat it per purchase to track a DCA position.

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).
