About Large Print Calculator
Helping Seniors and Visually Impaired Individuals Calculate with Ease Since 2026
Our Story
Sometimes the best ideas come from watching someone you love struggle.
That’s exactly what happened with our founder, Muhammad Shakeel Khan. One evening, he saw his 78-year-old father trying to pay bills online using his phone’s calculator. But the buttons were tiny. The numbers were blurry. His fingers kept pressing the wrong keys again and again.
His father got frustrated and said, “I can’t do this anymore.”
That moment stayed with Shakeel. He realized millions of seniors face the exact same problem every single day. The apps and tools we all use are not made for aging eyes or shaky hands. They’re made for young people with perfect vision and steady fingers.
So he decided to build something better. Something his father could actually use without asking for help.
That’s how Large Print Calculator was born.
Our Mission
We believe that accessibility is a right, not a privilege.
Our mission is simple: to provide free, easy-to-use, high-contrast online calculators that help seniors, visually impaired people, and anyone with motor difficulties do basic math with confidence.
No one should feel helpless just because they can’t see tiny buttons. No one should depend on others to add two numbers.We want every user to feel independent again.
What Makes Us Different
We don’t just make calculators; we build accessibility solutions. Every feature is designed with one question in mind: “Will this help a 70-year-old user?”
- Jumbo Buttons: Our buttons are 80 to 100 pixels tall—3 to 4 times larger than standard apps.
- Loud Voice Feedback: Every button press is spoken aloud (e.g., “One”, “Plus”).
- High Contrast: We use the doctor-recommended Yellow-on-Black color scheme for maximum visibility.
- Memory Functions: Pro-level memory features (MC, M+, M-, MR) simplified for daily budgeting.
- Clean Interface: A distraction-free layout designed to prevent cognitive overload.

We are not a big corporation. We don’t have investors breathing down our necks. We are just real people who built a tool for our parents and then decided to share it with the world.
