One line, and a decimal
There is nowhere to put a numerator. Everything becomes brackets and slashes you have to hold in your head, and the answer arrives as a decimal you then convert back by hand.
Botple Calc
Maths that looks like maths.
Fractions stack. Powers sit up. Roots get a box for the index. You build the expression the way you would write it on paper — and the answer comes back as a fraction, not a decimal you have to convert.
Free. Works offline once loaded. No account, and it remembers nothing about you unless you ask it to.
Why the calculator on your phone isn’t enough
It was built to split a restaurant bill, so it flattens everything onto one line and hands back a decimal. That is fine for money and wrong for homework, where the answer your teacher wants is the fraction.
Stacked, and exact
Press the fraction key and you get a numerator box and a denominator box to type into. The result stays a fraction, so what you copy onto the page is the answer you were actually asked for.
What it actually does
A full scientific calculator that behaves like a notebook.
NOTATION
Boxes, not brackets
Fractions, powers and roots each open a real cell to type into — including the small box for a root’s index. You build the expression the shape it appears on the page.
EXACTNESS
Fractions stay fractions
Add a third to a sixth and you get a half — not a decimal you have to convert back. The exact form is the one that goes on your answer sheet.
MEMORY
Keeps your working
Every calculation stays in a history you can scroll back through and reuse, bookmark the ones you will need again, and store values into variables instead of retyping them.
OFFLINE
Installs, then stops needing the internet
Add it to your home screen or desktop and it opens like any other app. Once it has loaded once it keeps working with no connection at all — which is most of what a calculator needs to be.
This exists because the others wanted money
Botple Calc was built after one too many app stores turned a genuinely simple task — adding two fractions — into a countdown timer, a full-screen advert, or a subscription.
No adverts, full-screen or otherwise.
No subscription, and no trial that ends.
No account, and no sign-in wall in front of the keypad.
Nothing collected about you, so there is nothing to sell.

Botple Notes
Fill in a worksheet PDF by typing straight onto it. It finds the answer areas for you, works from a photo of a paper page, and never uploads your file.
What it does →MindSight
A reading comprehension tool built around real classroom-style passages and a debate-style way of checking understanding — not just multiple choice.
See what’s coming →Built by a student, in Malaysia
Botple is made by one student who got tired of study tools that cost money he did not have. Everything here is free because that was the point of building it.
