I wanted to control something we never had under control
If you go shopping/supermarket, and buy a lot of things, how do you handle tracking of the total cost? With a calculator, a special app, or just don't care about this at all - just take whatever you want and that's it?
I don t know if I m the only one like this, but I hope I m not
Usually, when I do grocery shopping, I heavily fail to spend what I initially planned. You take this, and this, and this it seems like you re still within budget, but at checkout it s almost always like What?! How did it get that much?
Cartculator - See your cart total in real time to avoid checkout surprise
Most shopping and budgeting apps assume you’ll type prices manually or only track spending after checkout.
Cartculator is the only shopping app that lets you see your total before checkout — just by scanning prices, not typing them.
You scan shelf prices with your phone and see your cart total in real time. No decimals, no mental math, no friction.
This removes the biggest reason people don’t track prices in the first place.
Plus, very comfortable, automatic list matching (planned vs taken).
