README
CalcPad is a different take on the calculator.
Runs on linux, mac, and windows.
# Installation
Download the [latest release](https://github.com/filipesabella/CalcPad/releases/latest) for your platform.
## Web version
There's a slightly simpler web version [here](http://filipesabella.com/CalcPad/).
It doesn't do any kind of file handling or http requests, as everything is stored using the browser's LocalStorage.
It works ok on phones, and you can install it as a PWA.
### Self-hosting the web version
Since the app is fully offline, you can simply either download the latest [built files](https://github.com/filipesabella/CalcPad/tree/build/docs), or build them yourself with `npm build-web` - the files will be in the `docs/` directory.
Alternatively you can use shmup's [redbean](https://github.com/shmup/redbean-calcpad) build.
