It started as a hobby project to solve my personal needs: I really hate grocery shopping: it's repetitive and takes time. I decided to automate it, but couldn't find any robust tools for that. Also for a long time wanted to create a parser and this was a good opportunity.
Current plan is to offer iOS and Android apps for a one-time fee. These apps are based on open-source language and parser (the same used by CLI), but a bit nicer and user friendlier.
