Tried to write my own home inventory management app. This means I have to start learning how to program in Android *properly* (I mean a good enough architecture, like MVVM or something else, not just "good enough to work").
When I was headache about how to start, I accidentally found an app called Memento Database, which is a pretty flex app that allows you to create your own tables and link them. They also support Data Matrix (a 2d barcode). And I found out it can perfectly solve my need.
It's basically free and if I want, I can pay them 5 USD per month for the cloud backup things.
Maybe I will try to write an Android app as a side project? Considering I have a thermal printer to work with.
