My Data Mine is another personal project developed by taking a Google Sheets spreadsheet and making it into a mobile app. The app is very simple. The current version of the app (1.1) has two parts:
- Vehicle stats: Collect vehicle stats for purchases with a specific focus on fuel costs and distance driven. The app displays stats and graphs of fuel efficiency and distance traveled over time.
- Data Mine: Collect customized data. The data mine lets you define the kinds of data that you collect. There are 3 basic types of data that you can collect: Numbers, Stings and List of strings (options/tags).
The app focuses on collecting data over time and displaying simple statistics about that data. The goal is to make data collection convenient and private.
About
There are four really important features of this app:
- It’s free.
- No ads.
- All your data is stored on the device (no external hosting).
- You can import and export your data (a text based format called JSON). There is an additional feature to import CSV data.
- You can delete your data (by uninstalling the app).
Why
I personally use the app. There are (likely) other apps out there that collect this kind of information so I (probably) didn’t have to write my own app, but I wanted to keep the information for myself. I also didn’t want to have an app with ads and I didn’t want to pay for an app. Why not stay with the spreadsheet? I’m tired of my spreadsheet and I wanted something more accessible.
The app also serves as a way for me to advertise my work.
