A calculator that can deal with distributions ergonomically, to allow users to easily arrive at fermi estimates that incorporate uncertainty.
A calculator app for distributions on Android
About
This is a calculator app for Android that can deal with distributions. It looks as follows:
The idea is to have a simple app that is able to help people operate with distributions quicker.
Getting started
Download F-Droid, an alternative to Google Play for open source apps, then download the distribution calculator from F-Droid. This has the advantage that F-Droid will take care of updates, scanning, etc. Installing F-Droid also means that you can download other cool F-Droid apps.
Alternatively, you can download the apk from Github releases here. Google may ask you to scan it, it doesn't take that long.
Usage
- Try examples from this thread!
- See an introduction to Fermi estimates here
- Swipe left or right to duplicate an input
- inputs and outputs represent the 90% confidence interval (5% to 90%).
Contributions
Contributions are welcome. Feel free to make a pull request, e.g., adapting this app so that it also works on your phone, adding more error checking, etc.
