tldr; get the new Fatebook Android app!
What is Fatebook?
Fatebook.io is a website[1] for easily tracking your predictions and becoming better calibrated at them. I like it a lot, and find it convenient for practicing probabilistic thinking.
That said, I've found Fatebook's mobile version to be clunky, and its email-based notifications to be less-than-ideal...which leads me to:
The New Android App
Over the past two weeks, I've made an android app that wraps the Fatebook API, allowing you to easily make new forecasts, leave comments, resolve old forecasts, and view your stats.

A beautiful and intuitive UI combined with a fast offline-first database makes it easy pull open the app and log a prediction within fifteen seconds of thinking of one, while once-daily "remember to predict!" and "x is ready to resolve!" notifications help you remember to make and review new predictions.
Give it a try if you'd like![2]

Feedback or development help is very much appreciated! (so far it's just been Claude Code and I)

Made by the fabulous folks over at Sage Future, also behind the AI Village, Quantified Intuitions, and the Estimation Game!

It does currently require installing from the GitHub Releases APK file (aka enabling "Install from unknown sources"). Let me know if being non-Google Play Store is a deal breaker for you and I'll bump getting it published in priority!
