Predict - "Log your predictions" app

17th Aug 2015

As an exercise on programming Android, I've made an app to log predictions you make and keep score of your results. Like PredictionBook, but taking more of a personal daily exercise feel, in line with this post.

The "statistics" right now are only a score I copied from the old Credence calibration game, and a calibration bar chart.

I'm hoping for suggestionss for features and criticism on the app design.

Here's the link for the apk (v0.4), and here's the source code repository. You can download it at Google Play Store.

Pending/Possible/Requested Features:

Set check-in dates for predictions
Tags (and stats by tag)
Stats by timeframe
Beeminder integration
Trivia questions you can answer if you don't have any personal prediction to make
Ring pie chart to choose probability

Edit:

2015-08-26 - Fixed bug that broke on Android 5.0.2 (thanks Bobertron)

2015-08-28 - Change layout for landscape mode, and add a better icon

2015-08-31 -

Daily notifications
Buttons at the expanded-item-layout (ht dutchie)
Show points won/lost in the snackbar when a prediction is answered

I like it! Thoughts from 30 seconds of playing around:

There's some flickering in the text of the tabs while swiping between them.
What is the difference between a "Yes" and a "No" prediction?
Long presses are not particularly discoverable; perhaps there should be some buttons when you tap a prediction to expand it in the list view.

Design-wise, it's great apart from that. Both of your proposed features would be worthwhile too.

Thanks!

I'm not getting the flickering here... are you on a low-end device? Which version of android are you on?
No difference at all. I just thought it would make sense to phrase the predictions in the form of questions and answers - so you could e.g. pick a question from a pre-made list and just choose your answer.
Good to know, I thought "long press to edit" was a common enough pattern that everybody would discover it.
