Great job on the app, I like how clean and elegant the UI is.
Here's my feedback, I think I'm using v4.
This needs to be able to be used as a task tracking app without any beeminder connection at all.
Get rid of the freebee limit.
Allow use without signing up.
Bugs or feature requests that cause me to not use the app:
Notifications - Argh.
Don't want notification on add, got two, less than 1 day & less than 1 hour.
Let me pick notification sound / vibration settings.
Remove date added from goal screen, or hide it.
Limited free tasks.
Done, where did my task go? I want to be able to see what I've done, and easily create tasks as copies of old ones.
Countdown wrong for tasks in the far future (more than a month.)
Goal list says am but date is pm.
Goal list shows time twice but no date.
Other feature requests:
Add app version number to UI somewhere
Show 24 hr time (respect system options)
Edit goal titles.
Add fine print/criteria/notes.
Empty first screen, maybe some text explaining you've got no goals.
Needs more help text about derailing.
Don't make default todo time "now" maybe now +15min
Make now+ time user configurable.
Tags for goals.
Watching goal derail, nothing happened.
Main screen menu button should open menu.
Ability to change pledge at task creation time.
Ability to increase pledge for existing goal.
Make it possible to change the due date. (Possibly subject to akrasia horizon)
Questions / things I've not tested:
What happens if you derail when you have no network connection?
Will the source code be available?
The bugs I found I'd class as minor and all my feature requests are probably things that other people wont care about. I think it's a great app, nice work.
