Shake to delete!

April 29th, 2009 by Demian Turner

The latest update of the iPhone, available for the last few days now, has some fun features.  We went for more of the psychological angle and, following the advice of some Doris users in the forums, addressed the sense of satisfaction many people get when they tick off a task.

Until this release iPhone users had to resync their task list to get rid of items that were checked off.  This can be forced, by the way, either by hitting the History tab, or exiting and restarting the application.

But now we’ve added a feature that takes advantage of the iPhone’s accelerometer, to clear your completed Todos simply shake the phone!  We added the Mac “empty trashcan” sound to highlight the effect – try it out – quite addictive after a while.

Clearing all your completed tasks now feels like taking out the rubbish and starting with a clean slate.  Well, metaphorically at least ;-)

Other  new features in this release include:

  • swipe to delete a task or group: following the iPhone convention
  • data transfers have been compressed so you should see a speed increase
  • the ‘new group’ button was removed when you’re in Edit mode as the two actions are incompatible

Also be sure to try our ‘Disable sync’ feature on the settings screen.  With sync disabled the iPhone only attempts to sync with your online account when it’s in wifi mode.  This makes startup times and responsiveness much faster when you’re out and about.

    That’s great. Very satisfying.

    But I worry that apps using the accelerometer suck more battery juice. I’m not sure, but it’s seems like they would.

    A request for any network resource drains more battery power from the iPhone than checking values from the accelerometer. If you really want to optimise your battery life using Doris, just set the ’sync’ setting to ‘off’ – it will make a bigger difference.
