We've been provided a heads up that Effectual for Windows Phone will be updated in the next handful of days. This upcoming release will add auto-suggest and spellchecking functionality, which is something we picked up in our previous coverage. What's more is the team has other features on its list for future versions.
Here's a quick snippet of the response a reader of ours received from the Effectual team:
"We have gotten several requests for the ability to set reminders for a specific time of day, rather than just on a date. It is definitely on our Effectual to-do list!"
As noted above, the next version of Effectual should be available in the next few days (depending on store approval speed). You can download Effectual from the Windows Phone Store (Windows Phone 8 only). Thanks, Alan, for the tip!
