✔ Sync with Google Calendar
Is there any better place to keep your tasks than the professional, ubiquitous, and free online calendar offered by Google?
Voodo syncs with a calendar called "Voodo" in your Google Calendar.
Sync is done non-intrusively - you can view or even edit tasks when sync is on the go.
With Auto Sync, your tasks are automatically synced to Google Calendar when added or modified. ㊎
Even if you quit Voodo during sync, it will complete in background.

✔ Local Alerts & Push Reminders
Besides local alerts, you can also get reminders for due tasks via Email or SMS, offered by Google Calendar for free.

✔ Tag, Tag, Tag
Lists/Folders complicate the hierarchy without good reason.
So I get rid of Lists/Folders, forgo the burdensome hierarchy, and build a really wonderful Tag system for you:
❖ Tag Tap Toggling
❖ Tag Input Hint
❖ Tag Filter
❖ Tag rename
❖ Tag merge
❖ Tag delete
❖ Tag clean

✔ Task Search & Quick Add
Task Search together with Tag Filter makes looking up a specific task a breeze.
And if you can't find it, Quick Add it.

✔ View it in your way
❖ Time Mode - if you concern which things are urgent.
❖ Calendar Mode - if your prefer viewing tasks on the traditional monthly calendar where you can also see events from the Calendar app. ㊎
❖ Priority Mode - if you concern which things are important.
❖ Location Mode - if you concern where to do these things.
❖ Nearby Mode - with Geo Locations, you can easily explore Nearby Tasks on map or distance-ordered list. ㊎
❖ Landscape Mode - for those who prefer landscape views.

✔ Every single bit and pixel is here to help you Get Things Done
Without bells and whistles, Voodo is built meticulously in the finest manner:
❖ Tap numbers to call, links to go, addresses to mail, in the Smart Note.
❖ What's better than the Smart Note if you just want to call up a friend? Contacts Integration.
❖ You can turn Note into a Subtask List - perfect for shopping lists! ㊎
❖ Not sure about the due time? Make it timeless.
❖ Just not want to be so rigid? Make it all-day.
❖ Recurring tasks? No problem, and they sync perfectly with recurring events in Google Calendar.
❖ Quick Actions help you quickly reschedule tasks. ㊎
❖ Want more privacy? Passcode Lock is for you. ㊎
❖ Want to delegate some tasks to someone else? Email them. And it's only one click to import received tasks to your Voodo. ㊎
