CleverNote raises the bar for Android notes apps.
As soon as you need more than just a shopping list, you will appreciate the thought and functionality that has gone into making CleverNote a best of breed app.
All notes are synced to Google Drive, so whether you're mobile or on your PC, your notes are where you need them, when you need them.
All notes are available offline. Always.
Notes can be created directly from the Notification Bar, and can "float" over other windows. This means that whatever else your device is doing, it's ready to take your notes too.
Oh... and it's free!
