Need a personal assistant to make sure you never forget a thing? Evernote helps you take and edit notes, capture photos, create to-do lists and record voice reminders. Don’t feel like taking notes during a long meeting? Take a picture of the whiteboard and capture the audio. You can even organize your notes by notebooks and tags. The best part: The app syncs your notes across all your devices, so even if you’re not by your Android device, you won’t miss a beat.
