About Google Keep - Notes and lists
From the developer's description on Google Play.
Quickly capture and share your thoughts, manage your to-dos, and stay organized. Google Keep has all of the functionality you need, with advanced security and privacy measures to keep your information safe.
Capture what’s on your mind • Inspiration strikes anywhere. Jot down a quick note, snap a photo of something you want to remember, or speak a voice memo on the go. • Take advantage of widgets on your phone and tablet and add tiles and complications to your Wear OS device to quickly capture your thoughts.
Share ideas with friends and family • Manage your grocery list or plan your next trip by sharing your Keep notes with others and collaborating.
Find what you need, fast • Color and add labels to notes to quickly organize and get on with your life. If you need to find something you saved, a simple search will turn it up. • Pin notes to your phone or tablet homescreen with widgets and add shortcuts to your notes with tiles on a Wear OS device.
The right note at the right time • Need to remember to pick up some groceries later this week? Set a reminder to bring back your grocery list right when you need it.
Always within reach • Keep works on your phone, tablet, computer and Wear OS device. Everything syncs across all of your devices so your thoughts are always with you.
