Google Keep 

Google Keep allows you to capture quickly what's on your mind and share those thoughts with friends and family. You can add notes, lists, and photos to Google Keep; record a voice memo and Keep will transcribe it, so you can find it later; share your notes with others and collaborate on them in real time; add labels to notes to organize them quickly, and more. Everything you add syncs across all of your devices, so your thoughts are always with you.
