Experience
AddPointment
Draftings Note Taking
Drafting helps avoid accidentally sending incomplete or embarrassing drafts or poorly edited messages by having a separation of concerns from the main note application the user is using.
Get drafts all set up within the app and have them automatically deleted with the drafts expiry feature done within the settings. We hope users enjoy using Drafting as a notes application as well.
