Blast your handwritten notes with this digital notebook to popular cloud services like Google Drive, Dropbox, Evernote, box, OneNote, Slack, iCloud, iMessage, email and more using the free Rocketbook app for iOS and Android. The app's OCR functions can also automatically name your files and transcribe your notes to text! Digitally scan your notes to save and share with colleagues, students and friends.
