Paper Pro has no conventional app store. That is a limitation if you want Slack, Teams or a specialist app on the tablet, but it is also the reason the device is easy to understand in a meeting. Notes, PDFs, folders, tags, handwriting search and export live in one consistent system.
reMarkable documents imports and uploads through Google Drive, Microsoft OneDrive and Dropbox. Its mobile and desktop apps extend the workflow, while Connect adds features including unlimited cloud storage, handwriting search and app-based note editing. Check the current subscription terms before treating those features as part of the purchase.
The company also publishes unusually specific security information for Paper Pro. Its business security guide describes block-level device encryption with a PIN-protected key, plus encryption at rest and in transit. That does not automatically satisfy your employer's policy, but it gives an IT team something concrete to assess.
