I just discovered that PDFpen Scan+ was discontinued, and went on a mini quest to find a replacement. I landed on ‎Scanner Pro.

I also considered:

• ‎Adobe Scan, but it will only store scans to the Adobe cloud.
• ‎Microsoft Office Lens, but this seems tailored to the OneDrive environment.
• ‎ScanPro, but the price is too steep for my frequency of use.

Scanner Pro works with most of the cloud environments, so I have it pointed at a folder in Dropbox that gets slurped into my inbox. A scan can also be initiated from Shortcuts, so I’ve removed the app from my homescreen.
