SnapDoc does not upload your documents to our servers. Your library stays on the phone or tablet, with folders, favorites, and search Lock the app with Face ID or Touch ID when the paperwork is sensitive ONE PURCHASE, NOT A SUBSCRIPTION Pro is a single unlock. It opens the full PDF toolkit and ID photo tools, and it removes the camera to PDF page limit. The price is shown on the App Store before you pay. Restore the purchase on a new device with the same Apple ID. BEFORE YOU SEND A FILE SnapDoc helps you make personal copies and packets to share. A landlord, bank, school, clinic, or government office may require a specific size or format. Confirm their rules before you submit. ID photo presets are print sizes, not a promise that any agency will accept the photo. Download SnapDoc and turn the page in front of you into a PDF you can sign, search, and send.

Verdict

The call

The clearest difference is in-app purchases: ClassLog at none against SnapDoc's 1. ClassLog also leads on iOS requirement (14.0 vs 17.6). SnapDoc's advantage is update cadence (fortnightly vs monthly). On price, ads and device support there is nothing between them.
