EyeShema 17+

“EyeShema” is a simple and interesting viewer of messages thru QR code(s) and 1D barcodes, and it can peel a compressed message or a locked message.

In general, the key feature of EyeShema is a scanner of QR code and 1D barcode. 
Thru a command picker, you scroll to your command. Press “Action” button to perform your selection.
(Command Picker: “Scanner”) (Camera is required/ Location (as a reference) is required)

A QR-code scanner in AR mode is used for my demo QR codes. Press “Play” at bottom. The app will set up environment for you. There are some of my demo QR codes for your practice. Finally, quit this app to reset this demo.

View/ Export/ Clear history records. (Reminder: QR codes in Photos is not recorded in history except (for ** view **) in AR environment)
(Command Picker: “View History”/ “Recent Location Records”/ “Export History”/ “Clear History”)

View the checklist/ Import or Paste [a list] to checklist.
(Command Picker: “View checklist”/ “Import to checklist”/ “Paste to checklist”)

You can import a list of codes (separated by line break) from your Documents folder or 
you can copy a list of codes / messages from Pages, MS WORD, Webpage or Text File and 
paste them to the checklist. To deactivate the checklist (audit mode), you should restart the app.  
For game playing (such as Orienteering/ Scout Orienteering Camporee), the instructors may send
a text file of to-do-list in each checkpoint to the player groups (iPhone/ iPad with this app) and
they can return their own history records to the instructor thru AirDrop of this app directly 
because the history records have already contained timestamp, GPS information and code type 
of scanned code(s) at the relevant checkpoints without further editing (Note to the orienteering
instructors: please record GPS information of QR codes in the relevant checkpoints first) 
(Reminder again: Scan QR codes in “Photos” will not be recorded in history except (for ** view **) in AR environment).
