Skill Builder Annotation Apps

I am looking for examples of annotation apps schools are using with Skill Builders.  I recall the West Allis schools in Wisconsin used Notability.

These are links to 2 documents describing 10 apps for android and 10 apps for iPad devices.

• 10 Top Android pdf annotation devices.
• 10 great annotation devices for iPads

I am asking my colleagues for more examples.

• Suzy suggested Annotate  Looks pretty comprehensive
• Notability
•  Google’s Ed suite 
• I-annotate.
•  Kami is becoming a thing. I should try it:  https://chrome.google.com/webstore/detail/kami-pdf-and-document-ann/iljojpiodmlhoehoecppliohmplbgeij?hl=e

1/2019 from Lexia Customer Support. If the website makes it so that the student can edit the PDF, they may be asked for a password. Support has heard from other schools that when they try to edit the PDF they are asked for a password.
