Photograph tests directly
No scanner needed: your phone's camera is enough. Take a photo of each page: any taken at an angle is straightened automatically.

Questions about the app
Is the app free?
Yes, it is a free download on Google Play. It opens the same account as the website: the free plan grades 30 pages a month with no credit card, and paid plans include more.
Do I need a web account?
You need a Correxio account, but you can create it right in the app, with your email or Google. It is the same account as on the website, so your batches show up on both.
Is there an iPhone version?
There is no iPhone app yet. On iPhone and iPad, Correxio works in Safari with the same features, photographing tests included.
