I came across this application through random google search and decided to download it onto my android phone to test it out.
Basically the idea is you have a question on any subject, you can just take a snapshot of the question and just *scream* for help. Any kind souls with the answers will reply back taking a snapshot of their solutions. Others may post comments on the questions of the solutions provided.
As far as I know, you cannot access to the poster’s or answer provider’s information. This includes their email address even if they want to share. This actually makes it hard for tutors trying to promote themselves by offering free help.
Overall my experience with this app is pretty positive, just that sometimes it crashes with my phone. Another area of improvement is that whenever you go back to the question page it does not stay at your previous position and you have to search for it all over again. Since this is free, I thought it is good for students to post questions and train their mastery skills through providing solutions. However I suspect some parents uses this platform to find answers for their kids instead. I have seen adult posters asking primary school math questions.
This is not encouraged as I believe one way to learn is to let the kid’s hands get dirty.
