Ratings and Reviews

5 stars for Effort


I will rate this 5 because there is nothing like it. Perhaps I'm getting the "B team" at 4am but it was hit or miss on the questions. They would often not listen to the audio.... If say "what color is this candle and can you tell me what scent.... I got "glass candle". From "two" web workers.... I pointed the camera at the floor and said "do you guys even listen to the audio?". And one of my answers was "white" and the other was "the image is not clear as it is very close" I see that the people are paid because one of the workers just pasted this message as his answer.

"This HIT is designed to quickly and accurately answer questions about photos and describe audio. We pay you to answer the questions quickly and accurately and will review all answers in 24 hours"

Wonder what HIT is?

Again, I see the value in this program and I want it to be very successful but of the review process for the web workers is not working they need to figure something else out.

I'd suggest a higher priced or subscription based "pro version" that used higher paid workers that actually care. I'd like to make some suggestions on the interface as well but until this other problem is fixed the program "Recognizer" would be a better program to have. provided someone can help you initially.

It works relatively well, but it is a bit slow.

The app works as advertised. However, the app tends to lag for about 30 second after you have finished recording your question. I don't know why this lag time exists, but reducing it would be great. It would also be nice to have the ability to send a message to a web worker who has just attempted to answer a question. At times, the web worker's answer is unclear, or insufficiently detailed, and you'd really like to just get clarification from that person rather than resubmitting the picture.


Club bullet

If this app continues to perform as it has so far, I will say that it is the very best app I have downloaded thus far and believe me, I have downloaded a lot of them since I got my IPhone! The interface is very straightforward, no frills and that's the way I like them. The app has correctly identified a package of frozen fish plus the color of the shirt I'm wearing today. Will continue to play with and evaluate this app but so far I am very very impressed!!!
